⚠ Calculation warning / 计算警告
Stress (2009 MPa) exceeds 80% of yield strength
Stress (2009 MPa) exceeds 80% of yield strength
⚠ Spring index high (92.0 > 20) / 弹簧指数偏高 (92.0 > 20)
Suggestion / 建议
Reduce mean diameter or increase radial wall width
减小中径或增加径向壁宽
✗ Stress exceeds 80% of yield (171.7%) / 应力超过屈服强度的 80% (171.7%)
Suggestion / 建议
Reduce load, increase thickness, or use stronger material
减小载荷、增加厚度或使用更强材料
i Multi-turn wave spring designed for crest-to-crest contact (P=2.67mm, A=1.33mm) / 多圈波形弹簧按波峰顶住设计 (P=2.67mm, A=1.33mm)
Continuous helix with alternating wave phase per turn; wave amplitude A = P/2 ensures adjacent turn peaks touch in free state.
采用连续螺旋上升并每圈波形交错；波幅 A = P/2，使相邻圈波峰在自由态接触。
