Structural Vibration and Ways to Avoid It

2 Structural Vibration and Resonance. Structural vibration occurs when dynamic forces generated by compressors, pumps, and engines cause the deck beams to vibrate. This vibration leads to piping failures, poor equipment reliability, and safety concerns. The vibration is due to the structure being mechanically resonant.

 · as shown in figure 2, the inertial vibration exciter placed in the mass center of the screen produces a harmonic force, and its x directional and y directional forces, respectively, can be given as where,, and are the mass, eccentricity, and angular velocity of the eccentric block, respectively; and is the vibration direction angle (the angle .

Vibratory Feeder: What Is It? How Does It Work? Types Of

The guided movement produced by a vibratory feeder is dependent on horizontal and vertical accelerations that produce the exact amount of force needed to put materials in position. The accumulation track of a vibratory feeder, which can be linear or gravity, slows feeder vibrations and assists in directional movement.

FlowInduced Vibration (FIV) Analysis

Flowinduced vibration, or vortex shedding, is due to high flow velocities such as in a piping dead leg of a centrifugal compressor system. This study evaluates vortex shedding and potential vibration across dead leg branches. The study can also include FIV excitation of smallbore piping and components in the flow, such as thermowells.

Impact Force Calculator

First, we need to convert km/h to m/s, which gives us 27 / = m/s. Then we apply the first equation since we know the deformation distance, which is 75 cm = meters. Replacing in the formula we get F avg = · 2400 · 2 / = 90 kN and a maximum impact force of 180 kN. ( calculation link) Example 2: Using the situation in ...

Electrodynamic Shaker | Vibration Test System

When the required vibration signal is generated from the signal generator or vibration controller of the vibration test system and transmitted to the drive coil of the armature after being amplified by the power amplifier, the excitation force of the armature is generated when the corresponding alternating current passes through the drive coil.
