以南京地铁一号线刚性悬挂参数为依据,利用有限元模态分析法建立了接触网刚性悬挂自由振动的振型,列举出自由振动的各阶频率,并从模拟计算结果中分析了刚性悬挂的一些振动特性。
Based on the rigid suspension parameters of Nanjing Metro Line 1, the modes of rigid suspension free vibration of the catenary are established by means of finite element modal analysis. The frequencies of free vibration are listed. The rigid suspension is analyzed from the simulation results Some of the vibration characteristics.
