Dynamic Modeling and Simulation Analysis of Paver Ironing Device
In order to optimize the design parameters of the paver ironing device and provide a better construction operation strate-gy,the paver ironing device is modeled,simulated and experimented.The process of elevation angle α change during paving thickness adjustment is described in detail.The force analysis of the paver ironing device is carried out,and the dynamic model of the ironing device is established with the elevation angle α as a parameter.The Simulink block diagram is built with MATLAB to simulate the dynamic model.The influence of the width of the bottom plate of the ironing device,the vertical distance between the traction point O and the bottom plate,and the size of the force arm of the gravity G around the traction point O on the paving performance are analyzed.The simulation and experimental results show that the established dynamic model can correctly reflect the working principle of the ironing device.Increasing the width of the bottom plate of the ironing device can improve the sensitiv-ity of the leveling system,and using the manual adjustment mechanism to adjust the initial working elevation angle can effec-tively avoid the occurrence of a negative elevation angle without losing sensitivity.The conveying system,the distributing system and the walking system must work together and match each other to keep the material level constant,which is conducive to improv-ing the planeness of the paved road.
