Six dimensional vibration table, suitable for testing scenarios with different load samples

working principle

This system is based on the principle of adaptive closed-loop control. The control software first obtains key information such as the mass, center of gravity, and moment of inertia of the current load (sample) through "model identification" or manual input. The controller then automatically adjusts the gain and compensator of the control algorithm based on these parameters, forming a control strategy for the current load. When driving the coordinated motion of six actuators, the system dynamically adjusts by continuously comparing the real-time feedback signal with the target signal, ensuring that the table can output accurate and stable six degrees of freedom motion regardless of light or heavy loads, effectively suppressing control instability or accuracy decline caused by load changes.

humidification system

To increase the humidity dimension for environmental simulation, its design also considers compatibility:

• Non invasive integration: Humidification systems are usually integrated into environmental chambers and do not interfere with the core mechanical structure of the vibration table, so no modifications are required when replacing loads or fixtures.

• Wide range control: Provides a relative humidity control range of 20% to 98%, which can meet the testing requirements of the vast majority of electronic products, materials, and products.

• Collaborative stress application: It can operate synchronously with vibration and temperature according to a preset profile, and apply comprehensive temperature humidity vibration stress to the load.

purpose

This device is widely used to evaluate the reliability of products of different weights and sizes in dynamic environments:

• Lightweight samples: Vibration resistance testing of smartphones, precision sensors, and communication modules.

• Medium sized samples: durability assessment of automotive controllers (ECUs), servers, and onboard navigation equipment.

• Heavy duty samples: ultimate load verification of electric vehicle battery packs, aircraft engine components, and satellite support structures.

Product performance

• Load compatibility: A system can cover the testing requirements of the vast majority of products through configuration adjustments, with strong universality.

• Excellent control stability: The intelligent adaptive algorithm ensures stable operation of the system under various working conditions such as no-load, unbalanced load, and full load.

• High precision and repeatability: No matter how the load changes, the system can ensure consistency of testing conditions and comparability of results.

• Quick setup and switching: User friendly software guidance and parameter preset functions greatly improve testing efficiency after sample replacement.

重要性

Strong load adaptability is crucial for modern laboratories and manufacturing enterprises. It means that there is no need to invest in multiple specialized equipment for products of different scales, significantly reducing procurement and maintenance costs. At the same time, it ensures the uniformity of testing standardization, avoids test data deviation caused by the use of different precision and equipment, provides a consistent and reliable benchmark for product design iteration and quality judgment, thereby accelerating the research and development process, improving product quality and market competitiveness.

meet the standard

Its extensive load adaptability and precise control capability enable it to meet numerous international and domestic testing standards, such as:

• IEC 60068-2-6/64: Environmental testing for electrical and electronic products - Vibration and random vibration.

• ISO 16750-3: Environmental conditions and tests for electrical and electronic equipment of road vehicles.

• MIL-STD-810G/H: Environmental Engineering Considerations and Laboratory Testing.
