【摘要】：礦井提升機是礦井運輸中的咽喉設(shè)備,是井下與地面聯(lián)系的重要工具,其安全可靠性直接關(guān)系到生產(chǎn)的正常進行和人員安全。目前纏繞式礦井提升機在計算機輔助設(shè)計方面,其生產(chǎn)廠家及研究機構(gòu)主要集中在對單個零部件的有限元分析、結(jié)構(gòu)參數(shù)優(yōu)化等方面,對提升機主軸裝置整體進行數(shù)值模擬計算及結(jié)構(gòu)動力學研究分析方面還比較欠缺。本文主要針對大型礦井提升機主軸裝置展開研究,首先通過對大型礦井提升機主軸在多個典型工況下的仿真分析研究,得到各個工況下的等效應力及其變形,并在最大等效應力條件下進行疲勞壽命研究,發(fā)現(xiàn)最先零件疲勞失效的部位并預測其使用壽命;其次對大型礦井提升機主軸與支輪的熱裝過程進行了熱固耦合仿真研究,得到不同過盈量條件下的溫度場及應力場分布特性,研究方法及結(jié)果可為過盈配合的熱裝工藝提供理論支撐與生產(chǎn)指導;同時對大型礦井提升機主軸裝置結(jié)構(gòu)動力學進行仿真分析,求解出各階模態(tài)下的極限轉(zhuǎn)速,為提高其運行效率提供理論依據(jù);最后對大型礦井提升機主軸裝置制動過程進行了仿真分析研究,求解出在整個制動過程溫度場的分布、熱應力分布,為制動系統(tǒng)設(shè)計及選擇制動盤、閘瓦材料時提供參考。本論文的研究方法與成果,可廣泛地應用于不同型號的礦井提升設(shè)備,有助于提高產(chǎn)品設(shè)計的可靠性,提升產(chǎn)品質(zhì)量,縮短產(chǎn)品的設(shè)計開發(fā)周期,具有一定的經(jīng)濟效益。
[Abstract]:Mine hoist is the throat equipment in mine transportation and an important tool for the connection between underground and ground. Its safety and reliability are directly related to the normal operation of production and personnel safety. At present, in the area of computer aided design of winding mine hoists, its manufacturers and research institutions mainly focus on the finite element analysis of individual parts and the optimization of structural parameters, etc. The numerical simulation and structural dynamics analysis of the main shaft unit of hoist are still lacking. The main purpose of this paper is to study the main shaft device of large mine hoist. Firstly, the equivalent stress and deformation of the shaft of large mine hoist under several typical working conditions are obtained through the simulation and analysis of the main shaft of the large mine hoist. Under the condition of maximum equivalent stress, the fatigue life of the first part is found out and its service life is predicted. Secondly, the thermal-solid coupling simulation of the hot loading process between the main shaft and the supporting wheel of a large mine hoist is carried out. The distribution characteristics of temperature field and stress field under different interference quantities are obtained. The research methods and results can provide theoretical support and production guidance for the hot charging process of interference fit. At the same time, the structural dynamics of the main shaft unit of the large mine hoist is simulated and analyzed, and the limit rotational speed under each order mode is solved, which provides a theoretical basis for improving the running efficiency. Finally, the braking process of the main shaft of large mine hoist is simulated and studied, and the distribution of temperature field and thermal stress in the whole braking process is solved, which provides a reference for the design of braking system and the selection of brake disc and brake shoe material. The research methods and results of this paper can be widely used in different types of mine hoisting equipment, which can help to improve the reliability of product design, improve product quality, shorten the design and development cycle of products, and have certain economic benefits.
