Electromagnetic Vibration Test Bench

Electromagnetic Vibration Test Bench Solutions for Testing Labs

This range covers bench‑top to high‑force systems for sine, random, shock, and resonance dwell testing. It supports plastics and rubber, electronics, automotive, aerospace, packaging, and wire & cable programs.

What Sets Our Benches Apart

Engineered and built in‑house under ISO 9001, the systems pair rigid mechanics with closed‑loop digital control for repeatable, traceable results. Extensive CNC machining, utility model patents, and work on national standards support compliance‑ready designs. We provide global installation, onsite commissioning, and lifetime service. Customization includes fixturing, controller options, and armature sizes to fit your payload and lab space.

Test Methods and Standards

Systems execute sine sweep, random PSD, classical shock, resonance dwell, and mixed‑mode tests with high fidelity. Preconfigured templates cover IEC 60068‑2‑6/64, ISO 16750, MIL‑STD‑810 Method 514, and ASTM D4169. Advanced options include user‑defined PSDs, SRS, and time history replication for reliability and transport simulations.

Configurations

Choose vertical‑only benches for compact payloads. Add a precision slip table for vertical and horizontal orientations. An XYZ three‑axis configuration enables simultaneous tri‑axial excitation. Air‑cooled models simplify installation; water‑cooled units support heavier payloads and long duty cycles. Head expanders and fixtures help maintain uniform acceleration on larger DUTs.

Core Technology and Safety

High‑energy electrodynamic drives deliver wide bandwidth with low distortion. Digital controllers use multi‑channel accelerometer feedback for closed‑loop control, auto‑tuning, notching, and real‑time spectrum monitoring. Rigid armatures, low‑friction guidance, and optimized suspensions limit cross‑axis motion. Overtravel protection, thermal monitoring, safety interlocks, and emergency stop circuits protect the operator and equipment.

Environmental Chamber Integration

Benches interface with constant temperature and humidity chambers for combined environment tests. Control and logging synchronize temperature, humidity, and excitation responses for full reliability assessment. All models share a unified control platform and are pre‑validated for fast chamber integration.

Selection Guide and Key Parameters

• Bench‑top series (to 5 kN): compact, air‑cooled; ideal for small electronics and R&D screening.


• Mid‑range (5–30 kN): balanced stroke and payload; available with horizontal slip table kits.


• High‑force (30–100 kN+): water‑cooled for large assemblies, battery packs, and extended random duty.

Typical parameters

• Frequency range: 2–3,000 Hz (higher with high‑frequency kits).


• Peak acceleration: up to 100 g, subject to payload and fixture mass.


• Displacement: up to 51 mm pk‑pk.


• Armature diameter: ~120–440 mm+.

Provide DUT plus fixture mass to select force rating and cooling method.

Applications

• Automotive and transport: brackets, ECUs, battery modules, harnesses under ISO 16750 road spectra with notching.


• Electronics and devices: PCBs and assemblies for resonance and solder fatigue; bench‑top units suit limited space.


• Aerospace and defense: MIL‑STD‑810 vibration, sine‑on‑random, and classical shock with multi‑channel control.


• Packaging: transportation profiles and ASTM D4169 to evaluate cartons and cushioning; combine with drop and compression tests.

Options and Software

Custom fixtures, lightweight head expanders, and granite or aluminum slip tables streamline setups. Controller tiers support sine, random, shock, time history replication, SRS, and multi‑axis coordination. Data export, limit profiles, and automated reporting aid qualification.

Installation, Calibration, and Support

We advise on foundation, isolation, power, and cooling. Commissioning verifies performance to specification with acceptance tests. Training, preventive maintenance, remote diagnostics, and in‑house calibration provide traceable documentation aligned with international standards.

Frequently Asked Questions

• Q: Can I use my existing controller and sensors?
  A: Controllers are selectable, and systems support common accelerometers. We verify compatibility during specification.


• Q: How should I design fixtures?
  A: Keep fixtures lightweight and stiff. Match the mounting pattern to the armature or head expander and avoid resonance in the test band.


• Q: Where should accelerometers be placed?
  A: Place control sensors near the DUT’s mounting points. Use additional response channels at critical locations.


• Q: What is profile notching?
  A: Notching reduces excitation at sensitive resonances to protect the DUT while meeting overall test objectives.


• Q: How do I add horizontal testing?
  A: Select a slip table package sized to your payload and frequency range. We supply guidance on alignment and lubrication.
