Abstract
In this paper, the influence of the geometric parameters of a thrust measurement stand in mN level and for electrical thrusters on its performance is investigated. To measure the thrust of the electrical thrusters, a system must be used that separates the thrust force from the weight force. Thus, thrust measurement systems are designed based on a pendulum. The geometric parameters of a thrust measurement stand, such as the length of arms, the mass of different parts, and the stiffness of pivots affect the overall performance of the system, including its dynamic and static response (for example, displacement, natural frequency and stabilization time of oscillations). For this purpose, primarily, the analytical model for the behavior of a thrust measurement stand with an inverted pendulum configuration is obtained. Then, using the obtained results, the optimal design of several stands is carried out based on the specified physical requirements and using the Genetic Algorithm method. Finally, an experimental thrust measurement stand with a maximum measuring thrust of 100 mN is developed based on obtained specifications from the optimization and by validating the results of the analytical model, the error of the model is estimated to be less than 6 percent.
