摘要
本文针对一种凸轮连杆复合机构 ,在运动弹性动力学分析的基础上运用直接微分法得到该机构的稳态动力学响应灵敏度的计算方法。该方法克服了用传统差分方法计算灵敏度时存在的截断误差和舍入误差较大、计算精度较低的缺点 ,是一种精确的灵敏度计算方法。
Based on the KED analysis,a design sensitivity analysis method for composite elastic linkages is obtained by using the direct differentiation method this method does not suffer the round off and truncation errors that plague the finite difference sensitivity results,thus it is more accurate and efficient than the finite difference method.
