Lateral Stability Analysis of Telehandlers Based on Multibody Dynamics
Authors: , , ,
Abstract: At the beginning, this article analyzed the lateral stability of telehandlers, and reached the following results: the critical overturning angle, the critical sliding angle, and the conditions of sliding happen before overturning. Then, the ADAM virtual prototype of telehandlers was built based on the multibody dynamics model, and the dynamic simulation of the lateral stability of telehandlers was carried out, and then we got the rule of that the right tire reacting force change with the critical overturning angle with frame leveling or not. Base on the ‘UA’ model of tire, we studied the influence of vertical stiffness and lateral stiffness on the lateral stability of telehandlers. The result of virtual simulation method was compared with that of the theoretical calculation and platform experiment. It can be seen that the result of the virtual simulation method is closer to the actual situation, and can shorten the development process and reduce the cost, which can guide the structure design of telehandlers more scientifically. This article can also provide reference for the design of the lateral stability of the rear axle articulated vehicles.
