MODELLIZATION OF THE SPECIAL SEGMENTED RUBBER TRACKED VEHICLE DESIGN PROCESSES ON PEAT TERRAIN IN MALAYSIA

Abstract

Discussion on the modellization of an off-road special segmented rubber tracked vehicle on low
bearing capacity Sepang peat terrain design processes is the main focus of this paper. To
complete this study, first the mechanical properties of peat terrain were determined by using
different type of apparatus. Direct shear test was performed using a Wykeham Farrance 25402
shear box apparatus to determine the internal friction angle, cohesiveness and shear deformation modulus of the peat sample. Load-sinkage lest was performed using a speciually made bearing capacity apparatus to determine the stiffness wIlues of surface mat and underlying peat. Secondly. mathematical model was developed for computing tbe vehicle tractive performance. Thirdly. design parameters of the special segmented rubber tracked vehicle were optimized by simulation method using Microsoft Excel with analyzing the information and managing list in powerful spreadsheet. Finally, vehicle design was completed based on the simulated optimized design parameters by using Auto-CAD software package.
