The Vibration Test System is to simulate real-world vibration environments, verifying the reliability and durability of products. Its structure is modular, functions are scenario-specific, and advantages lie in high simulation accuracy and risk prevention.

1. System Structure (4 Core Modules)

• Vibration Excitation Module: The "power source" of vibration, mainly including vibration exciters (electrodynamic, , piezoelectric types) and fixtures. It converts electrical energy into mechanical vibration and transmits it to the tested product via fixtures.
• Control & Measurement Module: The "brain" of the system, consisting of a vibration controller, sensors (accelerometers, displacement sensors), and data acquisition cards. It issues control signals, collects real-time vibration data (acceleration, frequency, displacement), and feeds back to adjust the excitation module.
• Auxiliary Support Module: Ensures stable operation, including cooling systems (for exciters), power supplies (stable voltage output), and safety protection devices (overload, over-temperature alarms).
• Software Module: Runs on the controller or upper computer, providing functions such as test parameter setting (frequency range, vibration waveform), data analysis (spectrum analysis, fatigue life calculation), and test report generation.

2. Core Functions

1. Vibration Environment Simulation: Reproduces specific vibration conditions, such as sinusoidal vibration (for rotating machinery like motors), random vibration (for vehicles, aerospace), and shock vibration (for product transportation, drop impacts).
2. Product Reliability Testing: Detects potential defects in products, such as loose components, cracked structures, or reduced performance, under long-term or extreme vibration conditions.
3. Performance Calibration: Calibrates vibration-sensitive devices (e.g., sensors, inertial navigation systems) to ensure their measurement accuracy in actual vibration environments.
4. Fatigue Life Prediction: Analyzes the cumulative damage of materials or structures under cyclic vibration, predicting their service life to guide product design optimization.

3. Key Advantages

• High Simulation Accuracy: Precisely controls vibration parameters (frequency error ≤0.1%, acceleration deviation ≤5%), ensuring consistency between test environments and real scenarios.
• Controllable & Repeatable: Test conditions can be standardized and repeated, avoiding the randomness of on-site testing and facilitating comparison of product performance before and after optimization.
• Risk & Cost Reduction: Discovers product failures in the laboratory stage, avoiding safety accidents (e.g., equipment damage, personal injury) and after-sales costs caused by unqualified products entering the market.
• Wide Applicability: Suitable for industries such as automotive (engine vibration), aerospace (satellite launch vibration), electronics (phone drop tests), and machinery (gearbox durability), with adjustable test ranges (frequency: 0.1Hz–10kHz, acceleration: 0–1000m/s²).

The Dual Vibration Test System operates in conjunction with an altitude simulation chamber, enabling testing of large payloads under near-vacuum conditions.

• Precision balancing control system maintains armature position
• Sealed floor connection ensures consistent vacuum conditions
• Multiple Amplifier Control (MAC) enables dual configuration operation
