【摘要】：为解析自动印花机椭圆运动机构产生振动和噪声的原因,基于Creo软件完成了R680系列自动印花机台板及其椭圆轨道的建模与运动过程仿真分析;推导了求解椭圆运动机构最大振动位置的一般公式;探究了运动过程中滚轮与轨道的紧密性和减小噪声的相关问题。结果表明:由直线轨道进入半圆轨道过程中,自动印花机台板外前轮与轨道的间隙值呈现先快速变大、再缓慢变小和最后趋向于零的规律,外后轮与轨道的间隙值呈现先慢后快的滞后变化;由半圆轨道进入直线轨道过程中,外侧前后轮与轨道间隙值与台板进入圆弧轨道过程呈现对称现象;R680系列印花机台板在进入轨道过程中,外前轮转过约7.5°和17.5°时,外侧前后轮与轨道间隙分别出现最大值,皆约等于0.33 mm。
[Abstract]:In order to analyze the causes of vibration and noise caused by elliptical motion mechanism of automatic printing machine, the modeling and simulation analysis of the plate and its elliptical track of R680 series automatic printing machine are completed based on Creo software. A general formula for solving the maximum vibration position of an elliptical kinematic mechanism is derived, and the relative problems of the compactness between the roller and the track and the reduction of noise in the course of motion are discussed. The results show that the gap between the front wheel and the track of the automatic printing machine board first increases rapidly, then slowly becomes smaller and finally tends to zero in the process of moving from the linear track to the semicircle track. The gap between the outer rear wheel and the track is slow first and then fast. In the process of moving from semicircular track to linear track, the gap between the outer front and rear wheels and track is symmetrical with the plate entering into the arc track. When the outer front wheel turns about 7.5 掳and 17.5 掳, the clearance between the outer front wheel and the track appears the maximum value, which is about 0.33 mm..
