Movement Simulation and Analysis of Hydraulic Support Based on Virtual Prototyping Technology

This paper shows the importance of the performance of the hydraulic support and the characteristics of the virtual prototype technology. Using the three-dimensional modeling software Pro/E, the solid modeling of the hydraulic support is made and is imported into the multi-body dynamics software ADAMS. Dynamic simulations with the ADAMS software of the hydraulic support are carried out to obtain the dynamic characteristics of the hydraulic support. The movement of the four bar linkage and the track of the top beam end and the relationship between the top beam displacement and the roof force during the raising and falling periods of the hydraulic support are obtained and verified. The performance of the dynamic model of the hydraulic support is evaluated through the simulation of the whole motion process of the hydraulic support. The establishment of a digitized prototype for the hydraulic support may reduce the design cycle time as well as improve the design quality, which is helpful for the optimization design of the hydraulic support.
