A Novel Dynamic Calibration Method for Dynamic Characteristics Testing of Hydrodynamic Journal Bearing
The traditional dynamic calibration method for dynamic characteristics testing of hydrodynamic journal bearing is difficult to guarantee the consistency of the calibration condition and test condition and is hard to achieve. This method can affect the precision and accuracy of test result directly. So a novel method was put forward to solve this problem in this paper. Its core is to directly adopt the test bearing as the attached mass block to calibrate the test system, and then the frequency response function for each channel of test system under specific conditions can be got based on the related algorithm. Following, the implementation procedure and key technologies of the new method were introduced in detail. Finally, it is shown by an example that the proposed method is feasible.
