Topology optimization and control of rotating compliant mechanism

This paper propose the algorithm of design and control rotating compliant mechanism through topology optimization. Triangles elements are adapted to solve complex design region and reduce effectively appearance of zigzag boundary of optimal topology of mechanism. Many benchmark problems have been tested to verify the mathematical formulation and solving approach. The triangle micro-gripper illustrates that this algorithm is effective to muti-connected design region. The established method is applied to rotating compliant mechanisms of triangle micro-gripper and distortion actuator and get good topology, and can achieves very good results. The circumferential distortion actuator are composed of six same compliant mechanisms, the resultant topology is simple, clear and easy to manufacture and assembly. Numerical computations show kinematics behaviors of the mechanism can be controlled as expected easily. This paper gives the conceptual model design algorithm through topology optimization and as a further application it can be applied to design of more complicated compliant and/or rigid mechanism.
