履带车辆传动轴疲劳寿命预测与结构改进
Fatigue life prediction on drive shaft of tracked vehicle and structure optimization
摘要
Abstract
Drive shaft is an important part in caterpillar ,and it is designed with the static strength theory within the limitation of test and experimental conditions .Thus the actual dynamic charac‐teristics of drive shaft cannot be embodied ,and it brings difficulty to predict the life of parts with given dynamic loads and results in wide gap between actual life and designed .The virtual running test platform was built based on ADAMS .ATV ,and the dynamic load suffered by drive shaft in different working condition was obtained .Then the fatigue life of drive shaft was analyzed with fatigue life prediction model of drive shaft established by MSC .Fatigue ,and the structure of drive shaft was improved .The study case proved the new method was feasible to predict fatigue life of drive shaft ,and tracked vehicles for fatigue life prediction under complex operating conditions were explored .The study results can widely extended to other engineering domains ,and the pro‐spective of analysis method applied in related engineering system is presented .关键词
