| Euler Disc Spring DeltaTheta CAD Input Parameters · member download · original: DeltaTheta CAD Input | This workbook defines CAD inputs for an Euler-profile disc spring with a 100 mm outside diameter, 50 mm inside diameter, 6 mm thickness, and 8.2 mm free height. It organizes generatrix rotation through DeltaTheta increments for CAD or SolidWorks modeling and later parameter sweeps. The data describe geometry only and do not certify strength, fatigue life, or production readiness. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Top 10 Fatigue Candidates for a 50CrVA Euler Disc Spring · member download · original: DiscSpring 50CrVA Fatigue Top10 | This workbook ranks fatigue candidates for a 50CrVA Euler-profile disc spring using native Fe-Safe life, SWT life, and factor-of-safety results. The current screen fails the one-million-cycle target. Provisional plasticity, debugging mesh, uniform residual-stress assumptions, and missing test calibration remain blockers, so the ranking supports design comparison only and is not a released design. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| EDS 100-50-6-8.2 R1 Euler Disc Spring Geometry Drawing · member download · original: EDS 100 50 6 8p2 R1 | This one-page drawing defines the nominal geometry of the EDS 100-50-6-8.2 R1 Euler-profile disc spring: 100 mm outside diameter, 50 mm inside diameter, 6 mm thickness, and 8.2 mm free height. It also records 1 mm edge radii, DeltaTheta of 10 degrees, and zero initial curvature. It is a modeling reference and contains no material, load, or acceptance result. | reference_pdf / engineering-outputs | — | — | company_owned / public |
| EDS 100-51-6-8.2 R1 Euler Disc Spring Geometry Drawing · member download · original: EDS 100 51 6 8p2 R1 | This one-page drawing records the nominal dimensions of the EDS 100-51-6-8.2 R1 Euler-profile disc spring: 100 mm outside diameter, 51 mm inside diameter, 6 mm thickness, and 8.2 mm free height. It specifies 1 mm edge radii, DeltaTheta of 5.13136 degrees, and zero initial curvature. The sheet supports CAD and FEA geometry checks but is not a performance or manufacturing approval. | reference_pdf / engineering-outputs | — | — | company_owned / public |
| DeltaTheta Bisection Screen for a 51 mm ID Euler Disc Spring · member download · original: Euler Disc Spring DI51 DeltaTheta Bisection | This workbook applies a bisection search to DeltaTheta while holding the geometry at 100 mm OD, 51 mm ID, 6 mm thickness, and 8.2 mm free height. The 5.625-degree trial passes the 1500 MPa stress and 0.5 mm permanent-set screens, but its SWT life is about 28,105 cycles versus a one-million-cycle target. Force is unconstrained, so the point is not release-ready. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| L18 Design-of-Experiments Analysis for an Euler Disc Spring · member download · original: Euler Disc Spring L18 DOE Analysis | This workbook analyzes an L18 parameter experiment for an Euler-profile disc spring. Nine of eighteen cases pass the current physical screen, and the thickness factor has the strongest effect on log fatigue life. The best observed case, DOE012, reaches about 34,265 cycles, still below the one-million-cycle target. A confirmation plan is included, making the file useful for factor ranking and follow-up design rather than final validation. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Euler Disc Spring Parameters and SolidWorks Modeling Guide · member download · original: Euler Disc Spring Parameters | This workbook defines dimensions, curvature inputs, and a SolidWorks workflow for an Euler-profile disc spring. DeltaTheta is a required design input, while curvature follows the linear form kappa at zero equals zero and kappa of arc length equals a times s. A polynomial Fresnel approximation is provided. The file supports parametric modeling and input validation; it does not replace FEA or physical testing. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Surrogate-Model Variables, Constraints, and Sampling for an Euler Disc Spring · member download · original: Surrogate Model Variables Constraints Sampling | This workbook plans Stage 1 of an Euler disc spring surrogate model with variables, constraints, and 28 initial evaluations: four anchors plus 24 optimized maximin Latin-hypercube points. Its gates cover numerical validity, plastic strain and permanent-set screens, surrogate quality, life optimization, force tie-breaking, and direct FEA confirmation. It is a controlled sampling and decision workflow, not a validated performance result. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Unified Parameter Package for Arbitrary Multi-Segment Disc Springs · member download · original: arbitrary multisegment parameter package | This workbook uses a unified table schema to describe arbitrarily ordered multi-segment disc springs. The MIX70 example combines cone, sphere, hyperbola, Euler, and NURBS segments and records G1 join tolerances, fillets, supports, spline control points, and knots. It is intended as a CAD/FEA data-exchange template. The example validates the schema and should not be interpreted as an optimized production design. