Optimization Design of Two Dimensional Vibrating Platforms Using Dual Flexure Hinge Structure
In this paper, a 2-D vibrating platform is designed using dual flexure hinge structure and four significant structural parameters are optimized with the integrated model of Abaqus and Isight so as to improve the platform performance. The natural frequency is increased from 496.3 Hz to 2360 Hz after optimization while the distance of travel and the stress satisfy the constrains. The optimization results are confirmed with the test data. The optimized 2-D vibrating platform is applied into the micro milling and the machined surface quality is improved. Therefore, the optimized 2-D vibrating platform is a valid equipment to carry out 2-D vibration-assisted micro milling and study the cutting mechanism.
