【摘要】：隨著我國石材行業(yè)的快速發(fā)展,迫切需要革新開采工藝技術(shù)和開采裝備水平。作為花崗石鋸解領(lǐng)域的最先進(jìn)成果,多繩金剛石串珠鋸(多繩鋸)是世界上前沿的石材加工設(shè)備,具有靈活、安全、高效、環(huán)保、成荒率高等優(yōu)點(diǎn)。國內(nèi)多繩鋸的發(fā)展還處在起步階段,因此對多繩鋸相關(guān)部件的研究有重要的意義。本文旨在研究擁有自主知識產(chǎn)權(quán)的多繩金剛石串珠鋸荒料車系統(tǒng)和整機(jī)制動系統(tǒng)。 通過應(yīng)用機(jī)械產(chǎn)品現(xiàn)代設(shè)計方法,擬定了多繩金剛石串珠鋸荒料車的方案創(chuàng)新設(shè)計流程。深入分析了國外多繩金剛石串珠鋸荒料車的結(jié)構(gòu)特點(diǎn),確定了荒料車的技術(shù)參數(shù)及性能要求,并給出了荒料車的總體設(shè)計要求。對多繩金剛石串珠鋸荒料車進(jìn)行了功能分解,建立了功能-結(jié)構(gòu)關(guān)系圖,對結(jié)構(gòu)進(jìn)行了模塊劃分,然后將TRIZ應(yīng)用到方案設(shè)計過程中,完成了荒料車的創(chuàng)新設(shè)計,并對各模塊應(yīng)用Solidworks軟件進(jìn)行建模、裝配,最后完成荒料車的三維設(shè)計。 基于ANSYS Workbench(AWE)協(xié)同開發(fā)平臺,就如何將三維軟件建立的荒料車模型直接導(dǎo)入平臺進(jìn)行了探究,實(shí)現(xiàn)Solidworks三維設(shè)計、CAE分析的協(xié)同和管理。介紹了有限元分析前期的材料、網(wǎng)格劃分、邊界條件的施加、載荷等處理方法,對多繩金剛石串珠鋸荒料車進(jìn)行有限元分析,同時應(yīng)用優(yōu)化設(shè)計思想,利用基于實(shí)驗技術(shù)的DOE模塊對荒料車進(jìn)行輕量化設(shè)計,最后得到綜合指標(biāo)趨于最好的多繩金剛石串珠鋸荒料車設(shè)備。 利用ANSYS Workbench中的模態(tài)分析模塊分析了多繩金剛石串珠鋸荒料車的固有頻率、振型,提取了前六階模態(tài),找出了變形的最大區(qū)域。擬定了動態(tài)性能的優(yōu)劣性評價方法,然后依據(jù)評價方法對多繩金剛石串珠鋸荒料車車架的模態(tài)分析結(jié)果進(jìn)行了評估,從而進(jìn)一步驗證了荒料車的設(shè)計合理性。 通過多繩金剛石串珠鋸各個輪系的深入研究分析,確定了選用能耗制動為主動輪的制動方式,經(jīng)過計算可知制動功率、制動電阻以及制動單元的電流都與制動時間t有關(guān)。張緊輪、定位輪通過串珠繩與張緊輪繩槽的摩擦力來制動,以帶傳動的分析方法來分析串珠繩與張緊輪繩槽之間的傳動情況,計算出了最大靜摩擦力所能提供的最大制動轉(zhuǎn)矩及最短制動時間。最后對整機(jī)制動單元進(jìn)行了計算和分析。 本課題得到了山東省科技發(fā)展計劃項目(2010GGX10405)和山東省自然科學(xué)基金(ZR2012EEM032)資助。
[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. The project is supported by Shandong Science and Technology Development Program (2010 GGX10405) and Shandong Natural Science Foundation (ZR2012 EEM032).
