Horizontal swing movement parameters optimization design of longitudinal road header
Abstract：Mathematical model between hydraulic piston rod expansion capacity and horizontal swing velocity was built during the horizontal swing movement of the road header.Theoretical velocity was derived from unit energy consumption reverse method,and its value range was estimated.By using Matlab software,load curves of different horizontal swing velocities was calculated.The road header’s rigid-flexible coupling model was built in multi-body dynamics simulation software ADAMS and dynamic simulations were done under different velocities and load cases.Take productivity of road header,reliability and lifetime of gyration platform as constraint conditions,the velocities of horizontal swing movement were optimized.The results show that on the premise of gyration platform working reliably,when the expansion speed of piston rod is 2.887 mm/ s,namely horizontal swing velocity is 1.106 m/ min,the road header gets the economical cutting.
