设计简介
本课题是一个具有鲜明的工程背景的课题。在某型集束弹药基础上，设计出一种静态地面模拟试验装置（采用带传动机构），该模拟炮试验装置主要由步进电机、主旋转轴、轴承、皮带轮传动机构、弹簧机构、子弹以及底座等组成。由步进电机驱动器控制步进电机以一定的转速旋转（转速可由步进电机控制器调节控制），通过皮带轮带动主转轴旋转，由转速测量仪读出转速，当转速稳定在1500r/min的转速时，旋转操作轮盘，释放弹簧，弹簧力将爆炸单元抛出，整个抛射过程完成，炮弹部分是靠主轴的旋转带动炮弹旋转。该装置可实现“子弹”出膛初速度为20m/s、飞行距离实现10m的要求，本文的研究结果，实现了预期目标，对该型集束弹药的工程研制具有重要的参考价值。

Abstract
This issue is a clear engineering background task. In the basis of a certain type of cluster munitions, to design a static ground test equipment (with belt drive mechanism), the simulated gun test device consists of stepper motor, the main rotating shaft, bearings, pulley drive mechanism, spring mechanism, bullets and base and other components. Controlled by the stepper motor driver stepper motor to a certain rotation speed (speed of adjustment can be stepper motor controller, control), the main shaft through the drive pulley rotating by the rotation speed meter reading, when the speed steady at the speed of 1500r/min When wheel spin operation, the release of the spring, the spring force will throw explosive unit, the ejection process is complete, shells partly driven by the rotation axis rotating shells. The device can achieve a "bullet" shell leaving the initial velocity is 20m / s, 10m flight from achieving the requirements, the results of this study, to achieve the desired objectives, the type of cluster munitions engineering development has important reference value.
