J. Cent. South Univ. (2012) 19: 1399-1410 DOI: 10.1007/s11771-012-1156-5 Dynamic analysis of dam-reservoir-foundation interaction using finite difference technique M. Abdollahi, R. Attarnejad School...-foundation interaction was conducted using finite difference method (FDM). The Timoshenko beam theory and the Euler-Bernoulli beam theory were implemented to draw out governing equation of beam......
the real-time requirement. One-dimensional finite difference method could realize real-time control in the case of neglecting both the circumferential and radical heat exchange, but the over-simplified... method of alternating direction finite difference was introduced and discussed in the model’s stability, calculating speed and precision. Specific work roll after one real rolling unit......
were proposed and a numerical analysis model of the thermal crown of work rolls was established using finite difference method to study roll’s thermal deformation. Based on simulation results.... Therefore, this work has important value for on-line control of roll’s crown in cold rolling.Key words:cold rolling; finite difference method; thermal crown; control-efficiency factor......
