DEVICE AND METHOD FOR MEASURING RIGIDITY OF BEARING OF ACTUAL SHAFT SYSTEM WHICH MEASURE THE RIGIDITY OF BEARING WITHOUT DISASSEMBLY

摘要

PURPOSE: A device and a method for measuring rigidity of bearing of actual shaft system are provided to measure the rigidity of a bearing, which supports an actual shaft system, without disassembly by using a modal test. ;CONSTITUTION: A method for measuring rigidity of bearing of actual shaft system is as follows. The calculated rigidity of bearing value is inputted in an analysis program. The natural frequency of a shaft system is calculated by the analysis program. A modal test device is established in the shaft system. The impact is inputted for the modal test. The natural frequency of the shaft system is measured by the modal test. The natural frequency calculated by the interpretative program is compared with the natural frequency measured through the modal test.;COPYRIGHT KIPO 2011
