摘要
福田欧曼GTL年度型6×4牵引车在进行可靠性试验时,尾灯支架在行驶过程中出现振动疲劳失效,为此采集了尾灯支架的激励载荷,并将激励载荷加载于尾灯支架有限元模型上进行振动疲劳分析,计算结果与可靠性试验损伤部位吻合,通过分析疲劳寿命结果,重新设计了新方案,大大提高了尾灯支架的振动疲劳寿命。并通过台架试验验证了分析结果的一致性。
FOTON AUMAN GTL type6×4tractor in the reliability test,taillight support in the course of vibration fatiguefailure,For this reason,the excitation load of the taillight support is collected,and the excitation load is loaded on the finiteelement model of the taillight support,Through the analysis of the fatigue life results,a new scheme is redesigned,whichgreatly improves the vibration fatigue life.The consistency of the analytical results is verified by bench test.
