运用三维建模软件Pro/E 对液压支架进行实体建模，并将其导入多体动力学软件ADAMS 中。运用ADAMS 软件对液压支架进行动力学仿真，获得了液压支架的动态特性。对液压支架升降过程中四连杆机构运动、顶梁端点的运动轨迹、顶梁位移与顶板力的关系等进行分析，验证了设计的合理性。通过模拟液压支架的整个运动过程，检验了液压支架动力学模型的性能。液压支架虚拟样机的建立可以缩短其设计周期并提高设计质量，有助于液压支架的优化设计。
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.
