Step 4, the axis of the axis for generator terminal of calming the anger and turbine end is flexibly connected, flexible clutch can transmit torque without Transmit axial force；

Step 5, the air and lubricating oil pipeline of turbocharger be installed, completes turbocharger under self-loopa state not With the test of the axial force of revolving speed, turbocharger test of the axial force of different rotating speeds under self-loopa state is carried out herein Other peripheral test system and methods belong to the prior art, are no longer described in detail.

According to above-mentioned steps, the independent test for generator terminal axial force of calming the anger and the independent test of turbine end axial force are realized, Solve the problems, such as that the prior art cannot individually test compressor and axial turbine power.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
