【摘要】：摘要：隨著現(xiàn)代社會對高生產(chǎn)率的不斷追求,機械設備的運轉速度不斷提高,隨之帶來的慣性作用明顯增加,由此產(chǎn)生的振動、噪聲等問題嚴重影響機器的工作性能和使用壽命。為了適應現(xiàn)代機械發(fā)展中高速、精密的主要特征,同時提高機械的動力性能,必須對機械的平衡問題進行深入研究,探求減小慣性作用的不良影響,改善機械動力品質的新方法。 本文通過對國內外平衡方法的研究,提出通過引入控制系統(tǒng)來主動地平衡機械的慣性作用,同時將主動平衡裝置與減速器進行集成設計,得到兼具平衡與減速功能的新型平衡裝置。 首先基于鄰接矩陣與圖論表示對兩自由度差動輪系進行概念設計,確定了基于2K-H型差動輪系的研究對象,提出了主動平衡減速器的選型原則。 然后以平面單自由度剛性機構的平衡為目標,對主動平衡減速器進行了運動學與動力學分析,基于此結果對主動平衡減速器進行了結構和控制參數(shù)的分析與優(yōu)化設計,驗證了主動平衡減速器在改善機械動力性能和獲得更佳平衡效果方面的可行性。 最后,對主動平衡減速器試驗臺進行了結構設計,對主要零部件進行了選型和設計。同時設計了機構的控制系統(tǒng),并對其后續(xù)實驗提出了幾種實驗方案。 本文工作將為動力平衡的新方法的后續(xù)研究與發(fā)展提供理論和設計基礎。
[Abstract]:Abstract: with the continuous pursuit of high productivity in modern society, the operation speed of mechanical equipment is increasing, and the consequent inertia effect is obviously increased, and the resulting vibration, noise and other problems seriously affect the working performance and service life of the machine. In order to adapt to the high speed in the development of modern machinery and equipment, the main features of precision are improved at the same time. The dynamic performance of machinery must be studied in depth to find out a new way to reduce the adverse effects of inertia and improve the dynamic quality of machinery.
Through the study of the balance method at home and abroad, this paper puts forward that the control system is introduced to actively balance the inertia of the machinery. At the same time, the integrated design of the active balance device and the reducer is carried out, and a new balance device with the function of balance and deceleration is obtained.
First, based on the adjacency matrix and graph theory, the concept of the two degree of freedom differential gear system is designed, and the research object based on the 2K-H differential gear train is determined, and the selection principle of the active balance reducer is put forward.
Then the kinematic and dynamic analysis of the active balance retarder is carried out with the objective of the balance of the plane single degree of freedom rigid mechanism. Based on this result, the structure and control parameters of the active balance reducer are analyzed and optimized. It is proved that the active balance retarder can improve the mechanical dynamic performance and obtain better balance effect. The feasibility of the aspect.
Finally, the structure of the active balance retarder test rig is designed, the main parts are selected and designed, and the control system of the mechanism is designed, and several experimental schemes are put forward for the follow-up experiment.
This work will provide theoretical and design basis for further research and development of new methods of dynamic balance.
