Numerical Simulation of Dynamic Impact Test for Optimized Automobile Wheel Rim

In automobile sector wheel rim is one of the important part which are used as protection for passengers from collision. There are number of wheel test are available in designing of rim to fulfill the safety requirements and standards. The aim of this study was to analyze and study the structure for car wheel rim by using the numerical method. The most of the test procedure has to comply with international standards, which establishes minimum mechanical requirements and impact collision characteristics of wheels. Numerical implementation of impact test is convenient for shorten the design time and lower development cost. In this study cast aluminium alloy wheel rim are used for simulation of impact test by using 3–D explicit finite element methods. The design of aluminium alloy wheel for automobile application which is carried out and paying special attention to optimization of the shape and mass of the wheel rim according to aesthetical point of view, to overcome the wheel cap. A finite element model of the wheel with its tire and striker were developed taking account of the nonlinearity material properties. Simulation was conducted to study the stress and displacement distributions during impact test. The analyses results are presented as a function of time. The study is carried under the above constraints and the results are taken to carryout for further analysis i.e. shape and weight optimization of the wheel.
