Modal analysis mainly studies the dynamic characteristics of the system in the frequency domain.Based on the theory of modal analysis,this paper conducts solution analysis of the modal shape with the single degree of freedom and multiple degree of freedom based on MATLAB,then uses Inventor to model the shoulder joint of the mechanical arm,analyzes its modal and frequency response by means of command line input,and obtains the first six modal parameters,so as to avoid the resonance phenomenon of the shoulder joint in the working process,and de-termine the scope of safe work.This paper analyzes how to use MATLAB for computational mode analysis by ex-amples,so as to provide models and reference for the establishment,optimization design and fault diagnosis of related models.
