Modal Analysis of the Frame of YlJ Series Tire Uniformity Testing Machine

Abstract:

A finite element model of the frame was established based on studying structure parameters of the YLJ series tire uniformity testing machine (TUTM). For the purpose of dynamic analysis of the frame of the YLJ series TUTM, make use of model analysis function of ANSYS to work out the first six-mode natural frequencies and vibration modes. Analysis results show that the first three-mode frequencies of the frame are 20.7 Hz, 21.9 Hz and 30.8Hz, which are far greater than working frequency of the spindle, 1 Hz. As is known, the natural frequency of the frame should be forty times more than the rotation of tire when the force variation of the tire is decomposed into tenth harmonic. In this situation, the low mode natural frequencies of the frame cannot meet this requirement, which have great influence on the test accuracy of the TUTM. The research results in this paper will provide helpful theoretical support to improve test accuracy of the YLJ series TUTM．
