【摘要】 试射是武器精度检验中的一个重要环节,而武器射效是人—枪相互作用的结果,为了能够排除射手的主观因素客观地检验武器本身的性能,从而提出建立能够模拟理想的“标准射手”的装置,即“模拟人体枪架”。前人研究的被动态“模拟人体枪架”适用于连续射击射弹数较少的情况,但当射弹数较多时,人体的主动反应将会对射击精度产生显著影响,因此研究主动态“模拟人体枪架”具有重要意义。本文对主动态“模拟人体枪架”的控制系统进行了探索性的研究,完成了主动态“模拟人体枪架”控制系统的总体设计、硬件设计和软件设计,并对控制系统进行了调试。首先通过“模拟人体枪架”的功能分析,提出了控制系统的实现策略与设计步骤,完成了控制系统的总体方案设计。其次选择单片机为主控芯片,伺服电机为执行元件实现了控制“模拟人体枪架”运动的要求;选择合适的测量元件实时测量“模拟人体枪架”的运动状态,并通过单片机与上位机的串口通信将测量数据传输给上位机处理。采用模块化和结构化的思想编写了程序,支持硬件实现主动态“模拟人体枪架”控制系统的功能。最后调试、运行了控制系统,并通过与真人射击数据的比较,验证了本控制方案的可行性。本文的研究成果,对进一步研究主动态“模拟人体枪架”具有一定的参考价值和指导作用。更多还原

【Abstract】 Shooting test is a very important process in weapon accuracy inspection, and weapon’s firing effect is the result of the interaction between shooter and weapon. In order to exclude the subjective factors of the shooter and check the weapon objectively, a device that can simulate the ideal "standard shooter" has been proposed, which is also called simulative body gun-frame.The passive state simulative body gun-frame studied by former researchers only aims at the circs of fewer shootings. But when it is used in the circs of more shootings, shooter’s active reaction will generate significant effect on shooting accuracy. Therefore it is very important to research the active state simulative body gun-frame.The explorative researches to the control system of the active state simulative body gun-frame have been conducted. The overall design, hardware design and software design of the control system of the active state simulative body gun-frame were carried out and the control system was also debugged. First, the implementation strategy and design steps of the control system were proposed based on the functional analysis of the simulative body gun-frame and the overall scheme design of the control system was conducted. Then, MCU was chosen as the main control chip and servo motors as the actuators to realize the control requirement of simulative body gun-frame. The suitable measuring elements were selected to complete the real-time measurement of motion state of simulative body gun-frame and transmit the measured data to the upper computer by serial communication of MCU and upper computer. With modular and structured idea, the program was completed to support the hardware system. Eventually, the control system was debugged and operated and the feasibility of the control system was verified by comparing with the shooting data fired by shooters.The accomplished results are of great importance for further studies of the active state simulative body gun-frame.更多还原
