摘要
针对低温LNG装卸撬转运灵活性差的问题,设计一种车载液压驱动单剪叉式全向移动升降平台。利用三维建模软件SolidWorks对全向移动升降平台进行三维实体建模,通过有限元分析软件Ansys Workbench建立有限元分析模型,对其在最高处和初始状态时受力部件升降平台、单剪叉臂以及底盘构成的整个车架进行静力学分析,并校核各部件强度。最后通过结构优化设计提高低温LNG装卸撬的灵活性,解决了低温液化LNG固定式装卸撬不利于运输和移动、机动性差、转运效率差的问题,为低温LNG装卸撬全向移动平台的研究提供理论基础。
Aiming at the transfer problem of low-temperature LNG loading and unloading skid, a vehicle mounted hydraulic driven single scissor type omni-directional mobile lifting platform is designed in this article. The three-dimensional modeling software SolidWorks is used to carry out the three-dimensional solid modeling of the omni-directional mobile lifting platform, and the finite element analysis model is established through the finite element analysis software Ansys Workbench. The statics analysis is carried out on the lifting platform, the single scissor arm and the whole frame composed of the chassis, which are the stressed components when the lifting platform rises to the highest position and the initial state;and then the strength of each component is checked. Problems that the low-temperature liquefied LNG fixed loading and unloading skid is not conducive to transportation and movement, as well as the poor mobility and poor transfer efficiency are solved through improving the flexibility of low-temperature LNG loading and unloading skid;it provides a theoretical basis for research on the omnidirectional mobile platform of the low-temperature LNG loading and unloading skid.
