Scope

TCSAE 146-2020 is the English-translated version of 汽车整车空气动力学风洞试验气动力风洞试验方法.

TCSAE 146-2020 — This standard specifies the requirements for the flow field quality, test equipment and instruments for the aerodynamic wind tunnel test of the whole vehicle, and recommends the aerodynamic test Standard operating conditions and test methods and procedures give an evaluation method for the validity of the test data, and the results obtained can be used as the aerodynamics of the whole vehicle the basis for evaluating and optimizing the design.

This standard applies to real vehicles, namely passenger cars and light pickups with less than seven seats (including seven seats), and also applicable to vehicle models of corresponding sizes (Clay model, hard model, etc.), the weight and size are determined according to the wind tunnel scale and test capacity.
