Stability Analysis of Walking and Lifting Column Platform

Abstract

Aiming at walking and lifting column platform of high stability requirements, moment balance method is used when stability and overturning moment are calculated under the most dangerous conditions. The ratio of the stability and overturning moment is obtained, namely safety factor, to determine the anti overturning stability of the mechanism, at the same time, the kinetic energy and potential energy are calculated by using the energy method, to judge the stability by the relationship between kinetic energy and potential energy. A certain lifting platform as an example, stability and overturning moment are calculated under the most dangerous conditions, obtaining stability safety factor K>1,When the maximum velocity is to pass through the barrier, kinetic energy 462 kg·m2/s2 is less than the potential energy 827.7kg·m2/s2,it shows that the stability of the mechanism is good.
