    Abstract: Taking the spur gear as the object of study, based on the dynamic analysis of gear transmission system, the dynamic stress intensity factors of cracked gear teeth are studied by using ANSYS software. The calculation of dynamic stress intensity factor is realized by ANSYS parametric design language. Firstly, the involute tooth profile equation and t... Show More

    Abstract: Weld failure due to vibrations can be minimized if appropriate measure is implemented to ensure forced vibration is not equal to the natural frequency of the material. This research focuses on determining the optimum butt welded joint, by analyzing the various natural frequencies and mode shape response obtained from five different types of butt jo... Show More
  • Geant4 Based Space Radiation Application for Planar and Spherical Geometries

    Abstract: A space radiation application is developed based on Geant4 tool kit. Even though there are many space radiation applications like MULASSIS (MUlti-LAyered Shielding SImulation Software); the application developed here offers more flexibility in choosing the physical models. It can be used to analyze the spherical geometries directly in addition to t... Show More
