Hybrid Electrical Air-Cushion Tracked Vehicle for Swamp Peat in Malaysia

摘要

The aim of this paper is to present a hybrid electrical air-cushion tracked vehicle (HETAV) for the operation onswamp peat. Mathematical models are incorporated with accounting kinematics and dynamics behaviors of the vehicle.Sinkage of the HETAV is sensed by an ultrasonic displacement (UD) sensor, in order to operate the air-cushion system.The air-cushion of HETAV is protected with a novel-design auto-adjusting supporting (AAS) system. A propeller isequipped with the vehicle to develop additional thrust for overcoming the dragging motion resistance of the air-cushionsystem . The performance of the HETAV is defined by traction and motion resistance. The mean value of traction for theswamp terrain with propeller over without propeller increases 10.21% and 6.47% for the vehicle weight of 1.02 kN and2.04 kN, respectively. Similarly, it was found that the mean values of vehicle’s motion resistance decrease 12.63% and25.81% for the vehicle weight of 2.45 kN and 3.43 kN, respectively.
