With the development of computer hardware and simulation software and the maturity of various finite element software, the application of
The design takes the tractor split axle housing as the research object. The axle housing is made of zg40mn low
When the molten metal is poured into the mold, the volume shrinkage will occur during cooling and solidification. This shrinkage
The numerical simulation of temperature field is the basis of ProCAST software simulation, and also the core module. Through the
In the filling process, the flow of molten metal will have a great impact on the quality of the axle
ProCAST casting computer simulation process: firstly, Creo software was used to establish the three-dimensional numerical model of the casting system
The gating system is the channel to guide liquid metal into the mold cavity in sand mold. Its structure is
Numerical simulation is a method that uses the correspondence between different things to verify measures. Numerical simulation is irreversible. Casting
Casting process parameters mainly include dimensional tolerance, linear shrinkage, draft angle and other aspects. The determination of these process parameters
The linear shrinkage of the bridge shell has a great influence on the accuracy of the size of the bridge
Generally speaking, the higher the pouring temperature is, the better the fluidity of alloy liquid is, and the more favorable
For sand mold casting, in order to realize sand molding, mold taking, pouring riser setting and sand core installation, the
The pouring position usually refers to the position of the axle housing in the mold when pouring. The pouring position
For cast steel, the main raw materials include scrap steel, ferrosilicon, manganese iron and aluminum alloy deoxidizer, and the main
(1) Scrap steel is the main raw material for casting smelting. Two samples are randomly selected from each batch for
The structural types of axle housing can be roughly divided into three types: open type, integral type and combined type.
The structural design of the axle housing can be roughly divided into the following aspects: the functional design of the
Taking the tractor split axle housing as the research object, the paper firstly analyzes the process of the overall structure
At present, most companies use sodium silicate sand mold casting and V-method casting process for production. In view of the
As the key part of tractor, the main research contents are as follows: firstly, analyze the process of axle housing
Since the 21st century, solidification numerical simulation technology has been developing continuously, and it is in the stage of optimization
In foreign countries, the analysis unit of “heat and mass flow analyzer” of Columbia University was first used in casting
Casting belongs to liquid metal forming technology. In actual production, casting engineers often make process according to previous experience, and
A certain type of broken axle housing of a company is mainly used for tractor load-bearing bridge, with an annual
