The finite element method has been increasingly adopted to study the biomechanical behavior of biologic structures. Once the finite element mesh has been generated from CT data set, the assignment of bone tissue’s material properties to each element is a fundamental step in the generation of individualized or subject-specific finite element models. The aim(More)
Cylindrical roller bearing is often used in aeroengine main-shaft system because of its excellent capability working at high speed and heavily loaded condition. With the promotion of aeroengine performance both the higher speed and higher temperature etc., the dynamic working performance of the bearing attract more and more researcher's attention. This(More)
This paper attempt to achieve a more accuracy simulation of high speed cylindrical bearing cage's dynamic performance. Considering the flexibility of cage, dynamic equations of cylindrical roller bearing in high speed in main-shaft of aero-engine was established using modified Craig-Bampton substructure mode synthesis method. Rigid-flexible dynamic(More)
