摘要大口径自行火炮的核心部分弹药自动装填，它的性能决定了数字化火炮现代化水平的高低。本文是以大口径自行火炮自动装填系统中的弹药传输机械臂为研究对象，并经过简化后得到存在基础振动的机械臂系统，结合实际输出控制端，加以具体的实施控制方案，很好的仿真模拟了弹药传输机械臂响应外部随机激励的控制过程，为今后改善弹药自动装填理论提供了一定的基础。
在本文中，我们首先介绍了包括机械臂、电机、增量式编码器、电机控制器和减速箱在内的单自由度机械臂机电系统，建立了该机电系统的三文模型，结合该系统控制图对电机驱动下的机械臂机电系统进行ADAMS与MATLAB联合仿真，在无基础振动和存在随机基础振动两种不同的情况下进行了仿真分析，证明随机基础振动对机械臂的动态特性具有十分重要的影响。26387

Title A Modeling, simulation and Control Research of the mechanic arm with basic vibration happening
Abstract
The core part of large-caliber artillery ammunition can do self-loading, and its performance determines the level of artillery modernization level of digitization. This article is targeted on large-caliber self-propelled artillery ammunition transmission arm with automatic loading system, and shows a vibration manipulator system after being simplified . Combined with the actual output control , the actual implementation of control program provides a good simulation of ammunition transport arm in response to external random excitation control process,which provides a foundation for improving the self-loading ammunition theory .
First of all,this article talks about the mechanical and electrical systems including single DOF manipulator arm, motor, incremental encoder, the motor controller and gearbox, including the establishment of a three-dimensional model with single degree of freedom.Using ADAMS and MATLAB to simulate the electric and mechanical systems in two different situation: the presence of random vibration-free foundation existing or not ,we can prove that basic vibration has significant impact on the dynamic characteristics of the robot arm.
Keywords：large-caliber self-propelled artillery ammunition transfer arm single degree of freedom arm random basic vibration
