ABSTRACT
This paper describes the hardware design of the multi-parameter signal generator, including the mechanical system and measuring and control system. The required functions of the instrument are well realized, which can generate reliable signals for tests and control, and the operation of the instrument is simple with a high level of automation and methods of protection.
The whole system operates steady and credible with the reasonable design of the mechanical system. A PLC is used as the core of control. With the help of driving system and multiple sensors, the PLC operates the whole system in coordination. Not only does the PLC control the motions of the mechanical part, it also conveys the multi-parameter signal for analysis. By modulating the speed of the stepping motor, the way of motor-control in altered frequency is well realized, which meets the need of rapidity and steadiness. The monitoring function, along with the debug program, provides the possibility that the running condition and the inner coherence of the program can be shown to the user in time.
After debugging and rectification several times, the whole is reliable and steady and well functioned.
Keywords: multi-parameter signal generator, mechanical design, PLC stepping motor, altered frequency

1. 绪论
1.1 概述
多参数信号发生装置，可以模拟多种物理参量的产生，从而对信号采集、机构动作控制等过程进行模拟和实际控制操作。撞击感度仪，作为研究炸药感度的装置，主要的原理是：利用不同质量的落锤，通过高度提升装置，从不同高度释放后，以自由下落的方式撞击炸药试样，进而检测所产生的多种信号，以表征炸药的爆炸的难易程度，科学的衡量了炸药的安全可靠性。
