Attack angle mechanism is a key part of the wind tunnel.The motion precision and dynamic characteristic directly affect the precision of the wind tunnel test because the mechanism support the test model .The design of the mechanism needs higher require. In this paper, the digit prototyping model are built and simulated in kinematics and dynamic by virtual prototyping.
