摘　　要：用试验模态的分析方法对摩托车车架的强度进行了研究，找出了车架的各阶固有频率，分析了路面波动、发动机振动对车架强度及变形的影响。The structural strength of a motorcycle frame is studied by its modal testing. Various modal freguencies of the frame have been found. The effects of road and engine induced vibrations on the strength of the frame are disscused, and the relativly weak areas in the strength of the frame are pointed out.
