Sentence examples for poor vibration from inspiring English sources

Thus, any control technique to be implemented has to tackle stability problems (caused by the low frequency response of the actuators) and stroke and force saturation, which might lead to poor vibration cancellation performance.

The heavily damped vibration isolators result in poor vibration isolation over the high-frequency span which typically contains resonant frequencies for critical internal components and, therefore, are insufficient for maintaining a fail-safe vibration environment for electronic equipment.

The on-off control policy improved the performance of the seat suspension when end-stop impacts would otherwise occur with high magnitude inputs, without causing poor vibration isolation with low magnitude inputs.

Calculating with 50% more falls among patients with poor ability to stand in tandem stance [ 14] and with poor vibration sense in the lower limb [ 13], a power of 80% and the significance level set at 0.05, a sample size of 60 patients was required [ 28].

A higher VPT at the medial malleolus, indicating poorer vibration sense, was found after compared with before treatment.

The diagnostic confirmed that the concrete was of low strength and showed many shortcomings such as inappropriate mix design with respect to coarse aggregate size of concrete resulting in honeycombing, construction errors such as lack of cover and the use of low slump concrete, poor placement and inadequate vibration.

36 40 Fair (flow aid not needed) IV. 41 45 Passable (may hang up, flow aid might be needed) V. 46 55 Poor (agitation or vibration needed) VI. 56 65 Very poor VII.

When the stiffness measurement accuracy is undesirable because of poor noise reduction in vibration displacement and vibration acceleration signals, the vibration energy storage ability or real-time electrical signals (voltage, power, etc).

In such high feedrates and accelerations, even a small discontinuity in curvature or in tangency can result in jerk spikes and consequently in machine vibrations, poor cut quality and decreased lifespan of the equipment.

However, TMDs have relatively poor robustness, and their vibration control effect significantly decreases with drift of the structural vibration frequency.

Changes of timing between charges may result in an altered firing order and failure of the blasting sequence, which can cause high vibration levels, poor fragmentation, and/or an undesirable rock mass movement direction.
