Sentence examples for structural unbalance from inspiring English sources

Structural unbalance of the pumping unit (lbs).

The change in structural unbalance, SU, with crank angle is also disregarded.

The unit's structural unbalance is SU = −1500 lb, the torque factor calculated at the given crank angle is TF = 78.2 in; rod torque is found from Eq. 1, because the unit has a conventional geometry T_{text{r}} = 7 8. 2 left( { 1 9, 6 1 7 + 1 500} right) = 1 6 5 1;{text{k}};{text{in}};{text{lbs}}.

Structural instability.

Fig. 10 a Cross-couple structure during unbalance load.

The procedure for the computation of these structural matrices and the unbalance force vector is described in detail.

However, BBB dysfunction or damage to any structural BBB elements would likely unbalance the fragile CNS equilibrium.

Then we study the effect of the structural parameters (natural frequency and the flap static unbalance) of the control surface on the transonic flutter system.

When the rotor and the bearing pedestal structure frequencies are tested closer to operating frequency, it is probable that structural response could increase monotonically due to instantaneous step change in mass unbalance forces leading to structural degradation and catastrophic damage if the machine continues to operate.

Such a formulation of the optimization problem leads to the optimal design that combines an acceptable structural weight with the robustness with respect to uncertainties of residual unbalances – the main source of bending vibrations causing the rubbing effects.

In this study, the effects of the structural BTC on the flutter are investigated by considering the layup unbalances (ply angle, material and thickness of the composite laminates) in the NREL 5-MW wind turbine rotor blade of glass fiber/epoxy [02/+45/−45]S laminates.
