摘要
针对民用轿车引擎盖部位的温度分布做了详细的研究,提出了一种民用轿车引擎盖部位的温度场建模方法并建立了相应的温度场模型。首先以某国产品牌的东风标致民用轿车为研究对象,进行引擎盖温度场建模并优化模型。对比模型计算结果和实际试验结果,结果表明优化后模型计算所得的引擎盖温度分布和温度数值与实际的引擎盖情况有着良好的一致性。初步证明了建模方法和所建模型的合理性。为了进一步证明建模方法在不同品牌民用轿车中的有效性和通用性,将所建模型推广到另一品牌的福克斯民用轿车,模型计算结果和试验结果仍然有着良好的一致性。充分说明,所建模方法和模型不仅计算结果准确而且有着良好的通用性,具有较高的实用价值。
In this paper, the temperature distribution of the hood of a civil car was studied in detail. A modeling method for the temperature field was put forward and the corresponding temperature field model was established. First, a domestic brand of Dongfeng Peugeot civil car was selected as the research object to set up the hood temperature model and optimized the model. In contrast to the simulation and test results, it shows that the temperature distribution and temperature values of the hood calculated by the optimized model are in good agreement with the actual hood conditions. This preliminarily proves the rationality of the model and the modeling method. In order to further prove the effectiveness and versatility of the modeling method, the model was extended to another brand of Fawkes civil car. The calculated results of the model are in good agreement with the experimental results. This fully shows that the modeling method and model in this paper have not only accurate calculation results, but also good versatility and high practical value.
