英文摘要：

The mechanical structure of attitude measuring device for guided ammunition is able to resist the high overload and high impact, which is the precondition of the attitude control and precision guidance. In view of the ex- isting attitude measuring device mechanical structure＇s pool anti overload ability, complex structures,we put forward a mechanical structure of high overload attitude measuring device which has the advantages of simple structure, high mechanical strength and strong overload capacity. The high overload attitude measuring device includes a battery u- nit, a signal processing circuit, three bell vibrator, a base and a housing. The corresponding parameters and structures were optimized with the computer aided engineering simulation method in the mechanical structure design, and the space was utilized reasonably. By using a high temperature and high impedance mixed glue and layered embedding technology,the anti overload performance of the structure was significantly improved. The finite element simulation proves that the proposed high overload attitude measuring device mechanical structure can resist over 20000g. Func- tional tests have proved that the mechanical structure can meet the measurement of the attitude of the complex and high overload environment.
