Design and Accuracy Analysis of Lifting Mechanism for Radar Antenna

Abstract：This paper proposes a new type of antenna lifting mechanism for mobile radar on vehicle， which adopts a cylinder barrel integrated design and can effectively achieve miniaturization and lightweight of the mechanism. And its drive and transmission employs the combination form of servo motor， reduction mechanism， and mechanical two-stage synchronous ball screw. The load and accuracy of the lifting mechanism is further analized. The NX simulation and experiments verify the high accuracy， high stiffness and high strength of the proposed lifting mechanism.

Keywords：mobile radar antenna; lifting mechanism; cylinder barrel integrate; load analysis; accuracy analysis
