Measurement Device Design for the Projectile State Parameter Testing

针对弹药自动装填系统运行状态监测的需求,研究了弹药自动装填系统运行时会影响到的弹丸各状态参数,根据测试原理与测试指标要求,设计了弹丸振动加速度和角速度存储测试装置。选择了合适的传感器与主控芯片,设计了相应的信号调理与A/D转换、存储和通信模块;设计了下位机采集、存储和通信模块;根据数据处理的需求,利用Lab VIEW设计了人机交互与数据处理、分析软件。最后,通过弹药自动装填系统实车测试实验,对设计的存储测试装置进行了性能验证。结果表明,设计的存储测试装置能够测量出弹药自动装填系统运行过程中的状态参数变化,可以作为弹药自动装填系统特性研究的测量工具。

According to the requirement of the ammunition automatic loading process testing,this paper studied the changes of the projectile when the automatic loading system is running. According to the test principle and the test target,we designed a storage test device to test the acceleration and angular velocity of the projectile. In this paper,we selected a suitable sensor and control chips and designed the corresponding signal conditioning module,A / D conversion module,storage module and communication module. Then,we designed the software for data collection and processing. Finally,the property of the storage test device was verified through the test experiment on the automatic ammunition loading system.Results show that this test device can measure out the changes of the projectile when the automatic loading system is running. This device can be used as a measurement tool for the test of automatic ammunition loading system.
