Modal Calculation Applied in the Study of Vehicle Cab through Fluid-Structure Coupling Model

Abstract

The main research indexes of commercial vehicle NVH performance include cab modal, sound cavity modal, fluid-structure coupling modal and so on. With the NVH performance of commercial vehicles more and more attention by the host enterprises, based on the modal theory, this paper studied the modal of the commercial vehicle cab, according to the cab modal, fluid-structure coupling model, established a set of commercial vehicle cab model evaluation method.
