【摘要】 根据司机室通风系统的结构建立有限元模型，并利用fluent软件对通风系统进行仿真分析，得出司机室内温度分布和速度分布情况。基于仿真结果对通风系统中的管道形状、送风口位置和样式进行了优化。编写udf程序，利用PID控制器根据室内温度变化自动调节送风温度，以实现室内温度的自动控制。本次仿真分析结果可为今后优化司机室的通风系统，实现室内温度的自动控制，提高司机室内环境质量等方面的进一步研究提供一定的参考。更多还原

【Abstract】 This paper establishes a finite element model based on the structure of the driver’s cab ventilation system and uses the Fluent software to simulate and analyze the ventilation system.The temperature and velocity distribution inside the driver’s cab are obtained.Based on the simulation results, the pipe shape, and the air outlet position and style in the ventilation system are optimized.A UDF program is written, and a PID controller is used to automatically adjust the air supply temperature according to the indoor temperature changes, achieving automatic control of the indoor temperature.The results of the simulation analysis can provide certain reference for optimizing the ventilation system of the driver’s cab in the future, realizing automatic control of the indoor temperature, and improving the environmental quality inside the driver’s cab.更多还原
