2.1 heat transfer model
Within the injecting model and solidification phase, the model and metal solution mainly have three heat transfer methods, which are thermal radiation heat transfer, conversion of heat conversion, and heat transmission. In terms of heat -conducting heat transfer method, the heat transmission in metal liquid in solidification is very tedious and complicated, and then the key content of the analysis of aluminum alloy wheel casting analysis. During the solidification phase, the heat will be transmitted through three heat transfer methods, and the calculation is completed through the Fourier control equation.
2.2 Moral model
Assuming that under the fixed pressure, in the analysis of metal liquid motion characteristics, the dynamic conservation equation and non -compressed continuous equation can be described. In the casting type, the model calculation is mainly implemented by the Sola algorithm, and it is mainly composed of volume contracting and solution function. In the application, the solution method mainly corresponds to the force field and the speed calculation of the solution unit, but the volume function method can be calculated in the liquid flow.
2.3 Simulation results and discussion
After the aluminum alloy wheels, after the construction is completed, it assumes that the filling time is 0.6m/s, the temperature is 800 degrees Celsius, and the pressure is 20mma. In the calculation, the model is implemented with the help of the Sola algorithm, and then understands the actual situation of the charging type under different events and status. Under the prescribed conditions, the aluminum alloy wheels complete the integrated filling operation in 7s. After entering the wheel spoke in the wheels, the metal liquid enters the filling cavity, and finally completes the convergence operation at the lower end of the silver alloy wheels. Then it needs to set the flow slot device at the lower end of the hub. The overall temperature of the metal liquid is low. During the entire filling stage of aluminum alloy wheels, the flow rate of metal liquids is basically unchanged, and the metal liquid will not have a significant impact. The aluminum alloy model forms a relatively stable speed, the distribution of metal solution is very uniform, and at the same time, it is excellent.
