【摘要】：近几年来，随着城镇化建设步伐加快，高层建筑越来越多，高层建筑外墙清洁、安装、维护等问题日益凸显，这就为擦窗机提供了较大的发展空间。由于擦窗机属非标产品，设计计算繁复、工作量大，目前传统的设计方法效率低、精度差，很难满足现代高性能擦窗机设计要求。为此，本文开发了擦窗机伸缩臂计算机辅助设计与优化系统。提出了擦窗机作业范围一定的前提下，，确定伸缩臂节数及长度尺寸的方法，该方法综合考虑了材料利用率、制造成本、伸缩臂重量等因素，使伸缩臂设计方案更合理。依据相关擦窗机设计规范，对不同工况伸缩臂受力进行了分析，计算出危险截面应力。在满足强度和作业尺寸要求的前提下，以伸缩臂重量轻、材料利用充分为目标，建立多目标擦窗机伸缩臂截面尺寸优化设计模型，并针对具体实例，给出优化设计结果。采用去材料的方法对优化后伸缩臂进行后处理，从而实现利用标准型材的同时减轻了伸缩臂重量。充分利用Visual Basic和Matlab编程语言各自的优势，运用混合编程技术，开发出擦窗机伸缩臂计算机辅助设计计算与优化软件，实现了伸缩臂长度尺寸的确定、截面尺寸的优化、方案图纸的自动绘制等功能。擦窗机伸缩臂设计计算方法的研究及相应的计算机辅助设计软件的开发，有效地提高了擦窗机设计效率和质量，减轻了设计工作量。
[Abstract]:In recent years, with the acceleration of the pace of urbanization, more and more high-rise buildings, high-rise building exterior wall cleaning, installation, maintenance and other issues are increasingly prominent, which provides a large development space for window cleaning machines. Because the window cleaning machine is a non-standard product, the design calculation is complicated, the workload is heavy, and the traditional design method is low efficiency and poor precision, so it is difficult to meet the design requirements of modern high performance window cleaning machine. Therefore, a computer aided design and optimization system for the telescopic arm of window cleaning machine is developed in this paper. A method for determining the number and length of telescopic arm joints is proposed on the premise of certain working range of window polishing machine. The design scheme of telescopic arm is more reasonable by taking into account the factors of material utilization, manufacturing cost, weight of telescopic arm and so on. According to the design code of relevant window cleaning machine, the stress of telescopic arm under different working conditions is analyzed, and the dangerous section stress is calculated. On the premise of meeting the requirements of strength and operation size, the optimum design model of the section size of telescopic arm of multi-objective window cleaning machine is established with the aim of light weight of telescopic arm and full utilization of materials, and the optimization design result is given in the light of concrete examples. The post-treatment of the optimized retractive arm is carried out by the method of material removal, so that the weight of the telescopic arm can be reduced by using the standard profile at the same time. Making full use of the advantages of Visual basic and Matlab programming language, the computer aided design and optimization software for the telescopic arm of window polishing machine is developed by using the mixed programming technology, which realizes the determination of the length dimension of the telescopic arm and the optimization of the section size. Automatic drawing of project drawings and other functions. The research on the design and calculation method of the telescopic arm of the window cleaning machine and the development of the corresponding computer aided design software have effectively improved the design efficiency and quality of the window cleaning machine and reduced the design workload.
