The invention provides a high speed spindle system dynamics test device using gas excitation and a test method. An excitation device needs to excite each testing point, and excitation of multiple test points at different positions cannot be achieved if the excitation device employs a fixed installation mode. The device comprises a testing system (33) and further comprises a testing position change device (34) and a gas excitation device (32). The testing position change device is installed on a workbench (17) of a planer type numerical control milling center. The gas excitation device and the testing system are installed on the planer type numerical control milling center. The testing position change device comprises a testing position moving device (35) in the horizontal X direction, a testing position moving device (37) in the circumferential Z direction, and a testing position moving device (36) in the vertical Z direction. The invention provides the high speed spindle system dynamics test device using gas
