| 针对总装装配线筒体类产品吊点位置不变、重心变化的特点，设计一种可调节吊具，通过调节链条长度适应不同的起吊工况。通过作图法计算链条长度，计算出链条的额定载荷。设计箱形吊梁、转接板结构及有限元分析，仿真结果满足使用要求，并通过加载试验验证。该研究结果可为同类吊具的设计、仿真、试验提供参考。 |

| Abstract: |
| Focused on the characteristics of fixed hanging point and changing position of gravity for the cylinder product in the assembly line, an adjustable spreader is designed, which can adapt to different lifting conditions by adjusting the length of the chains. The chain’s lengths are calculated by mapping method, and the rated load of the chain is calculated. The structure design and finite element analysis of the box girder and the adapter plate are carried out, and the simulation results meet the requirements of the use, which are verified by loading test. The research results can provide reference for the design, simulation and test of similar spreaders. |
