D31.5 disc spring A-L/FEM correlation
The D31.5 R0.25 axisymmetric contact model differs from A-L by approximately +1.57% at 75% travel.
Equal-displacement comparison of A-L, manufacturer, FEM and experiment within the declared range.
Abaqus Standard
51CrV4；E=206000 MPa；ν=0.3；isotropic elastic
二维轴对称模型；下刚性压板约束，上刚性压板施加轴向位移。
仅适用于 D31.5×16.3×1.75×2.45 名义几何、R0.25 截面及 20%~75% h0；100% 附近接触锁死，不作为 FEM 载荷验证。
刚性压板与 R0.25 矩形圆角截面接触；完全压平段存在接触锁死。
R0.25 圆角矩形截面结构网格，322 节点、270 单元。 75% 行程同位移相关性已确认；完全接触段因数值刚化排除。
