A linear actuator with mechanical synchronous lifting driven by a single motor is proposed, which achieves synchronous telescopic motion of the master/slave push rod. Firstly, the overall structural scheme of the linear actuator was designed to meet the practical application requirements of the vehicle radar system. Secondly, the corresponding parameters of the linear actuator were calculated based on theory, and the motion characteristics and force state were simulated and analyzed using finite element software. Finally, the synchronization accuracy of the linear actuator telescopic motion was calculated in detail and verified through an actual case. The results indicate that the high-precision mechanical synchronous linear actuator has higher synchronization, reliability, and safety advantages compared to hydraulic synchronous linear actuator and dual motor synchronous linear actuator, and has good reference significance in the same industry.
