The importance of vibroacoustic analysis in the design phase

The vibroacoustic analysis of electric motors and electromechanical devices plays a key role in the final performance of the product.

Why vibroacoustic analysis is important?

• User comfort: users don’t want to experience unwanted vibrations and noise. This aspect is related both to comfort and safety at work. Just think of how much time the workers spend in front of a machine every day. Vibrations and their related noise affect the quality and hearing of the operator
• Components lifetime: vibrations can affect the lifetime and reliability of mechanical components. Let’s think for example of a household appliance or a drill, they are all work tools which by nature emit constant vibrations and therefore affect the mechanical part of the object itself
• Predictive maintenance and failure location: studying noise, vibrations and their sources in a machine can help identify its mechanical problems, even problems that are yet to arise in some cases
• Process analysis: keeping vibrations in check is very closely tied to the repeatability and reliability of the production process

There is  some simulation software on the market dedicated to vibro-acoustic analysis. Explore the vibroacoustic software from Altair

• Simsolid for fast analysis without mesh
• Hypermesh and Optistruct: dedicated to in-depth FEM analysis
• Activate and PSIM there software that simulate motor control and the effect on current, torque and torque ripple

These tools can be combined with other CAE software to evaluate vibrations during the design phase of the electric device/motor.

What companies recently ask us to do

• Analyze the device during the design phase
• Carry out vibro-acoustic tests on electric devices and motors in our laboratory

Spin is equipped with a laboratory for testing electric motors and electro-mechanical devices.
