Embodiment Construction
[0019] See figure 1 , figure 2 , Figure 6 and Figure 7 , establish an effective 3D grid model for automotive air conditioners and air ducts, use the above 3D grid model for CFD analysis, and calculate the air volume distribution of each air duct inlet from the analysis results; view Figure 6 The wind speed nephograms on each windshield are shown to see the coverage area of the wind blown from the outlet of the air duct on the windshield.
[0020] According to the results of CFD analysis, first adjust the air volume distribution of the air duct inlet, and adjust the length of the air duct inlet (see figure 2 and image 3 ) L1, L2, L3, L4 and the cross-sectional areas S1 and S2 of the left and right air ducts are used as design variables, and only one variable is changed each time. The general air volume distribution ratio is 1:4:4:1, but due to the The wind generated by the outlet is not evenly distributed, so the cross-sectional area of the air duct inlet is diff...

The invention relates to a method for designing automotive upholstery, and particularly relates to a computer simulation design on a duct of an automobile air conditioner. The invention aims to provide a method for designing a defrosting duct of an automobile air conditioner, which is high in design efficiency and can shorten the duct development cycle. The method for designing a defrosting duct of an automobile air conditioner is implemented by using a CAE emulation technique, and comprises the following steps: 1) modeling: building product data provided by a design engineer into a closed mesh model by using modeling software; 2) CFD analysis: carrying out steady-state defrosting analysis on the model built in the step 1 by using analysis software; 3) optimized analysis: according to CFD analysis results, optimizing an area which does not reach the standard, setting a design variable, and getting a floating range; 4) editing an objective function according to the design variable preset in the step 3), and carrying out optimized analysis; and 5) model transformation: transforming the optimized mesh model meeting the requirement into three-dimensional data, and carrying out object manufacturing. The method disclosed by the invention has the advantages that the optimization of design variables is realized by using computer software, the variables are clear and objectives are clear, so that a CAE engineer and a design engineer can cooperate for achieving the purpose of design optimization in a short time as far as possible.
Description
technical field [0001] The invention relates to a design method of an automobile interior decoration, in particular to a computer simulation design of an automobile air-conditioning air duct. Background technique [0002] The performance of a car not only includes its power and economy, but also its functionality and comfort. Especially in the case of rainy days in summer or frost in winter, its defrosting and defogging functions appear particularly prominent. If the defrosting effect of the car is not good, it will seriously affect the driver's line of sight, and there will be hidden dangers in driving. If the wind blowing from the air outlet is unevenly distributed or the temperature is uneven, it will make the occupants feel uncomfortable, so the distribution of air volume is still very important. The traditional design method is that design engineers rely on their own experience to optimize the structure, which is time-consuming and labor-intensive. Contents of the i...
