摘要 设计了基于恒压法的汽车整车漏风量测试系统.采用标准孔板作为节流件,通过测量节流件上下游的压力差、干球温度和湿球温度等基础数据,经过计算可得到整车漏风量.在分析测量原理的基础上,详细给出了计算漏风量的公式和方法,并进行了实验.实验结果表明,该计算方法稳定可靠,可满足测量要求. An auto air leakage volume test system based on constant pressure method was designed. Using standard orifice plate as throttle device, after testing some original data such as the differential pressure between both sides of the throttle device, temperature of the dry-bulb and the wet-bulb, and so on, the auto air leakage volume can be calculated. The formulas and methods involved were demonstrated in detail and the experiment was designed based on an analysis of the measurement theory. According to the result of the experiment, this method proved stable and reliable and can satisfy the requirement of the measurement.
