In order to prevent the phenomenon of vehicle leveling instability, the control system needs to adjust the air mass flow rates flowing into or flowing out of the air springs effectively during the vehicle height lifting or lowering procedures.
Among them, the vehicle pitch angle originated by the desynchronized height adjustment between the front and rear air suspensions in the height lifting process is illustrated in Figure 2(a), the vehicle roll angle originated by the desynchronized vehicle height adjustment between the right and left air suspensions in the height lowering process is illustrated in Figure 2(b).
If the vehicle body does not maintain at an appropriate posture, the control signals for the four air spring solenoid valves would be reassigned to reduce the air mass flow rates flowing into the air springs whose height lifting speed are relatively fast.
(The low and mid-height lifts, full of feeling and intimacy, are just as telling).
Owing to the void space at lower heights, lift-up buildings have high building permeability at ground level and subsequently improve the air circulation in congested urban areas.
Completely new dimensionless correlations for the plume heights, lift-off distances, and mean flame surface densities of atmospheric jet flames, in the absence of a cross wind, are presented.
The optimization criterion is construction cost and the decision variables are material types, placing temperature, the height of lifts and time intervals between lifts.
Concrete is usually cast (or poured) in separate, distinct blocks with heights (or "lifts") of no more than about 1.5 metres (5 feet).
Anders compensated for his height by lifting his chin, giving the impression of trying to keep his head above the water of tall people.
Extended to its full height, the lift clears the roofs of the East Campus dorms.
