| Abstract: | The measurement principle and method of side force of SRM were introduced by using magnetic suspension test fixture. Based on side force static calibration test, the current-stiffness coefficient and displacement-stiffness coefficient in the electromagnetic force calculation formula were identified. The static characteristics of magnetic suspension test fixture were verified. Linearity, hysteresis and repeatability are all equal to or less than 5% ,and comprehensive error is equal to or less than 8.7%. The data processing results of some solid rocket motor test show that side force value can be accurately measured by magnetic suspension test fixture. |