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| General Multi-Segment Disc Spring Parameter Package · member download · original: general multisegment parameter package | This parameter package separates batch, design, segment, join, and output data for general multi-segment disc springs. Its MIX70 R1 example has a 70 mm outside diameter, 40.5 mm inside diameter, 6.5 mm total height, and a five-segment profile. The workbook standardizes parameter exchange and modeling input across curve types. The sample demonstrates the format and contains no load, stress, life, or manufacturing acceptance result. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| MS70-40.5-S500-S300 Two-Sphere Disc Spring Parameter Package · member download · original: multi segment spherical parameter package | This workbook defines the MS70-40.5-S500-S300 segmented spherical disc spring with a 70 mm outside diameter, 40.5 mm inside diameter, and 6.5 mm total height. Its generatrix contains two spherical segments with radii of 500 mm and 300 mm, each occupying half the radial span. The package supports geometry generation, interface checks, and later simulation input; it contains no material model, load curve, or validated performance claim. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Corrected Presetting DOE for D31.5 Disc Springs at HRC42–52 · member download · original: d315 corrected hrc42 52 doe | This workbook compares presetting responses of a D31.5 disc spring across six HRC42–52 labels. It screens for a fifth-unload height of 2.450 plus or minus 0.005 mm and reports linearized material inputs, initial height, overtravel, peak force, plastic strain, and residual stress. All six cases pass the height screen, but the hardness mapping and material parameters are DOE assumptions that require formal conversion data and test calibration. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| D31.5 HRC42–52 Presetting DOE and Stress-Contour Summary · member download · original: d315 HRC42 52 DOE stress clouds | This workbook summarizes a D31.5 multi-hardness presetting DOE and associated stress contours. All six hardness points pass the fifth-unload height screen; overtravel spans about 0.00217–0.00875 mm and peak force about 175.8–539.6 kN. The file explicitly treats the HRC-to-tensile-strength relation as a linear labeling assumption and warns that contact-sensitive peak forces must not be compared with the A-L product flattening force without material and test calibration. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| D31.5 HRC46 Disc Spring Presetting DOE · member download · original: d315 HRC46 presetting DOE | This workbook screens presetting parameters for a D31.5 HRC46 disc spring. The selected case uses a 2.75 mm initial height, a 2.45 mm target, and 0.00217 mm overtravel, producing a fifth-unload height of 2.450177 mm. The FEA load at 75 percent travel differs from the A-L value by about -0.09 percent, while the contact-sensitive peak force remains high. Material and physical-test calibration are still required. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Fifteen-Pass Presetting FEA Report for a D60 60Si2MnA Disc Spring · member download · original: D60 60Si2MnA 15遍强压FEM报告 | This report evaluates height and residual-field convergence during fifteen presetting passes on a D60 60Si2MnA disc spring. Free height decreases from 5.35 mm to about 4.9627 mm, with the first pass contributing roughly 69.9 percent of total settlement; the combined height and residual-field criterion identifies the first eight passes as most significant. The material model is a non-certified proxy, so the report supports process-trend assessment and still requires test calibration. | working_document / engineering-outputs | — | — | company_owned / public |
| Batch Input Template for Disc Spring FEA · member download · original: fem batch template | This workbook is a product-list template for batch disc spring FEA. Its fields cover outside and inside diameter, thickness, initial and target height, hardness, yield input, cycle count, loading timing, friction, mesh settings, and contour output. The example row uses D31.5 dimensions and HRC46 parameters solely to demonstrate the batch schema. Reviewed product and material data must replace the sample before engineering use. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| Final-Product Input Template for Disc Spring FEA · member download · original: fem final product template | This workbook defines the minimum final-product inputs for a single disc spring FEA case, including outside and inside diameter, thickness, finished height, HRC, yield strength, the 75-percent-travel multiplier, hold settings, and recovery settings. The sample uses a D31.5 spring with 16.3 mm ID, 1.75 mm thickness, 2.45 mm finished height, and HRC46. These values demonstrate the format and are not production instructions. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
| S300/S500 Segmented Spherical Disc Spring Validation Package · member download · original: validation s300 s500 parameter package | This validation package defines a segmented-profile disc spring with 70 mm OD, 40.5 mm ID, 4.7 mm thickness, and 6.5 mm free height. It compares S300 and S500 spherical segments with a conical segment and records support positions, G1 joins, tolerances, and fillets. The file validates multi-segment geometry generation and interface continuity; it does not provide complete material, load, or life validation for product release. | engineering_workbook / engineering-outputs | — | — | company_owned / public |
