【摘要】：軸向移動繩系統(tǒng)在生產(chǎn)生活中有著廣泛的應(yīng)用,比如磁帶、貨物輸送帶、帶鋸、繩系衛(wèi)星、纜車等都可以看成是軸向移動的繩系統(tǒng)。而軸向移動繩系統(tǒng)的橫向振動是制約其應(yīng)用的一個關(guān)鍵因素。因此,降低軸向移動繩系統(tǒng)的橫向振動對設(shè)備的設(shè)計很重要。本文的研究內(nèi)容來源于國家自然科學(xué)基金項目“時變自由度軸向繩移系統(tǒng)的參數(shù)振動及實(shí)驗(yàn)研究”(項目編號：51305115)。文中對定長度和變長度的軸向移動繩系統(tǒng)的橫向振動分別進(jìn)行分析,提出了衰減其橫向振動能量的方法。本文以軸向移動繩系統(tǒng)為研究對象,首先對軸向移動繩系統(tǒng)應(yīng)用分析力學(xué)法進(jìn)行建模,采用哈密頓原理來建立系統(tǒng)的動力學(xué)方程。然后,對于長度不隨時間改變的軸向移動繩系統(tǒng),計算了其橫向振動能量,并將總能量表達(dá)式對時間進(jìn)行求導(dǎo),分析得出總能量隨時間恒定衰減的條件,并依照條件給出所應(yīng)施加控制力的形式與作用位置。對于長度隨時間變化的軸向移動繩系統(tǒng),采用變量代換的方法,使位移變量不再受時間變量的限制,并提出一種滿足邊界條件的橫向位移表達(dá)式,在此基礎(chǔ)上展開分析橫向振動能量的振動特性。最后,依照分析的實(shí)驗(yàn)要求設(shè)計并搭建實(shí)驗(yàn)平臺,并實(shí)驗(yàn)驗(yàn)證分析的正確性。該研究為工程上軸向移動設(shè)備的設(shè)計提供了理論基礎(chǔ)。
[Abstract]:Axial mobile rope system has been widely used in production and life, such as tape, cargo conveyor belt, band saw, rope system satellite, cable car and so on can be regarded as axial moving rope system. The lateral vibration of the axial moving rope system is a key factor restricting its application. Therefore, reducing the lateral vibration of the axial moving rope system is very important to the design of the equipment. The research content of this paper comes from the project of National Natural Science Foundation of China, "Parameter Vibration and Experimental study of Time-Varying Freedom of Freedom Axial Rope shifting system" (item No.: 51305115). In this paper, the transverse vibration of a fixed length and variable length axial moving rope system is analyzed, and a method to attenuate its transverse vibration energy is proposed. In this paper, the axial moving rope system is taken as the research object. Firstly, the analytical mechanics method is used to model the axial moving rope system, and the Hamiltonian principle is used to establish the dynamic equation of the system. Then, for the axial moving rope system whose length does not change with time, the transverse vibration energy is calculated, and the time is derived from the expression of the total energy, and the condition of constant attenuation of the total energy with time is obtained. According to the conditions, the form and position of the control force should be given. For the axial moving rope system whose length varies with time, the displacement variable is no longer limited by the time variable by the method of variable substitution, and a lateral displacement expression satisfying the boundary condition is proposed. On this basis, the vibration characteristics of transverse vibration energy are analyzed. Finally, the experimental platform is designed and built according to the experimental requirements of the analysis, and the correctness of the analysis is verified. The research provides a theoretical basis for the design of engineering axial mobile equipment.
