【摘要】：隨著社會(huì)經(jīng)濟(jì)的飛速發(fā)展,各行各業(yè)對(duì)能源的需求量不斷增加,這種趨勢(shì)推動(dòng)了采礦業(yè)的發(fā)展。在采礦業(yè)不斷的發(fā)展下,各種礦洞應(yīng)運(yùn)而生,巷道清理機(jī)的需求量也相應(yīng)增加。巷道清理機(jī)的工作裝置是其工作的主要部件,對(duì)工作裝置進(jìn)行研究是很有必要的。本文在了解巷道清理機(jī)國(guó)內(nèi)外發(fā)展現(xiàn)狀的基礎(chǔ)上,參考國(guó)內(nèi)外的同類型機(jī)型,對(duì)工作裝置的結(jié)構(gòu)進(jìn)行分析。在對(duì)工作阻力的分析和對(duì)工作裝置危險(xiǎn)工況的確定的基礎(chǔ)上,分析工作裝置各個(gè)工況的受力情況,對(duì)工作裝置的動(dòng)力學(xué)分析提供理論依據(jù)。利用Slidworks軟件建立巷道清理機(jī)工作裝置的模型。將模型導(dǎo)入ADAMS中,建立巷道清理機(jī)工作裝置的虛擬樣機(jī)模型。在ADAMS中對(duì)工作裝置進(jìn)行運(yùn)動(dòng)學(xué)仿真,分析其工作范圍;對(duì)工作裝置各個(gè)工況進(jìn)行動(dòng)力學(xué)仿真,分析各個(gè)工況下油缸和鉸點(diǎn)的受力情況。通過運(yùn)動(dòng)學(xué)分析結(jié)果確定工作裝置的工作范圍,通過動(dòng)力學(xué)分析結(jié)果校核油缸的選型是否合理,同時(shí)分析大臂、斗桿、滑移臂和破碎錘的危險(xiǎn)工況。利用ANSYS軟件靜力學(xué)分析模塊,針對(duì)動(dòng)力學(xué)分析出的危險(xiǎn)工況進(jìn)行有限元分析,分析工作裝置的大臂、斗桿、滑移臂和破碎錘在危險(xiǎn)工況下的應(yīng)力應(yīng)變情況。對(duì)破碎錘進(jìn)行模態(tài)分析,分析出其自由模態(tài)下的固有頻率和各階頻率的振型,對(duì)破碎錘工作頻率的選擇和破碎錘結(jié)構(gòu)的設(shè)計(jì)具有一定的參考作用。
[Abstract]:With the rapid development of social economy, the demand for energy in various industries is increasing, which promotes the development of mining industry. With the development of mining industry, all kinds of mine holes emerge as the times require, and the demand of roadway cleaning machine increases accordingly. The working device of roadway cleaning machine is the main part of its work, so it is necessary to study the working device. On the basis of understanding the present situation of roadway cleaning machine at home and abroad and referring to the same type of machine at home and abroad, the structure of the working device is analyzed in this paper. Based on the analysis of the working resistance and the determination of the dangerous working condition of the working device, the stress of each working condition is analyzed, which provides the theoretical basis for the dynamic analysis of the working device. The model of working device of roadway cleaning machine is established by using Slidworks software. The model is imported into ADAMS, and the virtual prototype model of the working device of roadway cleaning machine is established. The kinematics simulation of the working device is carried out in ADAMS, and the working range is analyzed, and the dynamic simulation of each working condition is carried out to analyze the stress of the cylinder and hinge under each working condition. The working range of the working device is determined by the kinematics analysis results and the results of dynamics analysis are used to check whether the selection of the oil cylinder is reasonable or not and the dangerous working conditions of the big arm the bucket rod the slip arm and the broken hammer are analyzed at the same time. Using ANSYS software statics analysis module, the finite element analysis is carried out to analyze the stress and strain of the working device's big arm, bucket rod, slip arm and broken hammer under the dangerous working condition. The modal analysis of the hammer is carried out, and the natural frequency and the modes of each order frequency in the free mode are analyzed, which can be used as a reference for the selection of the working frequency of the hammer and the design of the structure of the hammer.
