Vibration Characteristics of the Automotive Rearview Mirror

Abstract Vibration performance is a critical factor in the design of automotive rearview mirrors. Because of the complexities involved in the structure of the rearview mirror, its mounting location on the vehicle and its operational conditions, design optimization from finite element analysis is a necessary procedure in order to obtain good vibration response and reduce costs. This paper summarizes the results for design optimization and material selection from finite element analysis (FEA) conclusions. The finite element analysis results indicated that design optimization is very important in the final performance of part vibration and deformation. For design innovations that reduce parts count, decrease costs, and preserve or improve product quality, it may be a critical factor to utilize higher performance composites in place of more traditional materials. Several materials are studied with regard to their properties and dynamic performances. The results could help to achieve cost reduction in part design and to obtain design optimization for current and future programs.
