電動角磨機(jī)動態(tài)響應(yīng)與噪聲分析
[Abstract]:Electric angle grinder (including gear pair, rotor, stator, bearing, gear box, shell and other parts) is one of the important sources of vibration and noise. Especially when rotating at high speed, the vibration and noise caused by the collision between the parts and components bring a certain amount of physical and mental harm to the long-term users. How to effectively reduce vibration and noise has been a research topic of researchers. The finite element modeling and numerical analysis of dynamic response and noise of small high-speed electric angle mill are carried out in this paper, and the experimental results are verified. The experimental results verify the validity and correctness of the finite element model and numerical simulation algorithm. The main contents of this paper are as follows: (1) Modal analysis of the whole model of electric angle mill, the first 10 natural frequencies and their natural modes of the whole model of electric angle mill are analyzed. (2) transient analysis of the whole model of the electric angle mill, the dynamic response characteristics of the whole model of the electric angle mill under the condition of no load, (3) the meshing collision analysis of the gear pair of the electric angle mill, The meshing stress of the gear pair of the electric angle mill at the beginning of meshing is calculated. (4) the noise analysis of the whole machine model of the electric angle mill is carried out and the distribution of the sound field on the spherical surface around 4 m of the whole model of the electric angle mill is analyzed. (5) the vibration and noise experiments of the electric angle mill are carried out to verify the validity of the finite element model established for the electric angle mill and the results of the dynamic response and noise radiation numerical analysis of the electric angle mill.
