Abstract

For example of the two-degree-of-freedom micro-actuator, the topology optimization, extraction and experiment are investigated. Firstly, the topology optimization model considering the suppression strategy of input and output coupling terms and optimization algorithm is developed. Secondly, according to the specific characteristics of compliant mechanisms, a topology extraction method is presented, which includes image preprocessing, boundary extraction using the density contour method, and geometric reconstruction. Finally, based on the topology mechanism and the restriction of fabrication technology, the prototype of the two-degree-of-freedom micro-actuator is determined. The prototype is fabricated by means of linear cutting technology. The displacements of the two-degree-of-freedom micro-actuator are measured by using the control system. The experimental results show that properties of the two-degree-of-freedom micro-actuator can satisfy the designing demand and this approach available.
