摘要
建立变长杆弹性连杆机构的精确运动微分方程，运用转移矩阵法直接求解；对动应力进行傅里叶级数逼近，取前Ｎ项傅里叶级数为动应力数值解的近似值，进而分析频域特性。
The solution is directly found by establishing the differential equations of the accurate movment of the variable length rod elastic linkage mechanism and using the transition matrix method.The dynamic stress is approached by Fourier series.The first N terms of Fourier series are taken as the approximate value of the dynamic stress figure solution,and furthermore,the frequency field characteristics are analyzed.
