Key Technique In The Design And Manufature Of 350t Capacity Well-hole Wagon

Well-hole wagon is applicable for the transport of out-of-gauge and overweight cargos, such as the transformers, generators, rolling mills, reactors, and high-pressure boilers, etc. Developing heavy-duty well-hole wagon is one of the urgent needs of national economy development. A well-hole wagon has the characteristics of low tare weight, high transport capacity, high speed, multi-functional, and easy to assemble and disassemble. Based on many years experience of developing and researching on long-large (oversized) wagons, this paper presents a series of development and research work of a well-hole wagon with maximum transport capacity of 350t.The 350t transport capacity ranks the first among wagons of the same type that are currently available domestically. In the first part of this paper, a brief review of the research status of well-hole wagon both domestically and abroad is first introduced. Then, the development trend, and key development technologies of well-hole wagon is presented. It summarizes the key particularities in the development and research of a well-hole wagon. In the second part, this paper presents a detailed load distribution (or weight loading) analysis on the 350t well-hole wagon as a whole; describes the finite element model developed according to its particular characteristics, and the optimization of this model. After analyzing and pinpointing the key issues in the manufacturing technologies and assembling processes of the side load bearing assemble, it presents solutions, which includes the controlling of key processes during manufacturing and assembling, to bring the product quality to the level defined in the design specification.
