    在通用型机械强度超速试验机的柔性系统中,柔性轴在高转速下会出现变形过大的问题,影响试验结果的准确性。结合以往设计经验,在理论研究的基础上,利用有限元法和拉格朗日方程建立柔性轴系运动方程,运用Matlab求解出相应的质量矩阵、刚度矩阵,得出了柔性轴系在瞬态和稳态情况下的运行情况。并利用Adams进行柔体动力学分析,得出在瞬态和稳态情况下柔性轴系的运行情况与理论计算结果进行对比,其结果基本一致,验证了理论计算和系统柔性仿真的正确性。 In the flexible system of general purpose mechanical strength overspeed testing machine, the flexible shaft will have excessive deformation under high speed, which will affect the accuracy of the test result. Based on the previous design experience, based on the theoretical research, the finite element method and the Lagrangian equation are used to establish the flexible axis system motion equation. The corresponding mass matrix and stiffness matrix are obtained by using Matlab, and the flexible shaft And steady state operation. The results show that the operation of the flexible shaft system is compared with the theoretical calculation result in the case of transient and steady state, and the results are basically the same, which verifies the correctness of the theoretical calculation and the system flexibility simulation.
