Combined Environmental Chamber Humidity Control For Rail Vehicle Components

1. Product Name and Purpose

2. Product Features

Custom Vibration Shaker

• Precise and Tailored Vibration Generation
  • The custom vibration shaker is engineered to generate a wide spectrum of vibration frequencies, typically adjustable from 1 Hz to 2000 Hz. This broad range allows for the simulation of various types of vibrations that rail vehicle components experience. For example, low - frequency vibrations can mimic the rolling motion of the wheels on the tracks, while high - frequency vibrations can represent the vibrations caused by the operation of the traction motor or the impact of uneven tracks. The vibration amplitude is precisely controllable, with a range of 0.1 mm to 100 mm (peak - to - peak), enabling the reproduction of different levels of vibration intensity.
  • One of the key features of the custom vibration shaker is its ability to generate vibrations in multiple axes. Rail vehicle components are often subjected to complex multi - directional forces. The shaker can generate vibrations in vertical, horizontal, and sometimes rotational axes, providing a more realistic simulation of the actual mechanical stresses. This multi - axis functionality is crucial for detecting potential weaknesses in the component's structure and internal connections.
• Highly Customizable Vibration Profiles
  • Operators have the flexibility to create highly customized vibration profiles based on specific test requirements. These profiles can incorporate continuous vibrations, intermittent shocks, or complex sequences that mimic the exact vibration scenarios rail vehicle components are likely to face. For instance, a profile can be designed to simulate the vibrations during a long - distance high - speed train journey, including the vibrations during acceleration, deceleration, and traversing different track conditions. The ability to customize these profiles ensures that the testing is as realistic as possible, closely replicating the conditions in the rail environment.
• Robust and Durable Design
  • Built with high - quality materials and advanced engineering, the custom vibration shaker is designed to withstand the rigors of continuous testing. The shaker's frame is constructed from heavy - duty steel, providing a stable and rigid platform for generating vibrations. The vibration - generating mechanism is engineered for long - term reliability and precision, ensuring consistent and accurate test results over extended periods. Additionally, the shaker is designed to handle a wide range of payloads, from small components like sensors to large and heavy parts such as bogie assemblies.

Temperature Humidity Test Chamber

• Comprehensive Environmental Simulation
  • The temperature humidity test chamber integrated with the vibration shaker can create a wide range of environmental conditions. The temperature can be adjusted from extremely low values, such as - 40°C to simulate cold climate regions, to high temperatures of up to + 80°C to mimic hot and humid climates. The humidity control can maintain relative humidity levels from 10% to 95%, enabling the testing of how components respond to different moisture levels. This is crucial as high humidity can cause corrosion, electrical short - circuits, and other malfunctions in electronic components, while low humidity can lead to issues such as static electricity build - up.
  • The chamber can also simulate rapid temperature and humidity transitions. Rail vehicles may experience sudden changes in the environment, such as moving from an air - conditioned station to a hot outdoor track or vice versa. The chamber can achieve temperature transition rates of up to 5°C/min and humidity transition rates of up to 5%/min, allowing for the testing of how components respond to these abrupt changes.
• Large and Uniform Test Volume
  • The temperature humidity test chamber features a large test volume, typically ranging from 5 m³ to 50 m³, depending on the model. This spacious interior can accommodate a variety of rail vehicle components, from individual parts to complete sub - assemblies. The chamber is designed to provide uniform temperature and humidity conditions throughout the test volume, with temperature variations within ±1°C and humidity variations within ±5% relative humidity. This ensures that all parts of the tested components 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 vibration shaker and the temperature humidity test chamber. It provides a clear display of the current test status, including vibration frequencies, amplitudes, 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 component 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 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 particularly valuable in the rail industry, where testing may need to be conducted in large manufacturing facilities or maintenance depots. 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.
