The Finite Element Analysis

This paper is focused on the finite element analysis (FEA) and theoretical calculation of vibration characterization of V-shaped electrothermal microactuator. A vibration mechanical model about V-shaped electrothermal microactuator is presented. By having a comparison between FEA and theoretical calculation about natural frequencies of V-shaped electrothermal microactuator, the maximum error is within 0.19 %. This paper also analyzes the influences of microactuator geometric parameters on natural frequency. The length and thickness have larger effect on the natural frequency of the actuator, while the angle and width have less effect on the natural frequency.

Calculation Results

Dynamic performance of high speed dynamic balancing machine directly affects the accuracy and safety of dynamic balancing machine. ANSYS 12.0 was used to establish the frame structure model in this paper. The four models of dynamic balancing machine were calculated respectively. The calculation results show that additional stiffness can greatly improve the natural frequencies of dynamic balancing machine. In addition, as the base is large, we can ignore the influence on natural frequencies caused by the base.
