longitudinal metacentric radius

By analyzing the characteristic of the structure of the hydraulic modularized combined trailer, the author first deduces the formula of the minimum longitudinal passing radius when the trailer passes the concave-convex road and the maximal ramp angle when it climbs the ramp, and then calculated the passing capability of the typical trailer.

通过对液压模块组合挂车结构特点的分析,推导出了其通过凸凹路面时的最小纵向通过半径和通过斜坡时的最大坡度角的计算公式,并对典型车型的通过性能进行了计算。
