What Is Shock Isolation and How Does It Work?
Shock isolation involves absorbing the energy of the high amplitude, short duration impulse and re-distributing it over longer durations at lower amplitudes, reducing the risk to humans, equipment or even structures. It’s critical to remember that energy is never eliminated, only re-distributed.
Shock isolation systems rely on two principal characteristics to ensure minimum transmissibility — damping and deflection capacity. Damping dissipates some energy into heat, while maximizing deflection capacity as much as is practical allows for the lowest acceleration and longest duration response amplitudes. The process consists of three elements:
Deflect: The shock isolator responds to the shock by deflecting an amount that is defined by the shock event, the isolator’s elasticity and the inertial properties of the equipment the isolators are supporting.
Discharge: Once the impact is stored, the shock isolating system can discharge it at a frequency and amplitude dependent on the overall system properties.
Damping: Throughout the entire event, some energy is converted from mechanical energy to heat energy, typically through some frictional method.
Each shock pulse shape is different, defining the intensity of the shock and influencing the shock isolation system’s response. An appropriate shock isolation system takes into account the unique aspects of that shock impulse of concern in order to provide the most effective solution. During the selection of a cable isolator system, the cable diameter, the number of loops and the overall dimensions of the isolator can be fine-turned to provide an optimal response.
Shock isolation aims to ensure the shock output is significantly lower than the input by storing the energy from the initial impact.
SHOCK AND VIBRATION REDUCTION FOR THE OIL AND GAS INDUSTRY
Generators, compressors and mud pumps impose vibrational forces on oil rigs, causing structural fatigue. Vibrations sometimes occur in piping at such a high frequency they cause cracks while damaging essential components like supports and clamps.
Mitigating shock and vibration is a high priority for oil and gas operations. Besides causing expensive damage to valuable equipment, these hazards pose threats to a company’s workforce by potentially resulting in dangerous leaks.
