| 摘 要： | 利用描述函数和基波快速求解非线性条件下货车转向架的蛇行极限环,可以直接获得稳态下转向架主要部件的振幅、相位与频率等模态特征。通过对导出的非线性方程运用数值迭代方法求解,给出了某货车转向架在不考虑和考虑轮缘接触2种情况下的极限环解。

| Abstract: | Rapid solution of the hunting motion limit cycles on freight car bogies under non-linear conditions with the describing function and fundamental wave can directly find such modal features as the amplitude,phase and frequency of the bogies under steady-state conditions.With the use of the numeric iteration method for the derived non-linear equation,the solutions of the limit cycle on certain freight car bogie under the two conditions of with and without consideration of wheel-rail contact are given. |
