Combined Temperature-Humidity-Vibration Test System – Custom Quotation Model

Overview

The Combined Temperature-Humidity-Vibration Test System is an integrated environmental reliability test platform engineered for simultaneous exposure of test specimens to controlled thermal, hygric, and dynamic mechanical stress conditions. It combines a high-performance electrodynamic shaker with a precision-engineered climatic chamber—capable of independent or synchronized operation—to replicate real-world service environments encountered by aerospace components, automotive electronics, defense systems, and industrial control units. The system operates on the principle of electromagnetic force generation via dual-magnetic-circuit actuation, delivering high-fidelity acceleration waveforms across a broad frequency spectrum (5–3000 Hz). Its core architecture supports rigorous qualification testing per MIL-STD-810, RTCA DO-160, and IEC 60068-2 series standards, enabling deterministic sinusoidal, random, shock (half-sine, terminal-peak sawtooth), and swept-sine vibration profiles while maintaining stable temperature (−70 °C to +180 °C) and humidity (10–98% RH) control.

Key Features

• Dual-Magnetic-Circuit Shaker Design: Minimized magnetic flux leakage and compact structural footprint ensure high power density and thermal stability during extended duty cycles.
• Advanced Motion Support System: Rocker-arm guidance combined with axial air-spring suspension delivers exceptional lateral load resistance and waveform fidelity—even at full rated payload (300 kg) and maximum displacement (51 mm p-p).
• High-Integrity Voice Coil Assembly: Precision-wound copper coils using aerospace-grade insulation materials and optimized thermal management provide long-term operational reliability under high-acceleration regimes.
• Center-Load Air Bearing Structure: Patented pneumatic centering mechanism enhances low-frequency response (<10 Hz) and improves load distribution uniformity across the shaker table surface.
• Bi-Axial Rotational Mounting Frame: Ear-mounted gimbal structure enables rapid 90° vertical/horizontal orientation switching without realignment; integrated isolation springs and linear guides suppress cross-axis coupling and external floor-borne interference.
• Modular Table Extension & Fixture Interface: Supports standardized auxiliary tables and custom-engineered fixtures compliant with amplitude uniformity (±1.5 dB), transverse motion (<15% axial), and modal neutrality requirements per ISO 10816-3 and ASTM E1492.

Sample Compatibility & Compliance

This system accommodates test articles up to 300 kg mass and dimensions compatible with standard 600 × 600 mm shaker tables (expandable via bolted auxiliary platforms). It meets all mechanical and environmental interface requirements defined in GB/T 2423.10-2008 (vibration), GB/T 13310-2007 (electrodynamic shaker performance), and GJB 360A-1996 (Method 204: sinusoidal; Method 213: classical shock; Method 214: random vibration). Full compliance includes IEC 60068-2-6 (vibration), IEC 60068-2-30 (damp heat cyclic), and IEC 60068-2-14 (temperature cycling). All control algorithms and data acquisition pathways are architected to support GLP/GMP audit readiness, including time-stamped event logging, user-access-level permissions, and electronic signature capability aligned with FDA 21 CFR Part 11 principles.

Software & Data Management

The system integrates with industry-standard real-time control software supporting closed-loop feedback compensation, multi-axis synchronization, and spectral shaping for random vibration synthesis. Data acquisition operates at ≥100 kS/s per channel with 24-bit resolution and anti-alias filtering. Export formats include UFF58, MATLAB (.mat), CSV, and ASAM MDF4—ensuring seamless interoperability with FEA validation workflows and enterprise LIMS platforms. Built-in diagnostic tools monitor coil temperature, amplifier output, chamber dew point deviation, and shaker armature centering status—generating automated health reports compliant with ISO/IEC 17025 calibration traceability frameworks.

Applications
