Vibration Analysis Simulations

Why do We Need Vibration Analysis?

Vibration analysis allows users to mitigate the risk of physical vibration test failure. Many products are required to undergo physical vibration testing to be certified for safe usage under international standardization body regulations.

Using SimScale’s vibration analysis tools, you can:

• Lower your testing costs: One failed test likely costs more than a SimScale license.
• Mitigate test failure: Understand design weak points, iterate virtually, and optimize your design to increase survivability.
• Gain deeper insights: Unlike the pass-or-fail approach of physical testing, simulation helps you uncover the root causes of failure.
• Speed up time to market: Reduce time wastage associated with physical prototyping and testing failures.
• Go into physical testing with increased confidence: Use frequency analysis to define a physical test range with no risk of resonance.

A Look Into Frequency Analysis (Modal Analysis)

Modal analysis describes the limits of a system’s response to an applied load with a corresponding magnitude and frequency. By studying the system’s vibration response, engineers and designers can define particular design changes and approaches that maintain the system’s robustness and avoid issues of resonance.

With SimScale’s frequency analysis, users can evaluate the overall rigidity of their design structure and the local rigidity in particular regions by analyzing the natural frequencies of their structure. It can help determine the structure’s eigenfrequencies (eigenvalues) and eigenmodes (mode shapes) due to vibration.
