Hydraulic Vibration Exciters for Powerful Structural Simulation

Engineered for high-force, low-frequency vibration testing across civil, aerospace, and industrial applications

Overview

Acoustic excitation systems deliver non-contact methods for introducing controlled vibration energy into structures and components. Using sound waves or air-coupled pressure waves, these systems excite test subjects for dynamic analysis without physically touching or altering them. This approach is ideal for lightweight, sensitive, or irregularly shaped parts, especially in aerospace, electronics, and material research applications.

This page highlights how Vibration Dynamics Tech integrates acoustic excitation tools into testing environments for clients across North America. From flexible frequency control to real-time compatibility with modal analysis software, our systems enable engineers to perform reliable, accurate vibration testing for R&D, quality assurance, and performance validation. As a growing B2B provider, we deliver high-performance, innovative, and scalable testing solutions designed for evolving industry demands.

Case Studies

U.S. Case Study – Modal Testing of Satellite Panels

A U.S.-based aerospace contractor used our acoustic excitation systems to perform non-contact modal testing on lightweight satellite enclosures. The system helped verify the vibrational behaviour of panels under launch-like conditions without adding mass or altering surface conditions.

U.S. Case Study – Acoustic Excitation in Microelectronics QA

An electronics manufacturer deployed our portable acoustic system to detect resonance issues in sensor housings for wearable devices. Non-contact excitation allowed precise, repeatable testing without damaging sensitive components.

Canadian Case Study – Composite Materials Research

A Canadian university’s mechanical engineering lab integrated our system for acoustic excitation of new composite structures. This allowed researchers to identify modal frequencies and material damping behaviour in prototype bridge deck materials.
