Research on Modal Simulation Analysis of Drop-bottom Mine Car Bogie Based on ADAMS
Bogie is an important component of mine drop-bottom car,and is used to change or restore their driving direction.To improve the static strength,fatigue strength,reliability and other performance of the bogie,SolidWorks software was used to establish a 3D solid model of the drop-bottom mine car bogie.Then,the 3D solid model was imported into the Vibration module of ADAMS software to calculate the first 19 fixed frequencies of the drop-bottom mine car bogie.Simulation analysis shows that the bogie vibration frequency forms a periodic vibration peak between 2.098 Hz and 2.347 8 Hz,leading to resonance phenomenon,and then the bogie vibration gradually tends to become gentle.Until a larger vibration peak is formed at 8.341 8 Hz compared to the previous one,and resonance occurs again.Afterwards,the bogie vibration gradually tended to be gentle.This results provide theoretical reference for subsequent optimization of bogie structure,smoothness research and improved design.
