The vertical acceleration

The effect of the asymmetric damper on the vertical acceleration of the driver’s body, suspension deflection and tire dynamic load were studied thoroughly in order to provide suggestions for choosing damping parameters while building a bus’s suspension system. The vehicle model with three DOFs exposed to random road profiles was employed to investigate the dynamic responses for both two cases of linear symmetric and two-stage asymmetric dampers.

The effect of the periodic oscillation of the gravitational field, known as g-jitter, on the free convection from a vertical plate is investigated in the present paper. The problem has been simplified by the laminar boundary layer and Boussinesq approximations. The fully implicit finite-difference scheme is used to solve the dimensionless system of the governing equations. The results for laminar flow of air (Pr = 0.72) and water (Pr = 7.00) are presented for different values of the amplitudes and frequencies of the g-jitter.

The main idea of this method is that the force of the controlled damping will change, so that the magnitude of the force is equal to that of the spring, but the direction of the forces is the opposite. This will reduce the vertical acceleration of the vehicle body. The simulation results in the time domain have been clearly shown by using the balance control methods. The root mean square of the vertical displacement, pitch angle and their accelerations decrease by 25-50%, compared to the passive suspension system.

This study aims to rigorously examine the influences of the vertically propagating recorded strong ground motions on the trapezoidal-shaped hills in different sizes and shape ratios. In order to generalize the results of the study, one-dimensional as well as two-dimensional analyses are conducted. Then, intended results are represented in dimensionless form as a result of which amplification ratio patterns are extracted and compared with each other in terms of displacement, velocity, and acceleration.

In this paper, we present a method to apply the exact linearization technique to the q-UAV without augmenting its dynamic model. For this purpose, using the vertical dynamic equation, the vertical position control input is designed separately so that the vertical acceleration is piecewise constant.

This configuration enables the rubber to be loaded in both shear and compression with the majority of engine rotational flexibility being carried out in shear. Vertical deflection due to body pitch when accelerating or braking is absorbed mostly in compression. Vertical elastic stiffness may be increased without greatly effecting engine roll flexibility by having metal spacer interleafs bonded into the rubber. Double inclined wedge with longitudinal control mounting (Fig. 1.
