拖拉机前桥部份的板弹簧处于一种复杂的应力状态中,因为它要承受作用在拖拉机上的全部外力。板弹簧大量的疲劳破坏是由垂直载荷所引起的。本文的目的是要象复杂的动力学系统的弹性元件一样,研究弹簧寿命的计算方法。
The leaf spring of the tractor front axle part is in a complex stress state because it is subjected to all the external forces acting on the tractor. A large number of leaf spring fatigue damage caused by the vertical load. The purpose of this paper is to study the calculation of spring life as the elastic elements of a complex dynamical system.
