An engine suspension test bench, method, device and storage medium

By designing an engine mount test bench, the vibration response of the entire vehicle can be simulated before the prototype is installed on the vehicle. This solves the problem of discovering and reproducing abnormal noise from the engine mount, shortens the verification cycle, and ensures the development progress of the entire vehicle project.

AI Technical Summary

Technical Problem

Existing technologies are insufficient to detect and reproduce engine mount noise problems before the prototype is installed in the vehicle, resulting in the noise problem being discovered too late and the improvement of prototypes and subsequent verification cycles being too long, which cannot guarantee the development and delivery schedule of the vehicle project.

Method used

An engine mount test bench was designed, including a vibration table, a support buffer and a vibrator. It simulates road vibration by in-phase or out-of-phase excitation, and realizes six-degree-of-freedom random motion of the mount by combining a controller and sensors to simulate the vibration response of the whole vehicle.

Benefits of technology

Bench testing shortens the verification cycle, ensures the comprehensiveness and accuracy of testing, and enables the early detection and reproduction of suspension noise issues, reducing development risks.

Abstract

The embodiment of the present application provides an engine suspension test bench, method, equipment and storage medium, comprising: a vibration table for restraining and installing an engine and suspension to be tested; a support buffer arranged below the vibration table, used for supporting the vibration table and the engine and suspension to be tested, so that the vibration table and the engine and suspension to be tested are in a suspended state; an exciter arranged on opposite sides of the vibration table, the exciter being used for driving the vibration table to vibrate when in-phase excitation or anti-phase excitation, so as to simulate road vibration; and a controller connected with the exciter, used for in-phase excitation or anti-phase excitation of the exciter. Through the test of the bench of the embodiment of the present application, the vibration performance similar to the road surface can be simulated, the risk assessment and abnormal sound problem reproduction function of the suspension abnormal sound are realized, so that the verification period is shortened and the comprehensiveness of the test is ensured.
