摘　　要：介绍了一种采用拍式感压片而无需在列车表面开测压孔的新的实车表面压力测量方法 ,并对试验中比较压的选取进行了详细分析。 2次实车试验得出的准高速列车表面压力分布规律一致 ,其结果对检验列车局部外形的合理性及空调设备进排风口位置的合理布置具有指导意义。A new measurement method for surface pressure on cars,with which the beating type pressure sensor of sheet shape is applied instead of making pressure measurement holes on surface of train,is described,and the selection of comparative pressure in the test is analyzed in detail.The distribution patterns of surface pressure on quasi high speed trains obtained in the two tests with cars are identical,the result has directive meaning in checking the reasonableness of partial contour of train and the reasonable arrangement of air inlet and outlet openings in the air conditioning equipment.
