The series elastic component is the most critical component of the Series Elastic Actuator (SEA), which directly determines the performance of the SEA. SEA can ensures the safety of the operator during human-robot interaction to a certain extent. In this paper, we use the topology optimization method to design the series elastic component. In order to make the series elastic component have large torsional compliance and high precision, the weighted sum of torsional compliance and radial stiffness is used as the optimization objective function, and a general model of the topology optimization of the series elastic component is established. The numerical examples are used to verify the correctness and effectiveness of the optimization model. According to the results of topology optimization, a new type of high-precision series elastic component is designed, and the accuracy of the model is verified by finite element simulation, which is compared with the traditional series elastic component.

In this paper, the topology optimization method is introduced into the design of series elastic component, which expands the design space of series elastic component, enriches the types of configurations, and provides feasible ideas for the design of series elastic components.
