Structural Optimization of Mine Hoisting Skip Underframe Based on Modal Analysis

Abstract:

Aiming at the problems of vibration and noise appeared in the work of lifting the skip underframe of the mine, a parameterized model of the underframe of skip is established by taking advantage of UG. And a finite element modal analysis is done by leading 3D model into the ANSYS, and the credibility of the finite element model is verified by combining the modal test. On the basis of comparing the characteristics of the external excitation frequency, the dynamic characteristics of the underframe of skip are evaluated and the structure is optimized. The results of the optimization indicate that: not only the modal frequency of the first eight orders of the ship underframe has avoided the range of external excitation frequency, with a smooth mode of vibration, avoiding the occurrence of sympathetic vibration effectively, but it has lost a weight of 10.6%, achieving an improvement of the hoisting capacity of the skip equipment. This research is of important reference to the technical transformation of skip equipment for some mine enterprise.
