不同路面提梁机油气悬挂行走支撑系统的优化设计

Optimization Design of Oil Gas Suspension Walking Support System about Gantry Crane on Different Road

提梁机是高铁建设中所需箱梁的生产、架设的特殊大型施工设备。因自身重量和载重巨大,行走支撑系统对路面不平度的适应和衰减性能直接决定其行走时的稳定性和安全性。在不同路面情况下,通过对连通式油气悬挂系统动力学仿真和优化设计,得到的新型台车悬架系统优化选型方案,有效地缩短了提梁机行走支撑系统的研发周期,降低了开发成本,为提高产品设计和制造质量探索了新的途径。

Gantry crane is the erection of the box girder production,special large-scale construction equipment required in the construction of high-speed rail. Because of its own weight and huge load,walking support system of gantry crane adaptation and attenuation performance of road surface roughness directly determines the walking stability and safety. In different road conditions,through the dynamic simulation and optimization design of the connected hydro pneumatic suspension system,the optimal selection scheme of a new type of car suspension system was gotten. It can effectively shorten the development cycle of the supporting system of walking beam hoister,reduced the development cost,explore a new way to improve the quality of product design and manufacturing.
