Vibrations

Reducing vibrations If your S7-300 modules are exposed to severe shock and/or vibrations, you must take the appropriate measures to reduce the acceleration and/or amplitude, respectively. We recommend that you install the S7-300 on vibration-damping materials (for example, rubber-metal antivibration mountings). Ambient mechanical conditions test The following table contains important information on the type and scope of tests for ambient mechanical conditions. Table 1-6 Test ...…

establishes that the three sources of damage be added and that the resulting fatigue life be above 250 years. Most of the damage is due to VIV, followed by first order motions. The damage due to second order motions is negligible. vortex Induced vibrations (vIv) The VIV response of an FSHR generates fatigue damage that is low along the majority of the riser length, but high at the two ends of the vertical section of the system. The critical region for VIV damage tends to occur in…

number, the flow is turbulent; if it is lower than a critical Reynolds number, the flow is laminar. For flow in a pipe, assuming the typically rough pipe wall, the critical Reynolds number is usually taken to be 2000; if the wall is smooth and free of vibrations, and the entering flow is free of disturbances, the critical Reynolds number can be as high as 40 000. The critical Reynolds number is different for each geometry. For flow between parallel plates, it is taken as 1500 using the…

Nowadays, design measures have ensured that the advantages are not outweighed by the inevitable disadvantages on the front axle. These disadvantages are: • Less favourable kinematic characteristics (Sections 3.3 and 3.5.2). • Introduction of forces and vibrations into the inner wheel house panel and therefore into a relatively elastic area of the front end of the vehicle. • It is more difficult to insulate against road noise - an upper strut mount is necessary (Fig. 1.9), which should be…

contact your Shimadzu representative for installation, adjustment, or re-installation after moving the instrument to a different site. WARNING • Take measures to prevent the instrument from falling in the event of earthquake or other disaster. Strong vibrations could cause the instrument to fall over, resulting in injury. • The power supply voltages and power consumptions of this instrument are listed below. The power supply voltage of the instrument is indicated on the label on the…
