【摘要】：高彈性聯(lián)軸器是一種常見的軸系連接部件，具有較好的阻尼性能、位移補(bǔ)償性能等等，在船舶制造等領(lǐng)域得到了廣泛應(yīng)用。而高彈性聯(lián)軸器中的橡膠彈性元件作為高彈的重要元件，其性能對(duì)于整個(gè)聯(lián)軸器的運(yùn)行有很大的影響。 目前國(guó)內(nèi)外對(duì)于橡膠彈性元件的發(fā)展更多地集中在了其傳扭能力和轉(zhuǎn)速限制上而對(duì)于其熱學(xué)性能則依舊有較大的研究空間。基于此本文主要探討了在給定工況下高彈性聯(lián)軸器橡膠彈性元件的傳熱與溫度場(chǎng)分布。 通過等強(qiáng)度理論，本文提出了一種對(duì)與橡膠元件在工作中生熱方式的簡(jiǎn)化模型，同時(shí)通過對(duì)于現(xiàn)有的傳熱學(xué)理論的學(xué)習(xí)，編寫了包括熱傳導(dǎo)、對(duì)流散熱、熱輻射在內(nèi)的較完整的數(shù)學(xué)模型以及建立了相應(yīng)的有限元模型，并通過有限元仿真與臺(tái)架試驗(yàn)，驗(yàn)證了該生熱簡(jiǎn)化模型與傳熱數(shù)學(xué)模型能夠?qū)ο鹉z元件的生熱與傳熱狀態(tài)進(jìn)行比較好的模擬。 本文利用711所的大型臺(tái)架試驗(yàn)設(shè)備，設(shè)計(jì)實(shí)施了對(duì)目標(biāo)聯(lián)軸器橡膠彈性元件的試驗(yàn)，在給定工況下，，通過紅外與熱電偶，對(duì)LS2110型高彈性聯(lián)軸器的橡膠元件進(jìn)行了表面與內(nèi)部溫度測(cè)量，得到了一套較好的溫度分布數(shù)據(jù)，并將該工況下有限元仿真模型所得到的溫度分布云圖與試驗(yàn)所得的測(cè)量數(shù)據(jù)進(jìn)行了比較，其誤差在10%以內(nèi)，證明仿真獲得了較好的結(jié)果。 在仿真模型的可靠性獲得驗(yàn)證后，本文利用該模型對(duì)現(xiàn)有的橡膠件進(jìn)行了一些結(jié)構(gòu)優(yōu)化，并總結(jié)了具有規(guī)律性的結(jié)構(gòu)優(yōu)化方法。
[Abstract]:High elastic coupling is a kind of common shafting connecting parts with good damping performance, displacement compensation performance and so on. It has been widely used in shipbuilding and other fields. As an important element of high elasticity, the performance of rubber elastic element in high elastic coupling has great influence on the operation of the whole coupling. At present, the development of rubber elastic elements is more focused on the torsion transfer ability and speed limit, but there is still more research space for the thermal properties of rubber elastic elements. Based on this, the heat transfer and temperature field distribution of rubber elastic elements of high elastic coupling under given working conditions are discussed. Based on the theory of equal strength, this paper presents a simplified model of heat generation in the work with rubber elements. Through the study of the existing heat transfer theory, the author has compiled the models including heat conduction, convection and heat dissipation. The complete mathematical model including thermal radiation and the corresponding finite element model are established, and the finite element simulation and bench test are carried out. It is verified that the simplified heat generation model and the mathematical model of heat transfer can be used to simulate the heat generation and heat transfer of rubber elements. In this paper, the rubber elastic element of the target coupling is designed and implemented by using the large scale bench test equipment of 711 institute. Under the given working condition, infrared and thermocouple are adopted. The surface and internal temperature of rubber elements of LS2110 type high elastic coupling were measured and a set of better temperature distribution data was obtained. The temperature distribution cloud diagram obtained by the finite element simulation model under this working condition is compared with the measured data, and the error is less than 10%, which proves that the simulation has good results. After the reliability of the simulation model is verified, this paper uses the model to optimize the structure of the existing rubber parts, and summarizes the regular structural optimization methods.
