Present work deals with the design and analysis vibration characteristics for transport utility vehicle. The transport utility vehicle is designed using automotive industry standards. The dynamic behaviour of vehicle depends on the selection of overall dimensions, wheel base, track width, overall height and width that are decided using central motor vehicle rules. The selected dimensions for vertical and horizontal pillar members of the transport bus are modified to enhance the strength, stiffness and stability of the superstructure during travel. This increased stability enhances the ride comfort and passenger safety. Analysing the effect of utilizing manual meshing in complex areas of a transport utility vehicle for vibration analysis and passenger ride comfort has also been carried out. Modal analysis to evaluate the dynamic behaviour of transport utility vehicle model is also carried. Further with the use of finite element analysis deflection vehicle structure is evaluated. The outcomes from the analysis are compared with the behaviour of chassis mounted platform in dynamic conditions and are found in close correlation. The vehicle structure behaves as a single entity in dynamic situations, so surface model is prepared. Element selection for the finite element analysis is carried by considering plane stress condition. Two-dimensional quadrilateral shell elements are extensively used for meshing of the computer model of the vehicle structure. Complex areas in the optimised vehicle structure are meshed using relevant combination of quads and trias. The values of vector sum displacement and frequencies are found to be in good agreement with the experimental ones.

Abstract

This paper deals with the design evaluation of chassis integrated structure intended to carry tractor trolleys. This structure is either bolted along with tractor trailer chassis or attached to the trolley using special attachments. Such structure is located in between the trolley chassis and tractor trolley. The role of this structure is to provide a support to the trolley during transportation in agricultural terrains. This structure transmits and upholds the load variations during tractor travel in agricultural terrains. Present work deals with design evaluation of one such structure. In this work, the structure under consideration is designed to house and support one axle semi-trailer trolley. Locations of attachment of the structure to the chassis or trolley depend upon the weight and size restrictions mentioned in Indian Standards. Major design considerations for the structure include height of the semi-trailer trolley, nature of load or cargo placed inside the trolley, restrictions on axle load and tractor geometry parameters as departure angle and ground clearance. In order to evaluate structure characteristics of stress and deflection computer simulation is carried for the road-load conditions. Road profiles for structure simulation and analysis include typical Indian agricultural terrains comprising of black cotton soil and soil lumps
