Abstract: Firstly,the work principle of the two-axes position mechanism for(satellite) antennas is indicated.A solid model of the two-axes position mechanism is built based on the(analysis) and simplification to the system.Then,the method of building the virtual prototype model based on the solid model is brought forth.Finally,the simulation results and the deep-going(analyzing)(conclusions) are showed,which provided the useful suggestions to the optimal design of the physical prototype of the two-axes position mechanism for satellite antennas.
