Abstract
Using mixed modeling of lumped parameter method and distribution quality method, mechanical model of rotor-bearing system is established .Based on Riccati transfer matrix method, the effect factors of gyroscopic moment, supporting stiffness ,shear deformation are taken into account, then a transfer matrix expression of mixed model was deduced. And a user-friendly, simple operation, strong expansion common rotor critical speed calculation program is developed with VB in this paper. Examples were used to validate the program as well. The calculation results are with high precision. The program is reliable with correct algorithm; it has a very high value in practical engineering.
