Services > Structural Dynamics

Structural dynamics involves many activities from study to on-site testing.

The performance of buildings of complex or unusual design for human occupation or special production processes must be considered in a number of ways. Machines must be supported on foundations of one type or another and, inevitably, there will be vibratory motion. There are limits to desirable or allowable vibration in all occupation and constructed situations. Computer models can be built and subjected to forces or motions so that performance may be predicted, or as an aid to solving problems.

NVM offers study/design and testing services including;

• Finite element modelling of structures and components (FEM using the Nastran computer program for example)
• Structural dynamics testing (using force hammer, of un-balanced mass shaker machine)
• Modal surveys and analyses
• Resonance avoidance, vibration or auxiliary mass damper design, etc.
• Seismic aspects for foundations, machines, buildings, etc.
• Foundations for machines (reciprocating compressors, engines, turbines, etc.)
• Building floor performance due to human inputs of walking, exercise, machinery inputs etc.
• Petro-chem structures, vessels, piping, etc.
• Trouble shooting where there are problems, solutions developed.
