摆动喷管控制精度相关问题讨论

对不同性质的喷管特点以及在控制力作用下喷管的响应特性进行了初步分析;以某防空导弹为例,阐述了摆动喷管在非理想状态下摆动时作动器牵连运动、正负摆角不对称、力臂变化、摆心漂移、位移传递系数精度和预调角对摆角控制的影响;同时说明了负载力矩和伺服机构相关参数影响着摆动喷管位置控制精度。

Discussion on Control Precision of Single Swing Nozzle

The characteristic of different kinds of nozzles and responses of nozzles under the influence of control force are introduced.As an example of one kind of antiairoraft missile,some factors influencing the control of swing angle in real conditions as the coupled motion of cylinders,the unsymmetry of swing angle,the variation of the arm of force,the excursion of swing center,the precision of placement transfer coefficient and the initial angle are expatiated.Furthermore,the load-torque and the coefficients of servo-actuator are presented.
