Custom Vibration Shaker Climate Chamber For Rail Transit Communication Signal Equipment

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 transit communication signal equipment may experience. Low - frequency vibrations can mimic the steady - state vibrations during normal train operation, while high - frequency vibrations can represent the sudden impacts or vibrations caused by track irregularities or train - to - train interactions. The vibration amplitude is precisely controllable, with a range of 0.1 mm to 20 mm (peak - to - peak), enabling the reproduction of different levels of vibration intensity.
  • It can generate vibrations in multiple axes, including vertical, horizontal, and rotational axes. Rail transit communication signal equipment is often exposed to complex multi - directional forces. For example, equipment installed on the train may experience vertical vibrations from the movement of the wheels on the tracks, horizontal vibrations during acceleration and deceleration, and rotational vibrations due to the train's turning. The multi - axis vibration capability of the shaker provides a more realistic simulation of these actual mechanical stresses, helping to identify potential weak points in the equipment'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 transit communication signal equipment is likely to face. For instance, a profile can be designed to simulate the vibrations during a typical rail journey, including the start - up, cruising, and braking phases, as well as the vibrations during emergency stops or when passing through areas with poor track conditions. The ability to customize these profiles ensures that the testing is as realistic as possible, closely replicating the conditions in the rail transit 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 communication modules to larger signal control units, accommodating the diverse sizes and weights of rail transit communication signal equipment.

Climatic Test Chamber

• Comprehensive Climatic Simulation
  • The climatic test chamber integrated with the vibration shaker can create a wide range of climatic conditions. The temperature can be adjusted from extremely low values, such as - 40°C to simulate cold regions, to high temperatures of up to + 80°C to mimic hot and humid climates or the heat generated in confined spaces near signal equipment. 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 other climatic factors such as rain, snow, and dust exposure. In rail transit, communication signal equipment may be exposed to harsh weather conditions, and the ability to simulate these conditions is essential for evaluating the equipment's durability and performance. For example, simulating rain can help identify potential water ingress points in the equipment, while dust exposure testing can assess the effectiveness of dust - proof seals.
• Rapid Climatic Transitions
  • Rail transit communication signal equipment may experience sudden changes in the climate, such as moving from a cool, dry station to a hot, humid tunnel or vice versa. 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 be a significant stress factor in its operation.
• Large and Uniform Test Volume
  • The climatic 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 transit communication signal equipment, from individual devices to complete sub - systems. The chamber is designed to provide uniform climatic 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 equipment 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 climatic 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 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 and technicians 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 transit industry, where testing may need to be conducted in large maintenance depots or along extensive rail networks. 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.
