Optimal Synthesis of the Planar Compliant Mechanism Using ICA Algorithm

Due to the flexibility of the compliant mechanisms (CMs), they are utilized to perform mechanical. From the viewpoint of performance, CMs have some advantages over traditional ones, such as higher precision, integrated design, and lower manufacturing costs. These flexible mechanisms have wide applications such as sensor, gripper, parallel mechanisms, MEMS, high-precision devices and biomedical and surgery robots. Topology optimization or extracting the optimal design of the planar parallel compliant mechanisms using the imperialist competition algorithm is the main novelty of the current study. Furthermore, the genetic algorithm method was used for validation. The optimized CMs that consist of beam elements are analyzed with the finite element method. The goal of this design is to maximize the mechanical advantage and the geometrical advantage. The results show that use of the imperialist competition algorithm for this problem has led to a significant improvement (20 to 30 percent) over the results from similar articles. In addition, the comparison of the two algorithms used shows that ICA performs better than the GA, which is one of the most powerful methods in optimization.
