摘　　要：某型工程车辆,在可靠性试验过程中,驱动桥桥壳若为冲焊结构,会经常从推力杆支座焊缝位置开裂,影响试验效率。对桥壳进行试验研究发现平衡悬架结构在搓衣板路上存在低频“拍击”附加力,并会引起簧上共振,使推力杆座焊缝位置的应力异常增大,容易产生裂纹。During the reliability test of a certain type of engineering structure,if the drive axle housing is a punching and welding structure,it will often crack from the weld position of thrust rod support,which affects the test efficiency.The experimental study on the axle housing shows that there is a low-frequency"slapping"additional force of the balanced suspension when running on the washboard,which causes the spring resonance and makes the stress of the thrust rod seat weld abnormal increase,and produce cracks easily.

关 键 词：驱动桥 平衡悬架 低频附加力 簧上共振
