The optimization of compliant mechanisms is a burgeoning area of research aiming to enhance the performance of mechanisms relying on flexible components. Scholarly works emphasize diverse optimization techniques, including topology optimization, shape optimization, and material selection. These methods aim to improve compliance, maximize efficiency, and reduce weight, crucial considerations in applications such as robotics and aerospace engineering. Notable studies underscore the efficacy of optimization in achieving superior designs, providing valuable insights for advancing compliant mechanisms' capabilities in various technological domains. Skeletal models such as frames have different pattern for transferring loads compared to continuum models. In this study, a methodology is proposed for topology, shape and connectivity optimization using frame model with flexible joints. Structural analysis utilizes a frame members with semi-rigid connections at both ends of the member. Cross-section sizes of members, joints coordinates and fixity factors of the connections are optimized to give the desired objective. The proposed approach is performed on various benchmark examples from the literature [1]. Preliminary results show similarity between optimized designs obtained from continuum and frame models. Further applications and computational challenges will be discussed in detail.
