摘要
采用直接微分法得到了一种弹性连杆机构稳态动力响应灵敏度的计算方法，该方法克服了用差分法计算灵敏度存在的截断误差和舍入误差较大、计算精度低的缺点，是一种精确有效的弹性连杆机构稳态动力响应灵敏度计算方法．文中给出了一平面四杆机构的灵敏度分析实例来说明方法的有效性．
Using the direct differentiation method,a design sensitivity analysis method for the steady state dynamic response of elastic linkages is developed.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. An example problem of the sensitivity analysis of a planar four-bar elastic linkage is presented to show the validity of the proposed method.
