一种高精度测量坦克炮塔动态转角的方法

High precision angle measurement method of dynamic tank turret

坦克炮塔相对底盘转角的测量精度直接决定了稳瞄系统与惯导系统的精度。目前,国内的主战坦克所配备的坦克炮塔,其相对底盘的转角测量装置的测量精度低,仅解决坦克车体的转向问题。针对稳瞄系统与惯导系统对坦克炮塔相对底盘转角的精度要求问题,提出了一种由光电定位系统、机械传动系统和旋转变压器组成的动态高精度测角装置,介绍了其工作原理和工作过程,对该测角装置进行光电自准直标定并对误差进行理论分析,最后通过上车实验证明该测角系统能够满足实际需求。实践证明:该测量系统能够在通电瞬间确认位置,具有绝对零位记忆功能,其测角精度为42″。

Tank turret rotation angle measurement accuracy relative to the chassis directly deter- mines the precision of the stable sighting system and the inertial navigation system. At pres- ent, the main battle tank equipped with a tank turret in the angle measurement device which has low measurement accuracy relative to the chassis can solve the problem of steering the tank body only. This paper proposed a high-precision angle measurement device which was com- posed of location and orientation system, mechanical drive system and resolver. It firstly intro- duced the working principle and work process, followed by the angle measuring device calibra- tion and the theoretical analysis of error, the final joint commissioning proved this angle meas- uring system met the actual demand. Results indicate that this measurement system can con- firm the location when instantaneously powered and has absolutely zero memory function, the angular accuracy is 42＂.
