| Abstract: | This paper introduces a piezoelectrical quartz thrust vector measuring platform in detail,Based on the static analysis using finite element method,the structure parameters optimum design of measuring platform is carried out to reduce unlinearity and get minimal cross talk.The experimental results show that the platform has better quasistatic property index.The sensitiveness and linearity of measuring platform all can completely meet the design needs and the cross talk of the output forces is lower than 2%,and it can satisfy the need of thrust vector measurement. |
