【摘要】：脫掛抱索器客運(yùn)索道相較于傳統(tǒng)固定抱索器索道具有站外速度快站內(nèi)速度低，單個(gè)吊廂質(zhì)量較大等特點(diǎn)，因此針對固定抱索器索道的線路布置方案并不適用于脫掛抱索器客運(yùn)索道系統(tǒng)。因此我們必須設(shè)計(jì)出合理的方案來對脫掛抱索器客運(yùn)索道系統(tǒng)進(jìn)行線路優(yōu)化布置。 本論文以北京起重運(yùn)輸機(jī)械設(shè)計(jì)研究院設(shè)計(jì)開發(fā)的山西渾源縣恒山索道為研究對象，針對站外線路布置問題，運(yùn)用離散法建立了多集中載荷懸索系統(tǒng)的振動(dòng)模型，求解了吊廂處于單跨不同位置時(shí)的一階固有振動(dòng)頻率，找出了不同因素對其一階頻率的影響；針對站內(nèi)加減速線路布置問題，，建立了吊廂加減速運(yùn)動(dòng)的動(dòng)力學(xué)模型，并對加減速過程的擺動(dòng)情況進(jìn)行仿真分析，優(yōu)化設(shè)計(jì)出了5m/s及6m/s工況下的進(jìn)出站加減速裝置布置方案。論文主要研究工作有： ①采用離散法建立了單集中載荷及多集中載荷作用下懸索系統(tǒng)振動(dòng)的動(dòng)力學(xué)模型，得出了單集中載荷及多集中載荷兩種情況下懸索系統(tǒng)一階固有振動(dòng)頻率的變化曲線，并研究了索道張力、索道跨距、吊廂質(zhì)量等因素對多集中載荷作用下懸索系統(tǒng)一階固有振動(dòng)頻率的影響； ②建立索道跨距合理布置的優(yōu)化設(shè)計(jì)方法，計(jì)算出了不同跨距下多集中載荷懸索系統(tǒng)一階固有振動(dòng)頻率的最大值及最小值，并與多集中載荷懸索系統(tǒng)內(nèi)部激勵(lì)頻率的最大值及最小值進(jìn)行對比，找出跨距的合理布置范圍； ③建立纜車進(jìn)出站過程的動(dòng)力學(xué)模型，設(shè)計(jì)出5m/s及6m/s工況下纜車進(jìn)出站的速度曲線，并與勻加減速情況下的擺角大小進(jìn)行對比分析，得出在S形加減速曲線下的吊廂擺角明顯小于勻加減速下的擺角，并以此優(yōu)化布置了脫掛索道站內(nèi)加減速皮帶輪的速度排布方案。
[Abstract]:Compared with the traditional fixed cable-hold cableway, the passenger ropeway with cable-holding device has the characteristics of low speed outside the station, high quality of single suspension box, and so on. Therefore, the route layout scheme for fixed cable-hold cableway is not suitable for the passenger ropeway system with cable holder. Therefore, we must design a reasonable scheme to optimize the layout of passenger ropeway system with cable holder. . This paper takes Hengshan cableway in Hunyuan County, Shanxi Province, which is designed and developed by Beijing lifting and Transportation Machinery Design Research Institute, as the research object, aiming at the layout of lines outside the station. The vibration model of multi-concentrated load suspension system is established by using the discrete method. The first order natural vibration frequency of the suspension box at different positions of single span is solved, and the influence of different factors on the first order frequency is found out. Aiming at the layout of acceleration and deceleration line in the station, the dynamic model of the acceleration and deceleration motion of the suspension box is established, and the swing of the acceleration and deceleration process is simulated and analyzed. The layout scheme of acceleration and deceleration device in and out of the station under the operating conditions of 5m / s and 6m / s is optimized and designed. The main research work of this paper is as follows: 1. The dynamic model of suspension system vibration under single concentrated load and multiple concentrated load is established by discrete method. The change curves of the first order natural vibration frequency of the suspension system under the condition of single concentrated load and multiple concentrated load are obtained, and the tension of the cableway and the span of the cableway are studied. The influence of the mass of the suspension box on the first order natural vibration frequency of the suspension system under the action of multiple concentrated loads; (2) the optimum design method for the rational arrangement of the span of the cableway is established, and the maximum and minimum values of the first order natural vibration frequency of the cable-suspension system with multiple concentrated loads under different spans are calculated. Compared with the maximum and minimum of the internal excitation frequency of the multi-concentrated load suspension system, the reasonable layout range of the span is found out. (3) establish the dynamic model of the process of the cable car entering and leaving station, design the speed curve of the cable car in the condition of 5m / s and 6m / s, and compare it with the swing angle of the cable car under the condition of uniform acceleration and deceleration. It is concluded that the swing angle of the suspension box under the S-shape acceleration and deceleration curve is obviously smaller than that under the uniform acceleration and deceleration, and the speed distribution scheme of the acceleration and deceleration belt pulley in the ropeway station is optimized.
