Since the angle between the heading and the seaway is different from 180 degrees, the action of the actuators for controlling the longitudinal dynamic (heaving and pitching) produces a coupling in the lateral (rolling) dynamic, and vice- versa.
This experimental campaign also comprised the direct measurement of dynamic pressures on both heave plates, a fundamental magnitude for the structural design, which, until now, had not been experimentally explored for this type of system.
But this time the water really comes thundering down, and, throughout the movie, Petersen has a dynamic feel for the rush and heave of the deluge, the pent-up energy, the sheer heft and momentum.
A CST soft drive system was used, in light loads or heave loads condition, the dynamic process of the loaded belt conveyor's soft start/soft stop can effectively be controlled to achieve a balance of power among various drives.
Model tests in waves have shown, however, that the dynamic effects of ship pitching and heaving motions in a seaway reduce the bending moment somewhat below that obtained by a quasistatic standard calculation.
Floor heave of a roadway is a dynamic phenomenon that often happens in the roadways of coal mines.
Then the kinematic and dynamic properties of the vehicle during large suspension heave motions are examined to establish guidelines for detailed mechanism design.
The dynamic modelling of the WEC describes the buoy heave motion with respect to its acceleration and is based on the second Newton's law.
A dynamic model was, therefore, developed assuming that the buoy heave motion is excited by the sea waves.
Measurements were carried out on the stationary cylinder and in four dynamic configurations, each characterised by different values of the heaving and pitching natural frequencies.
