Abstract

Optimization algorithms have been routinely utilized for topology optimization for vibration suppression. It is quite often necessitated that vibration needs to be suppressed at multiple locations. For this problem, conventional optimization-based approaches can be time-consuming for seeking optimal solutions resulting in iterative procedures. This is true particularly for addressing those fundamental problems such as feasibility of performance specification, performance limit, seeking sub-optimal solutions, and determining compromisability of performance at multiple locations etc. In this paper, a novel approach is proposed where all these problems can be tackled without iterative trials-and-errors. Clear-cut answers can be obtained solely based on visual inspections. As a consequence, a new design methodology is established whose powerfulness is demonstrated through its application to vehicle suspension structures.
