Thermal Characteristics of the Spindle-bearing System of Small Size Mill Center
This article discusses the thermal characteristics of the spindle-bearing system of small size mill center with COSMOS software.During the analysis process,it calculates the spindle boundary conditions: bearing heat and heat transfer coefficient.It also defines the spindle constraint condition and load condition which are in keeping with the actual processing situation.The following are analyzed such as steady temperature field,transient thermal effect,and thermal deformation,which provide the theory basis to optimize the design.
Abstract This paper presents the results of experimental study of gas turbine rotor of Air craft, Marine, wind turbine rotor etc. The natural frequency of gas turbine rotor using Holzer’s method same are compared with the results that are obtained through a well known software based approach of FFT Analyzer. Rotors employed for transmitting motion are manufacturing using mild steel as it offers better stiffness and economical conditions under damping conditions. Mild steel as it resists tortional loads and bending loads more efficiency are more effectively. In this paper natural frequency of the gas turbine rotor predicted according to numerical results will be compared with experiential results.
