Vibration - Modal - Acoustic Analysis

Modal Analysis is an engineering process of reviewing dynamic and vibration characteristics of a machine part, component or product. A thorough simulation helps manufacturers understand and resolve unwanted vibration patterns regarding resonant frequencies and damping values. If unwanted acoustic noise in your structure is your problem, then FEA outsourcing´s modal analysis services is the optimum solution for you.

We use CAD simulations to predict the shapes and frequencies of the vibrations by first determining the natural frequency of the material and then looking into forced and resonance frequencies.

Our services allow us to deliver following results:

  • Eradication of Unnecessary vibration and noise
  • Resolve resonance problems
  • Provide design verification
  • Overall process improvement
  • Condition monitoring and troubleshooting

In order to understand the behaviour of any component, it is extremely important to precisely simulate the mode shapes (eigenvectors), along with the component´s stiffness, mass distribution, and damping. We would help in determining noise sources from different places of the machinery or component such as joints, rotating parts, foundation etc.

The frequency responses from the modal analysis help in determining any kind of threat to the component from such vibrations. For e.g. if the frequency is near to the resonance frequency of the component, then they can cause serious damage to the product. In case, the matter is not solved, other simulations are performed until the the levels reach permissible limits.

We have wide experience with analysis of large and complex machinery and components across several industries. Our team of experts have in-depth knowledge and experience in frequency testing systems such as Bruel and Kjaer, Prosig, and Agilent. Our services also include noise testing and analysis with thermo-structural FEA.
