Dynamic and Static Characteristics Analysis for Flexible Assembly Cell

Abstract

A flexible assembly cell has been designed for precision microstructures. In this paper, the static analysis and dynamic characteristics of the assembly cell are analyzed respectively. Through the finite element static analysis and simulation, we optimized the assembly cell’s structure design. Through the modal analysis, the first six nature frequencies and nature mode shapes are obtained. The overall oscillation of the first two sections, shows that the asssembly cell has a better dynamic performance. Meanwhile a modal test on assembly cell structure was also conducted. The first-order natural frequency has been obtained. The critical rotating speed is much higher than the maximum speed of the motor in the assembly cell, and no resonance phenomenon can be generated. The simulative results are consistent with the experimental results, and the correctness and adaptability of the simulation method are verified, ensuring the accuracy and reliability of the assembly cell.
