Overview
The OK-1000.1115 Electromagnetic Transport Simulation Vibration Shaker System is a high-fidelity, digitally controlled laboratory-grade shaker engineered for rigorous physical validation of product and packaging integrity under simulated multimodal transport conditions—including road, rail, sea, and air freight environments. Unlike basic sinusoidal exciters, this system implements closed-loop electromagnetic actuation based on Lorentz force principles, enabling precise reproduction of real-world vibration spectra defined in international logistics standards. Its design prioritizes metrological traceability, mechanical robustness, and deterministic control fidelity—making it suitable for reliability engineering, quality assurance (QA), and regulatory-compliant validation workflows in electronics, pharmaceutical packaging, automotive components, and consumer goods industries.
Key Features
- Electromagnetic drive architecture with high-strength neodymium permanent magnet circuit and low-inertia moving coil for linear force generation across 5–5000 Hz.
- Closed-loop acceleration control using integrated IEPE accelerometers and real-time feedback compensation to maintain RMS and peak spectral accuracy within ±1.5 dB tolerance.
- Digital vibration controller with 10.1-inch capacitive touchscreen interface supporting four primary test modes: fixed-frequency sine, swept-sine (logarithmic or linear), random vibration (PSD-based), and classical shock waveform replication.
- Built-in compliance library with preloaded test profiles conforming to ASTM D999, ISTA 2A/3A/3E, GB/T 4857.7–2021, ISO 2247, and MIL-STD-810H Method 514.8.
- Structural platform constructed from aerospace-grade aluminum alloy (6061-T6) with standardized 12.5 mm pitch threaded hole array (M6/M8) for repeatable fixture mounting.
- Integrated safety subsystem including dual-channel emergency stop circuitry, interlocked safety door switch, mechanical displacement limiters, and thermal monitoring for amplifier and voice coil.
- Modular cooling architecture: forced-air cooling standard; optional liquid-cooling upgrade available for extended high-g random testing.
Sample Compatibility & Compliance
The OK-1000.1115 accommodates test specimens up to 70 kg with center-of-gravity alignment within ±25 mm of the table’s geometric center. It supports rigid and semi-rigid packages, assembled electronic enclosures, medical device cartons, and palletized loads via custom fixtures or auxiliary top plates. All system-level calibration procedures follow ISO 16063-21 (vibration sensor calibration) and ISO 10816-1 (mechanical vibration evaluation). Test reports generated include timestamped time-history data, PSD plots, kurtosis/skewness metrics, and pass/fail annotations aligned with selected standard clauses—enabling full audit readiness for GLP, GMP, and FDA 21 CFR Part 11 environments when paired with validated software configuration.
Software & Data Management
The embedded controller firmware supports native export of raw acceleration time-series (CSV), PSD matrices (ASCII), and metadata-rich XML test logs. Optional PC-based analysis suite provides FFT spectrum overlay, transmissibility calculation, fatigue damage estimation (via Steinberg or Dirlik methods), and automated report generation compliant with ISTA documentation templates. Data integrity is ensured through SHA-256 hash logging, user-access role management (admin/operator/viewer), and electronic signature capability. Firmware updates are delivered via secure HTTPS channel with version rollback support and change-log documentation per IEC 62304 Class B requirements.
Applications
- Pre-shipment qualification of e-commerce packaging per ISTA 3A protocols.
- Resonance screening and modal analysis of automotive ECUs during design verification.
- Validation of sterile barrier integrity for Class II medical devices under simulated air cargo turbulence (ISO 11607-2 Annex C).
- Accelerated life testing of lithium-ion battery modules subjected to road-induced broadband excitation.
- Comparative assessment of cushioning material performance across varying PSD input spectra.
- Root cause analysis of solder joint fractures in PCB assemblies exposed to harmonic sweep profiles.
FAQ
What standards does the OK-1000.1115 natively support?
It includes built-in test programs for ASTM D999, ISTA 2A/3A/3E/6-FedEx, GB/T 4857.7–2021, ISO 2247, and MIL-STD-810H Method 514.8. Custom profiles can be imported via CSV or SDF format.
Is third-party calibration certification available?
Yes—factory calibration is traceable to NIM (China National Institute of Metrology); optional UKAS-accredited calibration certificates are available upon request.
Can the system perform multi-axis vibration simulation?
The OK-1000.1115 is a single-axis (vertical Z-axis) shaker. For triaxial testing, OK Instruments offers synchronized multi-shaker systems with phase-coherent control architecture.
What maintenance intervals are recommended?
Biannual inspection of air suspension preload, annual recalibration of accelerometers and force sensors, and quarterly verification of thermal protection thresholds per manufacturer’s maintenance logbook.
Does the controller support remote operation and monitoring?
Yes—the controller features Ethernet port with Modbus TCP and RESTful API interfaces for integration into factory MES or LIMS platforms; remote desktop access requires customer-provided secure VPN infrastructure.
