【摘要】：固体火箭发动机,在航空航天领域中应用广泛,具有重要的战略意义。我国在固体火箭发动机推进剂配制和型腔设计方面处于国际领先水平,但制造固体火箭发动机的设备自动化水平不高,工艺装备落后,研制自主知识产权的自动化装备势在必行。整形是发动机制造过程中的一个重要步骤,直接决定药柱内型腔的最终形状。长期以来,我国固体火箭发动机的整形基本靠手工完成,生产效率低,易产生过切等严重后果。研发自动整形装备,不仅可以提高生产效率和加工精度,还可以保护工人人身安全,减少新型发动机研制过程中不必要的损失。本文以固体火箭发动机整形机床为研究对象,研究了固体火箭发动机药柱安全加工工艺,完成了整形机床机械结构的设计,用Pro/E软件绘制了机床各个零件的三维图和装配图。并用AutoCAD软件绘制了机床的二维装配图和需要加工零件的二维零件图。由于火箭药柱狭长,内部加工空间有限,本机床采用了主轴可偏转机构来解决这个难题。但是当主轴偏转一定角度后,其绕自身轴线的回转速度和加速度会产生波动。为减小加工时对药柱的冲击,本文对机床的主轴部件进行了运动学分析。用Adams软件对机床主轴结构进行了运动仿真,得到了相关数据。根据设计尺寸和运动机构特点求算出了主轴机构联动公式,用Matlab软件对得出公式绘制了图像,并把数据与Adams得出的数据进行了对比。本文对机床的控制系统做了详细规划,采用以PMAC运动控制器为核心的开放式控制系统,以实现多轴联动控制和实时通讯,使用了符合防爆要求的伺服电机和各种传感器。规划了控制系统软件模块,用VC++开发了软件界面。
[Abstract]:Solid rocket motor (SRM) is widely used in aerospace field and has important strategic significance. Our country is in the international leading level in propellant preparation and cavity design of solid rocket motor, but the equipment automation level of manufacturing solid rocket motor is not high, and the process equipment is backward. It is imperative to develop the automatic equipment of independent intellectual property. Shaping is an important step in the engine manufacturing process, which directly determines the final shape of the inner cavity. For a long time, the shaping of solid rocket motor in our country has been finished by hand, the production efficiency is low, and the serious consequences such as overcutting are easy to be produced. The development of automatic shaping equipment can not only improve production efficiency and processing accuracy, but also protect workers' personal safety and reduce unnecessary losses in the development of new engine. In this paper, the solid rocket motor plastic machine tool is taken as the research object, the safe processing technology of solid rocket motor charge column is studied, the mechanical structure design of the shaping machine tool is completed, and the 3D and assembly drawings of each part of the machine tool are drawn with Pro/E software. The two-dimensional assembly drawing of machine tool and the two-dimensional part drawing of parts needed to be machined are plotted by AutoCAD software. Because of the narrow and narrow rocket charge, the internal processing space is limited, so the spindle deflectable mechanism is used to solve this problem. However, the rotation velocity and acceleration around its axis will fluctuate when the spindle deflects at a certain angle. In order to reduce the impact on the grain, the kinematic analysis of the spindle parts of the machine tool is carried out in this paper. The motion simulation of the spindle structure of the machine tool is carried out with Adams software, and the relevant data are obtained. According to the design size and the characteristics of the motion mechanism, the linkage formula of the spindle mechanism is calculated, and the image is drawn with the formula obtained by Matlab software, and the data is compared with the data obtained by Adams. In this paper, the control system of the machine tool is planned in detail. The open control system with PMAC motion controller as the core is adopted to realize the multi-axis linkage control and real-time communication. The servo motor and various sensors that meet the requirements of anti-explosion are used. The software module of the control system is planned and the software interface is developed with VC.
