Abstract

In active optics technology, the force actuator is a key component of the active support system. However, the existing electromechanical force actuators have difficulty ensuring the linearity of output force and have a complex structure with poor accuracy. This article addresses this issue by designing a high-precision and highly linear force actuator. The force actuator converts the linear displacement of the stepper motor driving the screw nut into the pressure of the spring through a composite spring group and achieves the output tensile and compressive forces through the preload of the spring group. According to the test results, this force actuator has high linearity, with a maximum tensile and compressive force of up to 200 N and a repeatability accuracy within 0.1 N, achieving the design goal.
