1. Product Name and Purpose

2. Product Features

Random Vibration Test Machine

• Realistic Random Vibration Simulation
  • The random vibration test machine is engineered to generate a broad - spectrum random vibration profile, typically spanning a frequency range from 2 Hz to 2000 Hz. This wide range is essential as it can accurately replicate the complex and erratic vibration patterns that industrial control equipment is exposed to in actual industrial environments. The machine precisely controls the vibration power spectral density (PSD), enabling the precise reproduction of different levels of random vibration intensity.
  • The random vibration generation is based on state - of - the - art algorithms and control systems. These ensure that the vibration profile closely mimics the real - world vibrations, which may stem from multiple sources such as rotating machinery, reciprocating engines, and vibrating conveyors. This realistic simulation is crucial for identifying potential weaknesses in the equipment's structure, internal components, and connections that could be affected by these complex vibration inputs.
• Multi - Axis Vibration Capability
  • It has the ability to generate vibrations in multiple axes, usually three - axis (X, Y, and Z), providing a more realistic representation of the mechanical stresses experienced by industrial control equipment. In industrial settings, equipment often endures vibrations in different directions simultaneously. For instance, a DCS cabinet mounted on a factory floor may experience vertical vibrations from the floor's movement, horizontal vibrations from nearby machinery, and lateral vibrations during equipment installation or maintenance. The multi - axis vibration capability of the test machine helps to uncover potential weaknesses in the equipment's design that may be overlooked with single - axis testing.
• Customizable Test Profiles
  • Operators enjoy the flexibility to create highly customizable random vibration test profiles. They can define parameters such as the test duration, frequency range, and PSD levels to align with the specific vibration conditions of different industrial applications. For example, a test profile can be tailored to simulate the vibrations in a textile mill, where the equipment is exposed to relatively low - intensity but continuous vibrations, or in a mining operation, where the equipment is subjected to high - intensity and intermittent vibrations.

Climatic Test Chamber

• Broad Climatic Range
  • The climatic test chamber integrated with the random vibration test machine can create an extensive range of climatic conditions. The temperature can be adjusted from extremely low values, such as - 40°C to simulate cold storage facilities or outdoor winter operations, to high temperatures of up to + 85°C to mimic hot industrial environments like steel foundries or chemical plants. The humidity control can maintain relative humidity levels from 10% to 95%, enabling the testing of how industrial control equipment responds to different moisture levels.
  • Additionally, the chamber can simulate other climatic factors such as condensation, icing, and dust exposure. Condensation and icing can pose significant challenges to industrial control equipment, especially in applications where the equipment is exposed to rapid temperature changes or high humidity. Dust exposure is also a common issue in industrial settings, and the chamber can simulate different levels of dust concentration to test the equipment's resistance to dust ingress.
• Fast Climatic Transitions
  • Industrial control equipment may encounter sudden changes in the climate, such as when moving from a cool, air - conditioned control room to a hot, humid production area. The climatic test chamber is capable of rapid climatic 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 equipment responds to these abrupt changes, which can cause thermal stress, moisture - related issues, and potential component failures.
• Uniform Climatic Conditions
  • The interior of the climatic test chamber is designed to provide uniform climatic 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 industrial control equipment 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 climatic test 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 any observed equipment failures or performance changes. 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, technicians, and quality control personnel 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 highly valuable in industrial settings, where testing may need to be conducted in large factories, remote locations, or hazardous environments. Operators can monitor the test progress and adjust the test parameters from a remote location, such as an office, a control center, or even a mobile device. This allows for continuous supervision and timely intervention, ensuring the efficiency and effectiveness of the testing process.
