Abstract

The tractive performance justification of an off-road vehicle is so important that it ensures the vehicle mobility over the unprepared peat terrain. Tractive performance of Low Ground Pressure (LGP-30) wheeled vehicle is investigated on the low bearing capacity moderate peat terrain in Malaysia. The simulation results showed that the vehicle sinkage is more than the critical sinkage value of 100 mm, ground contact pressure is more than 17 kN/m 2 , and rolling motion resis- tance due to terrain compaction is very often more than the tractive effort of the vehicle. The vehicle was tested on the un- prepared moderate peat terrain after increasing the tyre-terrain interface by decreasing the tyre inflation pressure of 5%, 10% and 15% respectively. The vehicle was found to traverse on the terrain smoothly when the tyre inflation pressure was decreased by 15%.

Highlights

Typical peat characteristics as found in Malaysia are the presence of submerged and un-decomposed woods, stumps and logs
This study indicates that the vehicle sinkage for the LGP-30 wheeled vehicle should not be more than 0.48 m as the vehicle ground clearance is 0.48 m and the maximum slippage should not be more than 40% in order to allow the LGP-30 vehicle to move
Sinkage and slippage increased with increasing of the terrain moisture content

Summary

Introduction

Typical peat characteristics as found in Malaysia are the presence of submerged and un-decomposed woods, stumps and logs. These submerged and unrecompensed logs or stumps impede the movement of machinery in the field. Under the loaded surface some of peat soil may be at rest while others may move down. It is very difficult to manage any vehicle operation on peat terrain to do the transportation of palm oil fresh fruit bunches and other goods. This study investigates the LGP-30 wheeled vehicle tractive performance investigates through theoretically and experimentally. The major purpose of this study is to justify the LGP-30 wheeled vehicle suitability over the moderate peat terrain in Malaysia
