1. Product Name and Purpose

2. Product Features

Random Vibration Test Machine

• Realistic Random Vibration Simulation
  • The random vibration test machine is capable of generating a wide - spectrum random vibration profile, typically covering a frequency range from 2 Hz to 2000 Hz. This broad range enables the replication of the complex and unpredictable vibration patterns that sensors and instruments are likely to encounter in real - world applications. The machine can precisely control the vibration power spectral density (PSD), allowing for the accurate reproduction of different levels of random vibration intensity.
  • The random vibration generation is based on sophisticated algorithms that mimic the actual vibration sources in various industries. For example, in the automotive industry, sensors may experience vibrations from the engine, suspension, and road irregularities. The test machine can generate vibration profiles that closely resemble these real - world vibrations, helping manufacturers to identify potential issues related to component failures, signal interference, or inaccurate measurements caused by vibrations.
• Multi - Axis Vibration Capability
  • It can generate vibrations in multiple axes, usually three - axis (X, Y, and Z), which is essential for sensors and instruments as they often experience vibrations from different directions simultaneously. In an aircraft, for instance, sensors may be subjected to vibrations in all three axes during flight due to engine vibrations, air turbulence, and the movement of the aircraft's structure. The multi - axis vibration capability of the test machine allows for a more realistic simulation of these complex mechanical stresses, enabling manufacturers to test the performance of sensors and instruments under more representative conditions.
• Customizable Test Profiles
  • Operators have the flexibility to create highly customizable random vibration test profiles. They can define parameters such as the test duration, frequency bands, and PSD levels to match the specific vibration conditions of different applications. For example, a test profile can be designed to simulate the vibrations experienced by a sensor during a long - distance truck transportation, which may involve a combination of low - frequency vibrations from the vehicle's movement and high - frequency vibrations from road bumps.

Humidity and Temperature Chamber

• Wide Humidity and Temperature Range
  • The humidity and temperature chamber integrated with the random vibration test machine can create a broad range of environmental conditions. The temperature can be adjusted from extremely low values, such as - 40°C to simulate cold storage or arctic conditions, to high temperatures of up to + 85°C to mimic hot industrial environments or tropical climates. The humidity control can maintain relative humidity levels from 10% to 95%, enabling the testing of how sensors and instruments respond to different moisture levels.
  • This wide range of conditions is crucial as sensors and instruments are used in a variety of applications with different environmental requirements. For example, humidity sensors need to be tested under a wide range of humidity levels to ensure their accuracy, and temperature - sensitive instruments must be able to function properly in both cold and hot environments.
• Fast Transitions
  • Sensors and instruments may experience rapid changes in temperature and humidity in real - world scenarios. The chamber is capable of rapid transitions, with temperature transition rates of up to 10°C/min and humidity transition rates of up to 5%/min. This allows for the testing of how the devices respond to sudden environmental changes, which can be a significant stress factor for their performance and reliability. For example, a sensor in a manufacturing process may experience a sudden change in temperature and humidity when a new batch of materials is introduced.
• Uniform Environmental Conditions
  • The interior of the humidity and temperature chamber is designed to provide uniform environmental conditions throughout the test volume. The temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity. This ensures that all parts of the sensors and instruments being tested are exposed to the same environmental conditions, resulting in reliable and consistent test results.

Integrated Control and Monitoring

• User - Friendly Interface
  • The entire test system is controlled through a user - friendly interface that simplifies the operation process. The interface allows operators to easily set and adjust the test parameters for both the random vibration test machine and the humidity and temperature chamber. It provides a clear display of the current test status, including vibration frequencies, PSD levels, temperature, humidity, and elapsed test time. The interface is designed to be intuitive, even for users with limited technical expertise, ensuring efficient and accurate testing.
• Comprehensive Data Acquisition and Analysis
  • Equipped with a comprehensive data acquisition system, the test system records all relevant data during the test. This includes vibration measurements in multiple axes, temperature and humidity profiles, and the performance data of the sensors and instruments, such as measurement accuracy, response time, and signal stability. The data can be stored in a secure database and analyzed using advanced software tools. The system can generate detailed test reports, including graphs, charts, and statistical analysis, to help engineers and researchers understand the test results and make informed decisions.
• Remote Monitoring and Control
  • Many models of this combined test system offer remote monitoring and control capabilities. This feature is particularly useful for manufacturers who need to conduct tests in large facilities or in remote locations. Operators can monitor the test progress and adjust the test parameters from a remote location, such as an office or a control center. This allows for continuous supervision and timely intervention, ensuring the efficiency and effectiveness of the testing process.
