Stress Analysis and Design of High Speed Angle Centrifuges

A detailed graphical method for determining mechanical stresses in high speed angle centrifuges is explained and equations convenient for obtaining approximate values are presented. Various points of design are discussed, and stresses have been determined for several typical rotors to serve as guides for the designer. Theoretical considerations indicate that a properly designed rotor having a diameter of 20 cm and accommodating several hundred cubic centimeters of fluid can operate at speeds up to 50,000 r.p.m. for thousands of runs.
