Abstract

The virtual prototyping assembly of hydraulic support was established using CAE technology. The investigation firstly tested the location analysis, namely, dynamic analysis of hydraulic support (ZY10500/20/36) for minerals is helpful to obtain the angle changes between roof beams and cover beam, and the movement test is concerned essentially with the different location and kinematics and dynamic analysis. In addition, this study investigated the model designed in motion the project meets the safety, reliability and stability claim through the motion curve. Especially, this work carried out kinematics and dynamic analysis to achieved the trajectory, velocity, acceleration curve, force and reaction curves of the hydraulic support beam within the safe range when load concentrated in the centre of the roof timber or under the condition of serval various loads, including the rated load axial loads and eccentric load , then found out the maximum stress and figured out the most dangerous place of the top beam under different loading ways, including partial load force, intermediate concentrated load, concentrated load at both ends. Additionally, this work examined stress distribution and dangerous part in the case of torsional loads. Consequently, this study ensured the safety and reliability of the whole equipment, and optimized the structure parameters to achieve coal mining mechanization. Moreover, this study provided a new way of thinking and theoretical reference to newly proposed relevant technical standard.
