Title Structural Analysis on Steering Linkage of Heavy Vehicle
Abstract
With the infrastructure and engineering construction's needs, a number of high-power, high-load carrying capacity of heavy vehicles has been widely used. As heavy vehicles usually have a long body, due to restrictions on work sites and roads, asking them to turn radius controlled in a certain range, so heavy vehicles used more multi-axis steering technology, and the performance of its steering behavior restricts the development of its own to some extent. For muti-axis heavy vehicle, they have a few more steering axle, and its tire wear and steering linkage damage usually happens in actual process. In order to make a better steering behavior, reduce tire wear and steering linkage damage, it is necessary to do further study on muti-axis Steering technology. This paper was based on ADAMS/View software platform, using mufti-body system dynamics and virtual Prototype theory to do structural dynamic analysis on Steering Linkage.
