Modal Test and Analysis of Dump Truck Frame

Liu Da

Abstract

This paper is to solve the lateral vibration of a dump truck.Testing modal analysis techniques were applied to analyze dynamic characteristics of the dump truck frame.The modal frequencies,modal damping and modal shapes were obtained using testing modal analysis.The results from modal analysis show the stiffness of the front part of the frame is weak and the frame reveals lateral vibration when the excitation frequencies are 5.75 Hz and 10.36Hz.Modal test and analysis of dump truck frame provide reliable information for analyzing the NVH of the dump truck and optimizing the design of the dump truck frame.
