Method for checking temperature fields of automobile front cabin in layout stage

Abstract

The invention provides a method for checking temperature fields of an automobile front cabin in a layout stage. The method for checking the temperature fields of the automobile front cabin in the layout stage includes computing to obtain space temperature fields of the exhaust side of an engine in the front cabin through engine heat source temperature boundary conditions and a space lattice model after the engine is selected, converting the space temperature fields into space temperature distribution data files after the space temperature fields are processed, providing the space temperature distribution data files to a finished automobile front cabin layout engineer, inputting materials and coordinates of each component in the front cabin wanting to be subjected to temperature checking by the layout engineer to obtain a temperate value of the component at the position, comparing the temperature value to a corresponding temperature limit, and changing layout positions and temperature-resistant materials and performing heat insulation treatment and the like if the temperature value exceeds the limit. By the aid of the method, temperature field checking can be performed in the automobile layout stage, so that hidden automobile front cabin temperature field risks can be discovered as early as possible and prevented. In addition, the method for checking the temperature fields of the automobile front cabin in the layout stage is high in computing speed of early-stage simulation and extremely convenient to use.

Description

technical field [0001] The invention relates to a method for checking the temperature field of the front cabin of an automobile, in particular to a method for checking the temperature field of the front cabin of an automobile in a vehicle layout stage. Background technique [0002] With the continuous development of automobile technology, the degree of strengthening of the engine is getting higher and higher, and the layout of the front cabin is also more compact. Especially for cars with front-engine front-drive and exhaust on the rear side of the engine, it is difficult for the cooling air to enter the engine compartment through the air intake grille to cool the exhaust manifold and the components around the engine, causing the air in this area. The flow rate is low, the heat dissipation is not smooth, and it becomes a high temperature area. Many non-metallic components such as phase sensor, drive shaft sheath, etc., the working temperature in the front cabin often exceed...

AI Technical Summary

Problems solved by technology

Since the entire layout plan has been determined at this time and the design has been basically frozen, these methods are difficult to solve the problem fundamentally, and if it is necessary to modify the components that do not meet the temperature limit, the cost is high and the simulation cycle is long, which directly affects the project. Development progress; some problems are not solved at all
