【Abstract】 Finite element method is used to analyse are calculate elastic and elastic-plastic stress and deformation on the back pedestal of rotary axle of tractor. The load conditions of the back pedestal in three typical cases are analyzed. Static stress contours and deformation contours are obtained. The results provide reliable theoretical basis for replacing material of this part.更多还原
