Vibration will be felt by all engineering structures, whether it be a machine, a spinning device such as a turbine, or civil infrastructures such as a building or a bridge. Read more about the importance of Vibration Structural Analysis. Machines, like humans, are subject to vibration which can be caused by unbalance in rotating devices, as well as vibratory loads from the ground and neighboring machines. It goes without saying that it is critical for almost all industrialists to understand vibration as well as to know how to solve vibration problems and come up with solutions that allow vibration to be controlled and minimized.

You may have encountered various issues related to vibration, and only a few people realize that, when it goes wrong, it goes wrong badly, so you may not specialize in them or be particularly interested in the dynamics, but what you should strive to do is recognize when there's a calibration problem so that you can seek expert advice. Structural Vibration analysis allows you to figure out how a structure reacts to vibration. Vibration Structural Analysis forecasts the dynamic impacts of the equipment itself, allowing for the avoidance of resonance. Unbalance, misalignment, pulsation forces, cross-head guide forces, cylinder gas forces, moments, and other forces are examples of dynamic loads.

Machine-related loads can create localized structural resonance because they occur across multiple frequency ranges. Structural resonance is a common source of vibration-related breakdowns in piping and mechanical systems in offshore manufacturing facilities.

Scope of Vibration Structural Analysis

The process of vibration structural analysis can be divided into three categories:

• Static analysis: Internal forces and displacements due to time-independent loading conditions are determined using static analysis.

• Stability analysis: This process is concerned with products that are subjected to time-independent forces that are compressed.

• Vibration analysis: The natural frequencies/eigenvalues and accompanying mode shapes (eigenfunctions) of vibration in a product are determined via vibration analysis.

The use of structural vibration monitoring to assess structural integrity is a low-cost option. Structural vibration happens when dynamic forces generated by pumps,  compressors, and engines result in the deck beams vibrating. Pipe breakdowns, poor equipment safety and reliability concerns are all caused by vibration. The structure is mechanically resonant, which causes the vibration. Resonance occurs when dynamic forces coincide with the inherent frequencies of the supporting structure. At resonance, the forces are multiplied by 20 times, forcing deck beams to shake beyond their safe operating limits.

High vibration might be experienced on offshore production platforms with reciprocating or spinning machinery. These high vibrations can lead to equipment failure, lost output, high maintenance costs, and environmental and human safety concerns. Structural vibration concerns can be reduced if they are adequately handled during the design phase.

Structural vibration reduction necessitates specific knowledge, methods, and design tools, as well as vast experience, all of which Technomax customers are entitled to.

Specialized vibration engineering service providers, such as Technomax, can accomplish what they do best because of the following:

• An accurate understanding of the dynamic forces generated by the machinery is required for the evaluation (frequency, amplitude, changes by operating condition, etc.). Pulsation research, mechanical analysis, and other non-structural engineering analyses are used to determine these forces.

• The dynamic FE model has numerous adjustments and changes. Field testing of platforms and FPSO modules with shaker test equipment, dynamic vibration studies, and other field measurements led to these adjustments. It is necessary to apply field results to dynamic FE models in order to obtain reliable findings. 

• We make sure our findings are reliable as the boundary condition assumptions must be correct. When two identical units on a platform are subjected to dynamic stress, they may perform very differently. This is due to the fact that the support structure's flexibility affects their dynamic behavior. The dynamic analyses of the skid and machinery are combined with the deck model to achieve appropriate boundary conditions by us.

• Technomax offers software and technology that can convert structural models into dynamic models, allowing for more efficient analysis.

• Technomax aims to provide a simplistic method of Vibration Structural analysis that can help reduce the whole maintenance cost in general. Our accurate and cost-effective method for new or existing offshore projects is based on multiple field experiences.
