摘　　要：根据冲击振动压路机实验样机结构设计图纸的几何参数,在AN SY S中建立样机机架的有限元模型;结合样机机架所承受的外部简谐激励载荷的频率范围,对其进行有限元谐响应分析以及谐载动态性能估计。Based on the geometric parameters in the designed drawings of prototype structure of an impact and vibration roller,the finite element model was established. The finite element harmonic response analysis of the experimental prototype sketch was conducted, within the frequency range of the harmonic loads outside the sketch regarded. At last, the harmonic dynamic property of prototype sketch was estimated.
