【摘要】：随着我国石材行业的快速发展,迫切需要革新开采工艺技术和开采装备水平。作为花岗石锯解领域的最先进成果,多绳金刚石串珠锯(多绳锯)是世界上前沿的石材加工设备,具有灵活、安全、高效、环保、成荒率高等优点。国内多绳锯的发展还处在起步阶段,因此对多绳锯相关部件的研究有重要的意义。本文旨在研究拥有自主知识产权的多绳金刚石串珠锯荒料车系统和整机制动系统。通过应用机械产品现代设计方法,拟定了多绳金刚石串珠锯荒料车的方案创新设计流程。深入分析了国外多绳金刚石串珠锯荒料车的结构特点,确定了荒料车的技术参数及性能要求,并给出了荒料车的总体设计要求。对多绳金刚石串珠锯荒料车进行了功能分解,建立了功能-结构关系图,对结构进行了模块划分,然后将TRIZ应用到方案设计过程中,完成了荒料车的创新设计,并对各模块应用Solidworks软件进行建模、装配,最后完成荒料车的三维设计。基于ANSYS Workbench(AWE)协同开发平台,就如何将三维软件建立的荒料车模型直接导入平台进行了探究,实现Solidworks三维设计、CAE分析的协同和管理。介绍了有限元分析前期的材料、网格划分、边界条件的施加、载荷等处理方法,对多绳金刚石串珠锯荒料车进行有限元分析,同时应用优化设计思想,利用基于实验技术的DOE模块对荒料车进行轻量化设计,最后得到综合指标趋于最好的多绳金刚石串珠锯荒料车设备。利用ANSYS Workbench中的模态分析模块分析了多绳金刚石串珠锯荒料车的固有频率、振型,提取了前六阶模态,找出了变形的最大区域。拟定了动态性能的优劣性评价方法,然后依据评价方法对多绳金刚石串珠锯荒料车车架的模态分析结果进行了评估,从而进一步验证了荒料车的设计合理性。通过多绳金刚石串珠锯各个轮系的深入研究分析,确定了选用能耗制动为主动轮的制动方式,经过计算可知制动功率、制动电阻以及制动单元的电流都与制动时间t有关。张紧轮、定位轮通过串珠绳与张紧轮绳槽的摩擦力来制动,以带传动的分析方法来分析串珠绳与张紧轮绳槽之间的传动情况,计算出了最大静摩擦力所能提供的最大制动转矩及最短制动时间。最后对整机制动单元进行了计算和分析。本课题得到了山东省科技发展计划项目(2010GGX10405)和山东省自然科学基金(ZR2012EEM032)资助。
[Abstract]:With the rapid development of stone industry in China, it is urgent to innovate mining technology and mining equipment level. As the most advanced achievement in the field of granite sawing, multi-rope diamond beaded saw (multi-rope saw) is the world's leading stone processing equipment, with the advantages of flexibility, safety, efficiency, environmental protection, high wasteland rate and so on. The development of multi-rope saws in China is still in its infancy, so it is of great significance to study the related parts of multi-rope saws. The purpose of this paper is to study the multi-rope diamond bead saw truck system and the whole machine braking system with independent intellectual property rights. By applying the modern design method of mechanical products, the innovative design flow of multi-rope diamond bead sawing machine was worked out. The structural characteristics of foreign multi-rope diamond bead saw trucks are deeply analyzed, the technical parameters and performance requirements of the barren trucks are determined, and the overall design requirements of the barren trucks are given. The functional decomposition of the multi-rope diamond bead saw truck was carried out, the function-structure relation diagram was established, the structure was divided into modules, and Triz was applied to the design process of the scheme, and the innovative design of the barren car was completed. The modules are modeled and assembled by Solidworks software. Finally, the 3D design of the barren car is completed. Based on the ANSYS Workbench (awe) collaborative development platform, this paper probes into how to directly import the 3D software model into the platform, and realizes the collaborative and management of CAE analysis in Solidworks 3D design. The material, mesh division, application of boundary conditions, load and other treatment methods in the early stage of finite element analysis are introduced. The finite element analysis of multi-rope diamond bead saw truck is carried out, and the idea of optimization design is applied at the same time. Using the DOE module based on the experiment technology, the light weight design of the barren truck is carried out, and finally, the equipment of the multi-rope diamond bead saw truck with the best synthetic index is obtained. The modal analysis module of ANSYS Workbench is used to analyze the natural frequency and vibration pattern of the multi-rope diamond bead sawing truck. The first six modes are extracted and the maximum deformation region is found out. The evaluation method of dynamic performance is proposed, and then the modal analysis results of multi-rope diamond bead saw frame are evaluated according to the evaluation method, which further verifies the rationality of the design of the barren truck. Through the deep research and analysis of each gear train of multi-rope diamond beaded saw, the braking mode of energy consumption brake as active wheel is determined. The braking power, braking resistance and current of braking unit are all related to braking time t by calculation. To brake by the friction between the bead rope and the tensioning wheel grooves, and to analyze the transmission between the beaded rope and the tensioner rope slot by means of an analytical method of belt transmission. The maximum braking torque and the shortest braking time provided by the maximum static friction force are calculated. Finally, the braking unit of the whole machine is calculated and analyzed.
