本文主要介绍了火炸药摩擦感度仪高精度摆角控制的电液实现，在原装置主体结构不变的前提下，设计了计算机控制的电液系统，实现摆锤的自动提升，并用光电编码器实时检测摆捶的提升高度，实现了摆锤高度的自动控制，为提高火炸药摩擦感度仪的精度和自动化打下了基础。
This paper mainly introduces the electro-hydraulic realization of the high precision swing angle control of the dynamite friction sensitometer. Under the premise of the same structure of the original device, the computer-controlled electro-hydraulic system is designed to realize the automatic lifting of the pendulum and real- Detecting pendulum hammer to enhance the height of the pendulum height to achieve automatic control, in order to improve the dynamite friction pyrometer accuracy and automation laid the foundation.
