Study on Decreasing Wear and Dimensional Optimization of Linkage Mechanism with Clearance Joint

  • 摘要: 提出了机构尺寸优化、多体动力学、磨损预测三者的集成分析框架。铰接副由非线性弹簧阻尼模型结合修正库伦摩擦力来表达,采用Archard模型结合有限元接触模型进行磨损预测,并通过广义简约梯度法实现整体优化计算,最后针对连杆机构铰接副磨损问题进行详细分析计算。结果表明构件的角加速度峰值可有效表征机构振动和磨损程度,优化后摇杆的最大加速度幅值降低了71%,机构运动平稳性大幅提升;间隙铰接副轴套低磨损区域明显扩大,最大磨损深度降幅为36%,证明了该算法对含间隙机构摩擦学优化问题的有效性。
