Calculation of random wave parameters using regression method
(КНУБА, 2015) Dang Xuan Truong
This research introduces a new method to calculate the parameters of random waves. Here we calculate the wave height and period. The process observation data from multiple waves of different conditions is a complex problem for the designers of offshore structures. The regression method is proposed as a new method with high reliability to solve this problem.
A method of determining the coordinates of the stiffness center and the stiffness principal axis of the vibrating system with damping
(КНУБА, 2014) Dang Xuan Truong; Tran Duc Chinh
The report presents a methodology to determine the directions of the stiffness principal axis (in this case subject to the linear displacement and forced rotation angle) of a solid object interact with the surrounding environment by resilient bearing supports. The results also show that determining the coordinates of the stiffness center in the vibrating system with damping factors is necessary in our research.
