【摘要】 工作面“三机”几何尺寸配套设计就是要确定采煤机、液压支架和刮板输送机的相互搭配尺寸,保证设备运行时不发生干扰,并能最大程度的发挥配套设备的性能。然而目前多采用二维图表达综采工作面设备配套,二维图既不能形象直观地反映配套情况,又不能进行动态修改,也无法解决配套过程中装配检查、干涉检查与运动仿真等问题。针对此问题本文建立“三机”的三维模型代替二维图全面地反映设备配套情况,进而可在三维模型的基础上作进一步相关的有限元分析,为综采工作面设备配套研究提供了更有效的方法。随着计算机技术的发展,设计人员在三维模型基础上又开发了新的产品设计方法—参数化设计,应用该设计方法无需重新建模,只需更改参数化模型的设计参数就可以得到新的模型,进而进行装配检查、干涉检查、运动仿真等工作,这样有效地缩短了设计周期,提高了设计质量。本课题研究的综采设备外形和结构相似,为了避免同类零件的重复建模,在UG软件的基础上,进行二次开发,完成了设备的参数化设计。参数化设计可以随着用户给定的设计参数而更改模型,提高了设计效率。基于此背景,本文以UG为开发平台,利用VC++6.0面向对象的编程技术,在UG/Open API开发平台上,创建了采煤机、液压支架、刮板输送机零部件外形特征的参数化模型,利用MenuScript建立了菜单,UIStyler建立用户定义对话框,完成了综采工作面设备配套尺寸的参数化设计系统,并将其无缝嵌套到UG软件中。该系统实现参数化尺寸驱动,设计人员修改设计参数就可以得到更新综采主要设备的模型,从而更新其装配体的三维模型,并节约了综采设备配套的时间。该系统界面简洁直观,操作方便,人机交互性能良好。最后利用UG运动仿真功能对“三机”三维模型进行运动分析,形象地展现了综采工作面配套设备的运动过程,实现了运动中各个零件之间的测量和干涉检验,验证了配套的合理性和可行性等。更多还原

【Abstract】 It is the "three machines" geometry size matching design in the mining face that ensures matching size between shearer, hydraulic powered support and scraper conveyor. Only when these three kinds of equipment completely agree with each other, does it make sure no interference when equipments work, and can maximize the efficiency of the machinery. At present, the equipments of fully mechanized mining face match mostly use two-dimension matching chart, it would neither reflect visually and intuitively the mechanized mining face matching situation nor modify dynamically and solve fit-up inspection, interference detection as well as motion simulation in matching situation. For this reason, we create 3D model. The mechanized mining face equipments assembly 3D model not only reflect directly and comprehensives the matching relations between them, but also establish the follow-up finite-element analysis using 3D model, it provides a more effective method for the research of the mining face equipments. With the development of the computer, designers have developed new method of parametric design based on the 3D model. Designer can avoid repetitive model by using the parameterization design, who can utilize updated model to research 3D assemblage, interface check, limited meta-analysis, and dynamic simulation. As a result, it improves the quality of the design and shortens the period of the design. The equipment of this paper researched looks and structures are almost the same and will not change dramatically. It is necessary to do further development based on UG software in order to avoid repeating creation of model, accomplish parametric design of equipment characteristics. Parameterization model can be changed according to design parameters which were given by user, in this way, the work efficiency promotes greatly.Based on the background, the parameterization model of shearer, hydraulic powered support and scraper conveyor are built on the platform UG by using the VC++6.0 object-oriented programming technique, create various parts menu using Menu Script and dialog box using UG/Open UIStyler. Ultimately, create parametric design system of matching size of mechanized working face equipments. Designer get renewal equipment’s 3D model when modify directly the design parameters, and then the mechanized mining face equipments assembly 3D model will be update, meanwhile, the system reduces equipments in fully mechanized mining face matching time. The system has the features: simple interface, easy to use, favorable man-machine conversation and so on.At last, motion simulation for 3Dmodel of "three machines" by UG/MOTION, it visually shows the motion process of mechanized working face equipments, realizes component interference checking and measurement in the process of movement, and tests the rationality and feasibility of matching.更多还原
