Optimised Design of Belt Conveyor Drive Frame Structure
In order to solve the problem of easy damage of the belt conveyor drive frame,the static mechanics and vibration modal analysis using simulation software,found that the maximum stress value of the structure is 101.58 Mpa,the maximum deformation is 0.52046 mm,the overall structural strength,stiffness meets the requirements,but found that the frequency of the first six modal orders are less than the excitation frequency of the motor is easy to resonance damage.After the structural optimisation of the drive unit frame,the inherent frequencies of the remaining modes except the first and second order inherent frequencies are not less than the excitation frequency of the motor,which effectively improves the structural stability.
