This paper describes a method for verifying vehicle performance when applying a new suspension bushing at the concept phase of vehicle development. At the concept phase, it is difficult to obtain the nonlinear characteristics of the bushing, which plays an important role in the performance of the vehicle. Thus, a tool to design bushing has been developed.

A method that designers can intuitively and easily design a bush is proposed. It combines the results of the developed bushing design tool with a Modelica system model to evaluate NVH, R&H, and durability performance. Designers can create a new bushing using the bushing design tool and check the vehicle performance at an early stage of development process. The developed bushing design tool allows designers to evaluate vehicle performance by reflecting bushing characteristics without actual products.
