抱罐车抱罐工况刚弹性混合承整车稳定性校核方法

Method of checking stability of the rigid and elastic hybrid support body of slag pot carrier in holding cases

将抱罐车在抱罐工况下的车架结构(车架后端设置液压支腿)模拟为带悬臂的两跨刚、弹性混合支承连续梁的一次超静定结构,然后建立力的平衡条件和前、后轴轮胎的变形协调条件方程,最终求出抱罐车在抱罐工况下前、后轴载荷及支腿支撑力.通过计算抱罐状态抱罐车前桥轮胎的变形回弹量来检验前桥轮胎是否离地,为校核抱罐车抱罐状态的稳定性和抱罐工况的安全性提供了一种有效的方法。

The frame structure(hydraulic ram at the rear of the frame)of slag pot carrier in holding cases is simulated as a statically indeterminate structure with one redundant of the two-span rigid and elastic hybrid support continuous beam with cantilever,and then the equations of force balance conditions and deformation compatibility conditions of front and rear axle tires are established,finally resulting in the loads of front and rear axles and support force of ram in holding cases.The paper proposes to check whether front axle tires are off the ground by calculating the deformation spring back of the front axle tires of the slag pot carrier in holding cases,which provides an effective method for checking the stability and safety of slag pot carrier in such cases.
