摘要
基于Ansys的结构随机振动疲劳寿命分析模块,在随机路面不平度激励下,以陕汽SX3255DM354型工程车辆前桥为研究对象,结合Miner线性累积损伤理论和材料P-S-N曲线,预测车桥结构理论疲劳寿命。
Based on ANSYS module to analyze the random vibration of the axle, under the road roughness random vibration, taking the front axle of type SX3255DM354 engineering vehicle produced by Shan Qi as the research object, combined with Miner liner cumulative law and P-S-N this paper obtained the theoretical fatigue life of the engineering vehicle axle.
