The results of DEM show that the crosstie rotations would increase the acceleration of individual ballast particles and contact forces between ballast particles.
As can be seen from this data, increasing the acceleration of the traps toward |a trap|=2×107 m/s2 leads to a reduction in the intensity of the time-of-flight signals.
However, passive friction dampers are well-known for having a highly nonlinear hysteretic behavior caused by stick-slip motion at low velocities, a phenomenon that is inherent in friction and increases the acceleration response of the structure under control unfavorably.
On the contrary, the installation of PSDs increases the accelerations as compared to that of uncontrolled system.
The test results demonstrate that, for a rigid superstructure, the viscous damper is able to effectively suppress the peak isolator displacement induced by the long-period pulse component without increasing the acceleration level of the superstructure; however, it also slightly increases the structural acceleration in the seismic excitation without the pulse component.
Increasing the acceleration and deceleration of trains within a railway network can improve the performance of the system.
This relationship can be deterministic, as when the increase in the charge on a plate causes a corresponding increase in the acceleration of a test particle; but it can also be probabilistic, as when an increase in the amount that an individual smokes increases her probability of lung cancer.
And we have very little to show for it except for a increase in the acceleration of the climate change phenomenon".
The bent pipes caused both turbulence and kinetic energy to increase, resulting in the acceleration of the reaction rate.
Increased variability in the acceleration of the head and in the transmission ratios suggest a potentially destabilizing effect of load carriage on the head trajectory.
