Introduction
A vibration chamber is a test system used to test the products and the components under the controlled vibration, by the application of the vibration at the specified frequencies, the amplitudes, and the durations, and it is used in the electronics, the automotive, the aerospace, the defense, and the many other industries for the vibration testing and the reliability testing. The vibration chamber consists of a vibration shaker, which generates the vibration by the electromagnetic or the electrohydraulic drive, a test fixture or a table that holds the test article, a control system, and, in some models, an environmental chamber that provides the temperature and the humidity in combination with the vibration; the vibration chamber applies the vibration to the test article according to the test profile, such as the sinusoidal vibration, the random vibration, and the shock, and it is used for the testing of the vibration resistance of the products, for the testing of the transportation and the handling vibration, for the testing of the resonance, for the testing of the durability, for the qualification and the acceptance testing, and for many other applications, following the standard test methods, such as the IEC 60068 and the MIL-STD-810; the vibration chamber provides a controlled and a reproducible test, with features such as the programmable vibration profiles, the monitoring of the acceleration and the frequency, and the data logging, and it is available in various sizes and force capacities. Vibration chambers are used in the electronics industry, in the automotive industry, in the aerospace industry, in the defense industry, and for many other applications. With their vibration testing, vibration chambers are essential for the reliability testing.

FAQ
Q1: What testing scenarios is this chamber mainly applied to?
A: The vibration chamber (vibration shaker system) subjects products to controlled mechanical vibration or shock to evaluate durability, fatigue, and performance under transport/use conditions. Used for electronics (PCB/component solder joint reliability, hard drives, mobile devices, battery packs - resonance search, fatigue, random vibration per IEC 60068-2-6/64, JEDEC), automotive (components (sensors, ECUs, connectors) under road vibration (ISO 16750-3, LV 124), interior parts, battery modules), aerospace/defense (avionics, military equipment (MIL-STD-810G/H Method 514.6 vibration, 516.8 shock), spacecraft hardware), packaging (transport simulation (ASTM D4169, ISTA 1A/3A - vibration + drop + compression), and industrial products (appliances, tools, machinery durability). System components: shaker (electrodynamic (most common, wide freq 5-3000 Hz, high force) or mechanical/electro-hydraulic (low freq, high displacement)), power amplifier, vibration controller (sine, random, shock, SRS, sine-on-random), cooling (air/water), and fixture (adapts product to table - must be designed for test). Test types: sine (resonance search/dwell, fatigue), random (real-world simulation, PSD profile), shock (half-sine, trapezoidal, terminal peak sawtooth), combined (temperature + vibration with chamber on shaker).
Q2: What standards does the shaker comply with?
A: Complies with IEC 60068-2-6 (vibration, sinusoidal), IEC 60068-2-64 (vibration, random), IEC 60068-2-27 (shock), ISO 16750-3 (automotive environmental - vibration), MIL-STD-810G/H Method 514.6 (vibration), 516.8 (shock), ASTM D4169 (shipping containers), ISTA (transport simulation), JEDEC JESD22-B103/110/111 (semiconductor vibration/shock), and GB/T 2423. Hardware meets force rating (N/lbf), frequency range (5-3000 Hz typical), displacement (peak-to-peak mm), acceleration (g), and transverse motion (<25% per IEC). For ISO 17025 labs, calibrate shaker (accelerometer traceable, frequency response, amplitude accuracy) and maintain records. For automotive/aerospace, follow specific test profiles (PSD, sine sweep) from standards or customer specs. Fixture design critical: must be rigid (no resonance in test range), transmit vibration uniformly, and not add modes (verify with accelerometer survey).
Q3: What is the warranty period for the whole system and key components?
A: Whole system covered 12-24 months (specialized test equipment often 1-2 years). Shaker armature/coil (wear - can burnout from overstress/overcurrent; 5-10 years proper use), power amplifier (wear - 5-10 years, electronics), cooling fan/blower (wear - 3-7 years), accelerometers (wear - drift, 3-5 years; calibrate regularly), and controller (electronics 5-10 years) are key components. Damage from improper use, over-forcing (exceeding force/displacement/acceleration ratings - armature burnout, amplifier fault), improper fixture (heavy/unbalanced fixture causes side loads, armature wear), no cooling (overheating - armature burnout), dropping product on table (damage), or unauthorized repair (high-voltage amplifier - only qualified service) is excluded. Extended warranty and service contracts (preventive maintenance, calibration, armature rewind) common for high-use shakers. Armature 5-10 years (overstress kills); amplifier 5-10 years; accelerometers 3-5 years (calibrate). Consumables: accelerometers, cables, fixture materials.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained test engineers (familiar with vibration testing, standards, fixture design). Workflow: design/fabricate fixture (rigid, matches product mounting, verify no resonance in test range), mount product/fixture on shaker table (torque to spec, balance load - center of gravity over armature to minimize side load), attach control accelerometer (at product or fixture per standard - control point), connect amplifier and controller, program test profile (sine sweep (freq range, rate, amplitude), random (PSD profile, duration), shock (pulse shape, amplitude, duration), start test (ramp up, monitor response - product may have resonance; dwell at resonance if required), monitor (control acceleration, product performance (power on during test if required), check for loose parts), post-test (inspect product for damage, functional test, report). Training 2-5 days (controller programming, fixture design, safety, standards, troubleshooting). Safety: MOVING TABLE (shaker moves at high acceleration - keep hands away, use guards, emergency stop; product can come loose and become projectile - secure properly, use safety cage/screen), HIGH VOLTAGE (power amplifier outputs high voltage/current to shaker - do not touch armature/cables during operation, lockout/tagout for service), NOISE (shaker can be loud (>85 dB) - wear hearing protection, enclose if needed), COOLING (air-cooled shakers blow high-velocity air - keep objects away; water-cooled requires water supply), PRODUCT HAZARD (batteries on shaker can catch fire/explode if damaged - use fire extinguisher, containment; flammable products - assess risk), do not exceed ratings (force = mass x acceleration; heavier product = lower max acceleration; verify force margin), do not run without cooling (armature overheats), do not unbalance load (side loads damage armature/suspension - use guided head expander for large products), for combined temp-vibration: ensure chamber/shaker interface sealed, cables rated for temp, for shock testing: use shock amplifier or drop mechanism, verify pulse shape with accelerometer, for random vibration: RMS acceleration based on PSD; crest factor 3 typically; watch for peaks (3x RMS).
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibrate every 6-12 months: accelerometers (calibrate with reference accelerometer/shaker calibrator, traceable to national standards - frequency response, sensitivity), shaker amplitude (verify acceleration at multiple frequencies with calibrated accelerometer), frequency accuracy, and transverse motion. Routine: verify control accelerometer before each test (back-to-back calibration with reference), check cooling, inspect armature suspension. For ISO 17025, maintain calibration records (accelerometer IDs, as-found/as-left, frequency response, shaker mapping). Recalibrate after armature repair, amplifier service, relocation, or if readings drift. For critical aerospace/automotive testing, verify shaker performance (frequency response, transverse) annually. Accelerometers drift - calibrate every 12 months (or 6 months for high-use). Fixtures should be characterized (resonance survey) before use and periodically if modified.
Q7: Are supporting consumables universal?
A: Accelerometers (IEPE/charge, specific sensitivity - universal from PCB Piezotronics, Br
