Structure Design and Finite Element Analysis of 16T Partial Hanging Crane

Abstract After ten years of development, China's industrialization process continues to advance, from heavy industry needs further increased。 Partial hanging crane is the bridge type crane in the main type, it has the characteristics of space utilization rate is high, a large operating range, wide adaptability, versatility and。 Partial hanging bridge crane general consists of bridge, hoisting mechanism and the car run institutions, a cart running mechanism。 This design adopts 16 tonnage partial hanging bridge crane is studied。The full text is pided into 5 parts to complete this design topic content:

The full text is pided into four parts to complete this design topic content。 The first part is the introduction, which briefly introduces the function of lifting machinery, the development status and existing problems of domestic and international lifting machinery, and the development direction of China's lifting machinery。

    The second part is the determination of the overall structure, this part mainly analyzes the working characteristics of the crane, including lifting mechanism, the arrangement of the size of the vehicle, the connection between beam and the bracket。 

The third part for the main parameters of the crane design and checking, this part including overhead  such as cart track, the height of girder, end beam height, the stiffener layout size and computational load, box type girder, main weld checking。

The fourth part is the crane structure finite element analysis, this part introduces the basic principle of finite element analysis and its characteristics, the finite element analysis process includes modeling, meshing, loading, solving analysis 。

The fifth part is the conclusion and outlook section。 The design is analyzed and summarized。 The reliability of the basic size and finite element analysis of the bridge crane is demonstrated, and the deficiency of the bridge crane is also pointed out。
