    Abstract

    This research presents a structural topology optimization method for the design of mechanical resonators, and smart structures, such as mechanical actuators and sensors, that are composed of flexible structures and mechanical energy conversion devices. First, the concept of the topology optimization method is briefly discussed. Next, we clarify the mechanical design specifications of mechanical resonators, actuators and sensors, and construct objective functions that aim to satisfy design specifications. Based on these formulations, an optimization algorithm is constructed using Sequential Linear Programming (SLP). Finally, several numerical examples are presented in order to confirm that the method presented here can provide optimized structures applicable to the design of mechanical resonators, mechanical actuators and sensors.
