Parallel type six-freedom-degree redundant driving antenna structural system

Abstract

Disclosed is a parallel type six-freedom-degree redundant driving antenna structural system. The parallel type six-freedom-degree redundant driving antenna structural system comprises an antenna reflective surface and an antenna pedestal, wherein the antenna reflective surface is linked on the antenna pedestal; the antenna pedestal comprises a fixed platform and a movable platform which are arranged in parallel; the fixed platform is a convex circular table with gradually decreased caliber; three groups of guiding rail units are uniformly distributed on the fixed platform; each guiding rail unit group consists of two guiding rails; each guiding rail is equipped with a driving sliding block; a telescopic unit is hinged on each driving sliding block in a one-to-one correspondence manner; all the telescopic units are hinged to the movable platform; each movement point can perform coordination action by following four movement units, so that special forms and positions can be effectively reduced; the convex circular table shape of the fixed platform is matched with the driving sliding blocks to realize overturn of the antenna; the multiple driving sliding blocks are matched with the telescopic units to perform a coordination operation, so that not only all-around tracking of the antenna, but also negative angle pitching of the antenna can be realized; and consequently, the stability, flexibility and rigidity of the mechanism are highly reinforced.

Description

technical field [0001] The invention belongs to the field of ship-borne antenna devices, and in particular relates to a parallel six-degree-of-freedom redundant driving antenna structure system. Background technique [0002] The antenna pedestal is the support and orientation device of the antenna, which is used to enable the antenna to accurately point to the target according to the predetermined trajectory or follow the target movement, and quickly and accurately follow the target movement. Its structure affects the whole antenna to a large extent. performance indicators. [0003] With the continuous development of antenna technology, especially the rapid development of mobile carrier antenna equipment, the performance requirements for antenna equipment such as rotational angular velocity, angular acceleration, accuracy, stiffness, reliability, and dynamic characteristics are increasing, while the performance indicators of traditional antenna bases It has become increasin...
