摘　　要：利用理论解析法与有限元仿真分析法相结合,研究了螺旋圆弹簧相对橡胶元件产生的转动角大小对其疲劳寿命的影响;从理论解析、有限元仿真、结构优化和疲劳寿命计算4方面优化研究了螺旋圆弹簧用橡胶元件疲劳破坏问题,并通过疲劳试验验证了优化结构的使用效果。结果表明,螺旋圆弹簧相对橡胶元件产生的转动角度对其疲劳性能的影响非常重要;优化后橡胶元件36万次疲劳试验后未出现疲劳裂纹,疲劳评估寿命为1.096×10^(6)次,优化后结构仿真疲劳寿命较原始结构提高了约4倍,疲劳性能得到明显提高。The effect of the rotation angle of the spiral round spring relative to the rubber components on its fatigue life were studied by using the combination of theoretical analysis method and finite element simulation analysis method,and the fatigue failure of rubber components for spiral round spring was optimized and studied from four aspects:theoretical analysis,finite element simulation,structure optimization and fatigue life calculation.The practical application of the optimized structure was verified through fatigue test.The results showed that the rotation angle had a significant effect on fatigue performance.After 360,000 fatigue tests,the optimized rubber components did not show fatigue cracks,and the fatigue evaluation life was 1.096×10^(6) times.The fatigue life was increased by about 4 times compared with the original structure,and the fatigue performance was significantly improved.
