Abstract
Based on the virtual prototype technology, using the ADAMS vibration analysis module, the displacement response rule of the main mechanism of the cutting system excited by sinusoidal harmonic excitation is obtained. And through the analysis of the results, the fact that 20HZ, 29HZ, 120HZ and 134 HZ are the sensitive frequency of the main mechanism is found out. Using the hammer test modal analysis methods to analysis cutting system of EBZ-75 type boom-roadheader, and compared with simulation results, the sensitive vibration frequency in vertical direction of the cutting system is achieved, which provides a test reference data for the optimize design of the cutting system.
