| 摘 要： | 应用Pro／E软件建立少林客车车架的三维模型，通过Ansys的专用接口导入Ansys软件中以生成有限元分析模型，并对车架进行模态分析和瞬态响应分析，求得车架的前7阶模态．在此基础上对结构进行改进，改进后的一阶固有频率为32．271Hz，介于非簧载质量的固有频率和怠速运转频率之间．假设汽车前轮突然受到路面一冲击载荷F0=200kN，持续时间td=1s的作用，对改进后的车架结构进行瞬态响应分析，得到位移响应的最大值为0．125mm．

| Abstract: | The three dimensional model of Shaolin coach chassis frame is established based on Pro/E, the finite element model is attained by introducing the Pro/E model into the Ansys through the special channel. Then the modal analysis is conducted, the first to seventh models are attained. Based on model analysis, the frame construction is improved; the first natural frequency of the improved model is 32.271 Hz, between the non-spring load natural frequency and idle speed running frequency. Given impact load 200 kN on the front wheel for 1 s, the transient analysis is conducted, the maximum displacement response is 0. 125 mm. |
