VIRTUAL PROTOTYPE OF THREE WHEELED MOTOR VEHICLE FOR VERTICAL DYNAMICS EVALUATION

Abstract

Virtual prototyping is a modern technique utilized to estimate the performance of any vehicle or equipment to be used in real conditions, before its actual prototype can be built. This helps in removing many problems of design changes which concerns the manufacturing of any vehicle including a three wheeled motor vehicle (i'WMV), in reality. The tools used in such techniques are mainly CAI)/CAE SWs which help in modeling different complex parts of the model and then to assemble it into the full model. Once the model has been assembled with its different intricate parts, it can be simulated into virtual environment conditions, where it can be run and analyzed. Todayts SWs tools are state of art tools to analyze such models for its performance without going for manufacturing the prototype. Any design variation can be easily introduced and re-simulated. In present work, a model of Three wheeled motor vehicle (TWMV) has been made in CAL) software Solid Works 2012 (SW 2012), and simulated in the same for different road conditions. lhree road profiles used here include: Profile used for validating the model. Profile with a simple bump pattern. . Profile with an undercut pattern. These three profiles have been used to analyze the behavior of the TWMV when it passes over these three profiles. Various forces, accelerations and displacements have been plotted in the result and has been discussion. The curves have been plotted in two ways, one when each property measured on a particular part of TWMV has been plotted at diftrent speeds of the TWMV and other when at a particular speed the properties of the vehicle has been measured. The conclusion after analyzing these results has been plotted in the chapter of Conclusion.
