Structural Modal Analysis and Optimization Design of Dimension Measurement Equipment

The dimension measurement equipment is inevitably accompanied with vibration during its operation process, so it is particularly important to study its modal analysis. In the paper, the structural modal analysis of the dimension measurement equipment was conducted, and the first six orders natural frequencies and vibration were computed. In addition, the probable resonance risk and design hidden troubles were pointed out. The method of optimization was determined by combining the results of modal analysis with the engineering experience. By comparing the results of modal analysis before and after optimization, the first natural frequency is increased by 18.9% after optimization, which offers references for the design and manufacture of the dimension measurement equipment.
