aerodynamic force造句
Though asymmetry stator mistuned may result in bigger amplitude aerodynamic force with the same frequency as rotational speed, it could reduce effectively the aerodynamic force of blade as a whole.
An equipment of measuring aerodynamic force was designed and developed, and several bionic wings were tested on it.
Under cross wind action, vehicle-bridge coupling vibration analysis requires consideration of aerodynamic force parameters of vehicle and bridge deck.
The wind velocity of first order instability is obtained from the dynamic equilibrium relationship between aerodynamic force with dead weight and inertia force of membrane.
On the basis of static aerodynamic force tests and dynamic response tests, the galloping and (vortex-induced) oscillation performances of H-shaped booms were investigated.
The generalized aerodynamic force required in analysis is calculated by using horse shoe vortex— vibrational pressure doublet grid method, based on theory of subsonic unsteady lifting plane.
Computation of changes of aerodynamic force coefficients and its mechanism analysis under different oscillating conditions in lock-in status are given.
The results indicate that the higher the intensity of shock wave, the farther the dispersal distance, which proves that the aerodynamic force plays the leading part in the reaction processes.
An experimental study on the aerodynamic characteristics of New Concept Car is conducted by model wind tunnel test, covering the pressure coefficient and wake vortices on longitudinal symmetry plane, as well as aerodynamic forces and moments under different yaw angles.
The aerodynamic forces on the cars when they meet have significant effect on the car handling stability.
First, the basic theory which includes vortex convection, viscous diffusion, vortex shedding, aerodynamic forces formulas are presented. Then, the steps to use vortex method are presented.
When the train runs slowly, the aerodynamic forces acting on the box car decreases, which is helpful to the train passing safely the bridge of wind zone.
