Rotary Vibration Control Simulation and Experiment Research on the Boom of Concrete Pump Truck
According to rotary vibration at the end of the concrete pump truck boom,analysis of the boom rotary vibration mechanism is carried out.Rigid-flexible coupling dynamics model and vibration control co-simulation model of the boom system are established.The analysis of the dynamic model solution shows that the simulation rotation vibration displacement curves at the end of the boom are coincided with the experiment result without control.The simulation and the experiment of the rotary vibration attenuation time are respectively 55s and 48s in the horizontal posture,and damping ratio are 0.0267 and 0.031 respectively.By vibration control co-simulation analysis and experimental verification,the simulation and experiment rotary vibration attenuation time at end of the boom are 17s and 13s respectively with control,and damping ratio are 0.2565 and 0.2871 respectively.Vibration attenuation time is shortened by more than 70%and damping ratio is increased more than 9 times,obtaining a good damping effect.
