板焊前轴壳结构设计及强度校核研究

文章主要介绍了板焊结构前轴壳的设计过程及强度校核方法。首先,根据整车需求设计板焊前轴壳的落差、主销中心距及前轴壳截面尺寸;其次,根据板簧宽度及位置设计板焊前轴壳折弯点及折弯角度,确定折弯处圆弧半径;最后,根据前轴壳结构及受力位置确定危险截面,根据第4强度理论对各个危险截面进行应力分析,确保其满足强度要求。

Structure design and intensity checking research of Welding Front Axle of Mining Dump Truck

This paper introduce the main design process and strength checking method of Welding Front Axle.According to the requirements of the vehicle,the drop of the welding front axle,the center distance of the main pin and the cross section of the front axle shell are designed.According to the width and position of the suspension system,the bending point,bending angle of the welding front axle and the arc radius at the bending position are designed.Finally,determining the dangerous section according to the structure and checking the welding front axle housing and analyzing the stress of each section according to the theory of the fourth strength ensure proper selection.
