Simplified rotor force calculation method of screw compressors
In order to help engineers or designers to perform rotor force calculation of screw compressors to satisfy the requirements of rotor strength check,bearing selection and bearing life calculation,a simplified rotor force calculation method of screw compres-sors is proposed and verified by computational fluid dynamics method.The results show that under different working conditions,the error of the simplified calculation method for the prediction of radial force is basically within 8.0%,and the maximum error of radial force under individual working conditions is 11.4%and the error of axial force prediction is within 5.0%,thus the simplified model can meet the requirements of engineering application.
