| 摘 要： | 弹丸速度和位移的测量是电磁炮重要的测试项目之一。针对以往分布式探针测速需要多路高速采集通道的问题，提出采用探针串联和波形叠加进行增强型电磁轨道炮膛内电枢速度测量的两种新方法。通过仿真给出采用驱动电流信号和拟合速度变化曲线计算增强型电磁轨道炮磁探针感应电压的方法；通过实验分别采用探针串联和波形合并两种新方法对膛内电枢速度进行测量，并与分布式测量方法进行比较。仿真和实验结果表明：仿真所得探针波形与实验测得的波形基本一致，提出的两种新方法与分布式测量方法相比只需要一路高速采集端口，具有成本低、可靠性高等特点，为轨道电磁炮膛内电枢速度的测量提供了一条新途径。弹丸速度和位移的测量是电磁炮重要的测试项目之一。针对以往分布式探针测速需要多路高速采集通道的问题，提出采用探针串联和波形叠加进行增强型电磁轨道炮膛内电枢速度测量的两种新方法。通过仿真给出采用驱动电流信号和拟合速度变化曲线计算增强型电磁轨道炮磁探针感应电压的方法；通过实验分别采用探针串联和波形合并两种新方法对膛内电枢速度进行测量，并与分布式测量方法进行比较。仿真和实验结果表明：仿真所得探针波形与实验测得的波形基本一致，提出的两种新方法与分布式测量方法相比只需要一路高速采集端口，具有成本低、可靠性高等特点，为轨道电磁炮膛内电枢速度的测量提供了一条新途径。

| Abstract: | The measurement of projectile velocity and displacement is one of the railgun test parameters. The multiple high-speed data acquisition channels are required in the velocity measurement of distributed probes. The new probe in-series and waveform combination methods for measuring the velocity of solid armature in enhanced electromagnetic railgun bore are proposed according to the velocity measuring principle of the B probe. The induced voltage of the probe of enhanced electromagnetic railgun is calculated by using the driving current data and the fitting speed data, and then the probe in-series and waveform combination methods are used to measure the armature velocity, respectively. The simulation and experimental results show that the calculated waveform is basically in agreement with the measured waveform. The proposed methods are compared with the distributed probe measurement method. The two methods need only one high-speed data acquisition port. They have the advantages of low cost and high reliability. |
