Dimension optimization analysis and verification of parallel antenna mechanism
The dimension optimization design of antenna mechanism is an important procedure in the development and engineering application of antennae.The bearing capacity and the motion range of the actuation branch are proposed as the dimension optimization objectives of the parallel antenna mechanism.The dimension optimization analysis is carried out based on the parametric design module.Firstly,the structure of the parallel antenna mech-anism is described,and the kinematic model of the mechanism is established.Then the design variables,objec-tive functions and constraints of the mechanism are defined according to the working requirements of the antenna.The parametric model of the mechanism is established by using the optimization design module of Adams.Sec-ondly,the influence of design variables on the objective function is studied.The mechanism scale parameters with excellent comprehensive performance are obtained.Finally,according to the dimension optimization results,the antenna prototype is developed and experimental research is carried out.The experimental results show that the antenna prototype can achieve the expected motion without interference.The research work provides a refer-ence for the optimal design and prototype development of parallel antenna mechanism.
