In the above equations, the vehicle side-slip angle [beta] and the yaw rate r are the two state variables.
The steady-state value of vehicle side-slip angle in terms of yaw rate is given by,
This modification is due to the fact that when side-slip angle converges to zero, yaw rate can be reduced to a first-order lag.
The control law is described below, where is the sliding surface, is the yaw rate, is the controller variable and is the actual side-slip of the vehicle.
Side-slip control to stabilize vehicle lateral motion by direct yaw moment.
t] are the side-slip angle at the respective center of gravity (CG) of the car and the trailer, [h.
The nonlinear stability analysis based on the phase-plane method examines the set of relation between: (1) the leading unit's side-slip angle and side-slip angular velocity ([[beta].
Figures 2 and 3 show the phase-plane trajectories of the side-slip angle and side-slip angular velocity of the car and the trailer, i.
For the CT system, the relationship between the yaw motions of the car and the trailer is governed by Equation (12), implying that the side-slip angle of the car and trailer, the yaw rate of the car and trailer, and the articulation angle between the two vehicle units are interrelated.
Figures 5 and 6 show the 3D phase-plane trajectories interrelating the side-slip angle of the car and trailer, the yaw rate of the car and trailer, and the articulation angle between the car and the trailer.
Aircraft Interior Solutions developed a name for itself for seat cover work, which provided the gateway to landing the deal to assemble the side-slip seat.
The staggered side-slip design, which locks in place, also features a slightly larger 20-inch-wide middle seat with two armrests while its neighbors only have one.
Side-slip seat production includes machined parts from Primus Aerospace of Lakewood, Colorado; sheet metal components from Cutting Dynamics in Avon, Ohio; cushions produced by Chestnut Ridge Foam in Latrobe, Pennsylvania; and seat belts courtesy of the Takata Protection Systems plant in Torrance, California.
Assembled with the addition of the seat covers by Aircraft Interior Solutions, the completed side-slip units will be shipped out from North Little Rock.
The coming changes represented by the side-slip deal will introduce a regular production cycle at Aircraft Interior Solutions.
