Abstract

In order to study the dynamic roll stability of wheel loader,a ten-degree-of-freedom roll dynamics model of wheel loader with dynamic coordinate system was constructed based on the Lagrangian method considering body roll and boom pitch.The roll response under the coupling excitation of non-stationary road surface and engine was calculated and the dynamic lateral transfer load equation was deduced to characterize the roll stability.The influence trend of lateral slope angle, boom structure parameters and turning speed parameters on the roll angle and dynamic transfer load was analyzed.The results show that the body roll angle and dynamic lateral transfer load raises with the increase of lateral slope angle, boom mass and lifting angle, as well as turning speed.And the lateral slope angle and boom lifting angle have higher sensitivity on the roll stability.When the body roll angle exceeds the critical lateral slope angle, the vertical load on both sides of the wheels completely shifts,laterally and dynamically.Causing the fact that one side of the vehicle is off the ground, which leads to roll.The above models and dynamic lateral load transfer characterization methods can provide a research method and theoretical basis for subsequent performance optimization.
