In order to study the dynamic characteristics of dump truck with a T-type lifting mechanism, a detailed multi-body dynamic model of a dump truck was established by using SIMPACK software. With this model, which includes front suspension, balanced rear suspension, carriage, lifting mechanism, tyre model and so on, the kinematics and dynamics of the dump truck were studied by simulation. The variation of angular velocity, angular acceleration and applied force of carriage, tension rod and cylinder with lifting angle were obtained. This study will provide scientific reference for the structural design and strength analysis of lifting mechanism. |
