Why Measure Sound & Vibration?
- R&D: Enhance product design by reducing noise and vibration, leading to longer service life and greater user appeal in appliances, vehicles, and tools.
- Structural Testing: Assess the integrity, material properties, and mode shapes of structures through vibration response analysis, identifying potential issues like fatigue or cracking.
- Control: Implement systems that detect and respond to noise or vibration changes, such as active suspension systems, cabin noise suppression, and vibration shaker control.
- Machinery Protection: Monitor vibration levels and automatically trigger alarms or shutdowns when thresholds are exceeded, preventing damage.
- Predictive Maintenance: Analyze machinery performance trends to schedule maintenance proactively and avoid catastrophic failures.
Sound and Vibration Measurement System Components
A Sound and Vibration Measurement System is typically divided into three main parts:
- Sensors: Capture input signals.
- Data Acquisition: Condition and convert signals (A/D, D/A, DIO, TIO).
- Analysis: Process and interpret the acquired data.
