阳光照射下汽车内部件温度的数学模型
Mathematical model for temperature of parts inside automobile under sunlight
摘要
Abstract
Due to the greenhouse effect,the car interior temperature is often higher than the ambient temperature under sunlight.To study the variation of the temperature inside the vehicle under sunlight,a solar radiation model was built based on astronomical theories.The mathematical models of the car seat,dashboard,air and glass were established with mechanism modeling method.A multi-point temperature wireless acquisition system was designed based on STC89C52 microcontroller and DS18B20 temperature sensor to measure the temperature inside cars.The correctness of the mechanism mathematical model was verified in comparison with temperature data.Based on this,a transfer function model of the car interior temperature under different solar radiation conditions was established.It provides a foundation for study on the car interior temperature control.关键词
