Investigation of effects on the contact condition and the collision behaviour of a wheelset with a flat set on a roller rig by the shape at the edge of the wheel flat

Autor: Yasutaka MAKI, Yoshiaki TERUMICHI, Masataka YAMAMOTO, Katsuyoshi IKEUCHI

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 85, Iss 875, Pp 19-00003-19-00003 (2019)

We firstly executed bench tests of a bogie having the wheelset with a wheel flat installed on the roller rig. A wheel flat of 75 mm was prepared on the wheel tread and the front edge of the wheel flat was rounded by the grinding work. By making the r

Finite element simulation of surface cracks in T-shaped unilateral welded joints

Autor: Guo Yi, Meng Yunjiao, Wang Zhen, Zhang Youhong, Chang Xinlong, Qi Chongyang

Publikováno v: 2021 IEEE International Conference on Power, Intelligent Computing and Systems (ICPICS).

Aiming at the fatigue fracture phenomenon in the T-welded structure, the ANSYS finite element method is used to calculate the stress intensity factor of the crack, and the law of its change under different crack shape ratios is analyzed, and the law

Numerical and laboratory study of flows around a tilted plate

Autor: Iaroslav V. Zagumennyi, Yuli D. Chashechkin

Publikováno v: 2020 Ivannikov Ispras Open Conference (ISPRAS).

The structure and dynamics of flows near a tilted plate in stratified and homogeneous fluids are studied numerically and experimentally for various flow regimes. The numerical study is based on the fundamental system of equations, which allows calcul
