Abstract
Anti-roll bar is a suspension component used at the front, rear, or at both ends of a car that reduces body roll by resisting any uneven vertical motion between the pair of wheels, to which it is connected. Modeling accuracy for anti-roll bar is very important for vehicle dynamics analysis because of large deformation induced by suspension motion. There are two modeling methods commonly used in multi-body dynamics software (ADAMS). One is a standard modeling method provided by Adams software, named nonlinear beam method. The other one is a three dimensional flexible modeling method through the interface provided by ADAMS and finite element software such as NASTRAN etc. In order to satisfy the requirements of vehicle dynamics performance, a lot of similar and repetitive modeling work must be done in automobile suspension development stage due to design changes, such as diameter of anti-roll bar, etc. Therefore, it is necessary to develop simpler and more efficient modeling method for anti-roll bar to satisfy the product development cycle.
In this paper, a practical modeling method for anti-roll bar is developed by using component mode synthesis method based on one dimensional finite element method. It is simple, efficient, easy to adjust and has high simulation accuracy for dynamics analysis using ADAMS, as compared to traditional nonlinear beam method and three dimensional flexible body modeling method.
