针对目前在悬挂发射装置地面投放试验中利用力传感器测量弹射力的方法(简称电测法)存在的不足和局限性,提出了一种采用光学手段测量悬挂发射装置弹射力的方法(简称光测法)。该方法基于高速摄像装置,经过对高速图像的处理,获得投掷过程相关的位置变化数据,并根据内在物理规律推导出投掷物分离时的受力情况。对上述2种方法通过地面试验进行了对比测量分析,结果证明了用光测法代替电测法的可行性和优越性。
Aiming at the shortcomings and limitations of the method of measuring the ejection force by force sensor in the ground launch test of the suspension launcher (referred to as the electric measurement method for short), a method for measuring the ejection force of the suspension launcher by optical means is proposed law). Based on the high-speed camera, the method obtains the position change data related to the throwing process after the high-speed image processing and deduces the force condition when the object is separated according to the inherent physical laws. The above two methods through the ground test conducted comparative measurement and analysis, the results show that the use of optical measurement method instead of the feasibility and superiority.
