Traction Performance and Dynamic Matching Analysis of Wheel-Track Composite Amphibious Vehicle

Amphibious vehicles play an important role in logistics support and material transportation. However, the problem of poor traction and passability of amphibious vehicles in the tidal flat area still needs to be solved urgently. In order to solve the problems, a wheel-track composite amphibious vehicle (W-TCAV) driving system is proposed, and the high mobility of wheeled vehicles and the high passability of tracked vehicles are integrated; According to the configuration of the W-TCAV, the model of terramechanics and driving kinematics are established; Based on the control program of Matlab/Simulink, it is verified that the W-TCAV has obvious advantages compared with wheeled vehicles in terms of traction and passability; Based on the driving characteristics of W-TCAV, the influence of power matching on the traction passability is studied. The simulation results show that the traction performance of the W-TCAV can be effectively improved in the tidal flat area, and the traction performance can be significantly ameliorated by maintaining the consistency of wheel-track power matching.
