【摘要】：裝載紗團(tuán)的光纜扎紗機(jī)在運(yùn)轉(zhuǎn)時,由于不平衡量較大會引起強(qiáng)烈振動,影響扎紗機(jī)的穩(wěn)定運(yùn)行。實(shí)際運(yùn)行中,紗團(tuán)是不平衡量的主要來源,并受到空間的限制,為此選擇球式自動平衡裝置對其進(jìn)行減振。利用傳遞矩陣法對紗團(tuán)轉(zhuǎn)子系統(tǒng)進(jìn)行分析,并對自動平衡裝置原理數(shù)值分析;將轉(zhuǎn)子系統(tǒng)和自動平衡裝置的計(jì)算模型融合,編制自動平衡裝置紗團(tuán)系統(tǒng)的MATLAB數(shù)值仿真程序。將已知不平衡量設(shè)置在不同位置,比較自動平衡裝置的平衡效果。利用有限元法模擬不平衡量在不同位置時的轉(zhuǎn)子系統(tǒng)穩(wěn)態(tài)響應(yīng)。有限元模型及數(shù)值仿真驗(yàn)證結(jié)果均表明利用自動平衡裝置可以達(dá)到有效減振的效果。
[Abstract]:During the operation of the optical cable binding machine loaded with the yarn ball, the strong vibration will be caused by the large unbalance, which will affect the stable operation of the yarn binding machine. In actual operation, the yarn ball is the main source of unbalance and is limited by space. Therefore, the ball automatic balancing device is chosen to reduce the vibration. The transfer matrix method is used to analyze the yarn ball rotor system, and the principle of the automatic balancing device is numerically analyzed, and the calculation model of the rotor system and the automatic balancing device is combined to compile the MATLAB numerical simulation program of the yarn ball system of the automatic balancing device. The known unbalance is set in different positions to compare the balance effect of the automatic balancing device. Finite element method is used to simulate the steady-state response of rotor system at different positions. The results of finite element model and numerical simulation show that the automatic balancing device can effectively reduce vibration.
