abstract

in this article, rubber bumpers of double - wishbone suspension system have been modeled and analyzed. the objective of the present work is to predict the performance of these products during deformation, represent an optimum method to design, obtain stiffness characteristic curves and utilize the results in the automotive suspension dynamic analysis. these parts are nonlinear and exhibit large deformation under loading. they have an important role to limit the motion of wheels and absorb energy. in this study, nonlinear fe model using abaqus software was used to obtain the bumper load - displacement curve. then a laboratory test was done on the bumper to get this curve. the comparison between numerical and experimental results shows a good adaptation. a less than 2 percent difference has been observed between them. thus, we can use this numerical method to simulate bumpers easily and accurately.

On the Corotational Beam Element Formulation in Large Deformation Analysis

This paper sheds more light on the co-rotational element formulation for beams with uniform cross-section. The co-rotational elements are commonly used in problems in which a structure undergoes a large deformation. In this study, the foregoing element obeys the Euler-Bernoulli beam assumptions. Unlike the formulations presented in the literature, in this paper, a number of local nodal coordina...
