Abstract

Vehicle stability generally depends on the tire forces and torque at wheel. Forces and reactions generated at tire play major role in the control of vehicle. On application of torque to the wheel, due to contact friction between road, tire pushes on the ground and moves forward and backward. Tire also supports the load of vehicle and deforms under load for the flexibility and damping. The stiffness of fluid in tire is the important parameter for tire stability and effectiveness. Inflation pressure in tire decides the stiffness and damping in the tire. The objective of this paper is to discuss the experimental results of tire stiffness with air and nitrogen. Tire stiffness of Tata Nano car with size P135/70R12 is tested on test rig for air and nitrogen and compared for various loads. Primarily load deflection simulation of Tire is done on Ansys software and validated with experimental result for air and then other tests are performed. Optimized tire stiffness is obtained for minimum amplitude of vibration.  Cite this Article P.A. Narwade, C.R. Shah, P.Y. Mhaske. Experimental Determination of Tire Stiffness using Nitrogen.
