(redirected from vibration test)

The event of a price movement that approaches a support level or a resistance level established earlier by the market. A test is passed if prices do not go below the support or resistance level, and the test is failed if prices go on to new lows or highs.

The attempt by a stock price or a stock market average to break through a support level or a resistance level. For example, a stock that has declined to $20 on several occasions without moving lower may be expected to test this support level once again. Failing to fall below $20 one more time would be considered a successful test of the support level and a bullish sign for the stock.

Vibration tests - one of the many tests space-bound instruments are subjected to - are performed to ensure that spacecraft fit enough to tolerate the often hostile conditions they would have to face in space.
To guarantee the structural safety and successful on-orbit operation of the calibration mechanism in severe launch environments, launch vibration tests such as sine burst test, random vibration test, and shock test were carried out under qualification level.
In order to estimate amplitude-dependent parameters, the Random Decrement Technique was adopted in this study to process ambient vibration test data.
Using released method to carry out free vibration test on indoor test model cable, the acceleration signal got by acceleration sensor of cable span is shown in Figure 12, cable displacement signal obtained by the frequency domain integral method is shown in Figure 13, and the spectrum curve got after FFT on model cable free vibration displacement time history is shown in Figure 14.
Laboratory 6-DOF vibration systems represent the latest chapter in a long history of refining the accuracy of laboratory vibration tests. MDOF excitation and control systems continue improving and are standard equipment in many vibration test facilities.
