Abstract

As the core component of Concentrator-Splitter Optics System, the beam splitter has an important influence on solar energy utility efficiency improvement. The vibration frequency of beam splitter fixed structure caused by external stimulation has great influence on system accuracy. So, it is necessary to analyze the natural frequency and its model shapes.This paper describes the finite element modal analysis theory briefly, establishes analysis model structure of the fixed structure by ABAQUS, obtains each vibration mode shape and its corresponding natural frequency. Finally, we optimize the mechanical structure according to the numerical analysis results and propose a method that install rubber shock pad between the system and protective box to decrease the external stimulation influence on system accuracy. This work has a reference value to ensure the solar energy utility efficiency of the system.
