【摘要】：伴隨著采煤業(yè)的快速發(fā)展,礦用無(wú)軌膠輪車得到了廣泛的應(yīng)用,但由于其干式制動(dòng)器失效事故頻發(fā),《礦用防爆柴油機(jī)無(wú)軌膠輪車通用技術(shù)條件標(biāo)準(zhǔn)MT T 959-2006》要求載重量2t(含2t)以上的無(wú)軌膠輪車應(yīng)采用濕式制動(dòng)方式。目前國(guó)內(nèi)濕式制動(dòng)器研究時(shí)間較短,所使用的濕式制動(dòng)器主要是普通型濕式多盤(pán)制動(dòng)器和失壓型濕式多盤(pán)制動(dòng)器。多功能濕式多盤(pán)制動(dòng)器由于結(jié)構(gòu)相對(duì)復(fù)雜,市場(chǎng)應(yīng)用不多,但較其他濕式制動(dòng)器具有安全、可靠的制動(dòng)性能,因此具有廣闊的使用前景。主要研究工作如下:(1)計(jì)算制動(dòng)器要求的制動(dòng)力矩,對(duì)多功能濕式多盤(pán)制動(dòng)器進(jìn)行結(jié)構(gòu)優(yōu)化設(shè)計(jì)以避免靜摩擦片卡死現(xiàn)象,使后期維護(hù)更加方便,驗(yàn)算所設(shè)計(jì)制動(dòng)器的制動(dòng)性能,運(yùn)用Solidworks對(duì)關(guān)鍵元件進(jìn)行應(yīng)力應(yīng)變有限元分析。(2)對(duì)多功能濕式多盤(pán)制動(dòng)器的配套液壓制動(dòng)控制系統(tǒng)進(jìn)行總體方案設(shè)計(jì),根據(jù)所設(shè)計(jì)制動(dòng)器的參數(shù)對(duì)雙路制動(dòng)閥、雙路充液閥、手柄閥、蓄能器等關(guān)鍵液壓元件進(jìn)行選型設(shè)計(jì),以滿足制動(dòng)性能和制動(dòng)次數(shù)要求。(3)對(duì)雙路制動(dòng)閥、雙路充液閥和多功能濕式多盤(pán)制動(dòng)器的結(jié)構(gòu)和數(shù)學(xué)模型進(jìn)行分析,利用AMESim中HCD設(shè)計(jì)庫(kù)對(duì)其進(jìn)行建模,然后利用HYD庫(kù)對(duì)整個(gè)液壓制動(dòng)控制系統(tǒng)進(jìn)行建模,最后對(duì)不同狀態(tài)下仿真模型進(jìn)行分析,驗(yàn)證該系統(tǒng)性能的可靠性。(4)設(shè)計(jì)實(shí)驗(yàn)系統(tǒng)總體方案,搭建制動(dòng)控制系統(tǒng)實(shí)驗(yàn)平臺(tái),進(jìn)行實(shí)驗(yàn)驗(yàn)證,實(shí)驗(yàn)與仿真結(jié)果對(duì)比分析表明所設(shè)計(jì)多功能濕式多盤(pán)制動(dòng)器和液壓制動(dòng)控制系統(tǒng)滿足要求。
[Abstract]:With the rapid development of coal mining industry, mining trackless rubber wheel car has been widely used. However, due to the frequent failure accidents of dry brake, the general technical condition of mine explosion-proof diesel trackless rubber wheel vehicle (MTT959-2006) requires that the trackless rubber wheel vehicle with a load of more than 2t (including 2t) should adopt wet braking mode. At present, the domestic wet braking mode is required for the trackless rubber wheel vehicle with heavy load of more than 2t (including 2t). The research time of type brake is short, The wet brakes used are mainly common wet multi-disc brakes and depressurized wet multi-disc brakes. Due to the relative complexity of the structure, the multi-function wet multi-disc brakes are not widely used in the market, but they are safer than other wet brakes. Because of its reliable braking performance, it has broad application prospects. The main research work is as follows: 1) calculating brake torque required by brake and optimizing the structure of multi-function wet multi-disc brake to avoid static friction plate sticking. Making the later maintenance more convenient, checking the braking performance of the brake designed by the Institute, using Solidworks to carry out the stress and strain finite element analysis of the key components. (2) the overall scheme design of the supporting hydraulic brake control system of the multi-function wet multi-disc brake is carried out. According to the parameters of the designed brake, the key hydraulic components, such as double-channel brake valve, double-channel filling valve, handle valve, accumulator and so on, are selected and designed to meet the braking performance and braking times. The structure and mathematical model of two-way liquid filling valve and multi-function wet multi-disc brake are analyzed. The model is modeled by HCD design library in AMESim, and then the whole hydraulic brake control system is modeled by HYD library. Finally, the simulation models in different states are analyzed to verify the reliability of the system. The overall scheme of the experimental system is designed, and the experimental platform of the braking control system is built, and the experimental verification is carried out. The experimental and simulation results show that the multi-function wet multi-disc brake and hydraulic brake control system meet the requirements.
