摘　　要：利用全微分法对含有一个移动副的五杆机构的杆长误差导致的机构误差进行计算,并对计算结果进行了相应的分析,通过对机构位置方程组求全微分得到相关的误差方程,从而解出位置误差。利用Matlab软件进行仿真计算,更加具体地展示出机构上尖点位置误差随曲柄的旋转而变化的曲线,从而精确地分析出各连杆长度精度对尖点位置的影响。The five- bar mechanism＇s error,which caused by rod length error,was calculated and analyzed using the total differentiation. The relevant error equation was obtained by dealing with institutional position equations; and the equation was solved to get the position error. Software simulation was conducted by Matlab. The change curve of point Μ in the precise mechanism of the position error with the rotation of the crank was then more specifically demonstrated. The influence of the connecting rod length precision on point Μ location was analyzed accurately.
