摘要
Abstract
Accelerator pedal of the vehicle is a mechanism used frequently by drivers, and its comfort is immediately related to driving safety. In this paper, the vibration of an SUV accelerator pedal was analyzed. The internal vibration test and the modal test of the vehicle on road with chassis dynamometer were conducted to analyze the excitation source, transmission path and the response. The dynamic stiffness at the installation points of the accelerator pedal was simulated by means of CAE. Some abnormal peak values were found on IPI curve, but they disappeared after strengthening the installation bracket of the pedal. The test result shows that after optimizing the bracket installation of the pedal, the vibration amplitude of the accelerator pedal is reduced by 1.4m/s2, and the vibration of the pedal disappears according to subjective evaluation.关键词
