摘　　要：针对曲轴因疲劳而导致在曲柄内拐角处容易出现斜向裂纹的问题,采用CAD建模然后导入到AN-SYS中,用ANSYS有限元分析法模拟分析含裂纹曲轴的振动特性。通过对一单缸实验型曲轴的模态分析和动态响应分析,研究裂纹对曲轴振动特性的影响,为实现曲轴裂纹动态监测打下基础。Against fatigue caused by the crankshaft within the crank corner diagonal cracks easily. In this paper, and then introduced into CAD modeling ,finite element analysis simulation cracked crankshaft vibration. Based on a single-cylinder crank experimental modal analysis and dynamic response analysis, the crack of the crankshaft vibration characteristics, crankshaft crack lay the foundation for the realization of monitoring.

关 键 词：曲轴 裂纹 模态分析 CAD
