Electric Vibration Test System: Introduction, Applications and Testing Standards
In the field of industrial testing, ensuring product reliability under dynamic environmental conditions is crucial for market competitiveness and safety compliance. As a leading manufacturer of testing equipment, Guangdong Jianqiao Testing Equipment Co., Ltd provides high-performance electric vibration test systems that simulate vibration environments encountered by products during transportation, operation, and storage. This blog will introduce the core principles, wide-ranging applications, and key testing standards of electric vibration test systems, helping you gain a comprehensive understanding of this essential testing equipment.
1. What is an Electric Vibration Test System?
An electric vibration test system is a precision testing device designed to simulate mechanical vibration environments, evaluate the structural integrity, performance stability, and durability of products. Unlike other vibration test equipment, it adopts an electric drive mode—with a linear motor as the core component—to generate controllable, high-precision vibration signals (including sine, random, shock, and combined vibration).
The core components of an electric vibration test system include: a vibration table (worktable), linear motor (drive source), power amplifier, vibration controller, and sensors (accelerometer, displacement sensor). The vibration controller sends control signals to the power amplifier, which amplifies the signals to drive the linear motor, making the table generate vibration with specified frequency, amplitude, and acceleration. Sensors collect real-time vibration data and feed it back to the controller for closed-loop adjustment, ensuring the accuracy and stability of the test process.
Compared with hydraulic vibration systems, electric vibration test systems have advantages such as high frequency range (usually 5Hz-2000Hz, even up to 10000Hz for high-frequency models), precise control, low noise, small footprint, and easy maintenance—making them the preferred choice for most industrial product vibration testing.
2. Key Applications of Electric Vibration Test Systems
Electric vibration test systems are widely used in various industries, covering automotive, electronics, aerospace, military, communication, medical equipment, and consumer goods. Their core function is to simulate the vibration environments that products may encounter in the whole life cycle, identify potential defects in design, material, and manufacturing, and improve product reliability. Typical application scenarios are as follows:
2.1 Electronics and Electrical Industry
This is the most common application field of electric vibration test systems. Electronic products (such as smartphones, computers, circuit boards, connectors, LEDs, and batteries) need to undergo vibration testing to ensure they can withstand vibration during transportation (e.g., truck transportation, air freight) and daily use (e.g., industrial equipment operation, home appliance vibration). For example, circuit boards are tested to avoid solder joint detachment or component damage; batteries are tested to prevent leakage, short circuit, or explosion caused by vibration.
2.2 Automotive Industry
Automotive parts (engines, transmissions, sensors, connectors, lights, seats, and electronic control units) must withstand severe vibration during vehicle operation (e.g., road bumps, engine vibration). Electric vibration test systems simulate different road conditions (urban roads, highways, off-road) to test the durability and reliability of automotive parts. In addition, new energy vehicle batteries and motor systems also require strict vibration testing to ensure driving safety.
2.3 Aerospace and Military Industry
Aerospace and military products (aircraft components, satellite parts, missiles, and military equipment) face extreme vibration environments during launch, flight, and landing. Electric vibration test systems simulate high-intensity vibration, shock, and random vibration environments to verify the structural strength and performance stability of these products—ensuring they can work normally in harsh conditions. This field has extremely high requirements for the precision and reliability of vibration test systems.
2.4 Other Industries
- Communication Industry: Test communication equipment (base stations, routers, antennas) to ensure they can withstand vibration in outdoor installation and transportation.
- Medical Equipment: Test medical devices (ultrasound machines, monitors, medical sensors) to ensure their accuracy and stability are not affected by vibration in hospital environments.
- Consumer Goods: Test daily necessities (home appliances, toys, furniture) to improve their durability and service life.
3. Main Testing Standards for Electric Vibration Test Systems
Vibration testing must comply with relevant national and international standards to ensure the authority, comparability, and validity of test results. Different industries and products have corresponding standards, and the common testing standards for electric vibration test systems are as follows:
3.1 International Standards
-
IEC (International Electrotechnical Commission): IEC 60068-2-6 (Environmental testing - Part 2-6: Tests - Test Fc: Vibration (sinusoidal)), which specifies the sinusoidal vibration test methods for electronic and electrical products, including test parameters, procedures, and evaluation criteria.
-
ISO (International Organization for Standardization): ISO 16750 (Environmental conditions and testing for electrical and electronic equipment for road vehicles), which specifies vibration test requirements for automotive electronic equipment, covering different vehicle types and usage environments.
-
MIL-STD (Military Standard): MIL-STD-810H (Environmental Engineering Considerations and Laboratory Tests), which includes strict vibration and shock test requirements for military equipment, simulating various harsh environmental conditions such as transportation, combat, and launch.
3.2 National Standards
-
GB/T (National Standard of China): GB/T 2423.10-2019 (Environmental testing - Part 2: Test methods - Test Fc: Vibration (sinusoidal)), equivalent to IEC 60068-2-6, applicable to electronic and electrical products in China.
-
GB/T 10175-2021 (Test methods for air conditioning and refrigeration equipment vibration), specifying vibration test methods for air conditioning and refrigeration equipment.
3.3 Industry-Specific Standards
In addition to general standards, many industries have their own specific vibration test standards. For example, the automotive industry has SAE J1455 (Environmental Conditions and Test Procedures for Electronic Equipment for Motor Vehicles); the aerospace industry has RTCA DO-160 (Environmental Conditions and Test Procedures for Airborne Equipment); the consumer electronics industry has Apple’s internal vibration test standards for iPhones and iPads.
