1. Product Name and Purpose

2. Product Features

• Robust and Customizable Chamber Construction
  • The chamber is built with heavy-duty materials to withstand the intense forces generated during pressure vibration testing. The walls are made of high-strength steel with excellent sealing properties to maintain the required pressure levels. The interior is designed to accommodate a wide variety of automotive components, from small electronic modules to larger mechanical assemblies. The door is equipped with a reliable sealing mechanism and a viewing window, allowing operators to closely monitor the testing process. The chamber can be customized in terms of size and internal layout to meet specific testing needs.
• Precision Pressure and Vibration Control Systems
  • Pressure Control: Capable of achieving a wide range of pressures, typically from vacuum levels up to several atmospheres, with an accuracy of ±0.1% of the set value. The system utilizes advanced pressure pumps, valves, and sensors to ensure accurate and stable pressure regulation. This allows for the simulation of different pressure environments that automotive components may experience, such as those in fuel systems, hydraulic circuits, or in high-altitude or deep-sea driving conditions.
  • Vibration System: The chamber is equipped with a high-performance vibration platform that can generate a broad spectrum of vibration frequencies and amplitudes. It can produce vibrations from 5 Hz to 2000 Hz with amplitudes up to 50 mm. The vibration system is designed to replicate various real-world vibration sources, including engine vibrations, road surface irregularities, and the dynamic forces associated with vehicle maneuvers. The vibration control system is highly precise, enabling the programming of complex vibration profiles and real-time adjustments.
• Intuitive Control Panel and Data Acquisition Interface
  • The control panel is user-friendly and provides easy access to all test parameters. Operators can set and adjust pressure levels, vibration frequencies, amplitudes, and test durations with minimal effort. The panel also displays real-time information about the current pressure, vibration status, and any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data. This includes pressure histories, vibration waveforms, and any observable changes in the component's performance or integrity. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats.
• Safety Features and Alarms
  • To ensure the safety of operators and the protection of the test specimens and the chamber itself, a range of safety features is incorporated. These include over-pressure and over-vibration protection systems, emergency stop buttons, and alarms for abnormal pressure fluctuations, vibration malfunctions, or any other equipment failures. The chamber is also equipped with proper ventilation and exhaust systems to handle any potentially harmful gases or vapors that may be generated during the testing process.

3. Specific Parameters

• Pressure Range and Accuracy
  • The wide pressure range from vacuum to several atmospheres with ±0.1% accuracy enables a comprehensive evaluation of automotive components. For example, fuel injectors need to function properly under different fuel pressure conditions, and seals must hold up against varying pressure differentials. The accurate pressure control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.
• Vibration Parameters
  • The vibration system's ability to produce frequencies from 5 Hz to 2000 Hz and amplitudes up to 50 mm allows for the replication of diverse driving conditions. Low-frequency vibrations can mimic the rumble of a rough road, while high-frequency vibrations can simulate the rapid oscillations of an engine or a high-speed rotating component. The precise control of vibration frequency and amplitude is essential for a thorough assessment of the component's resistance to vibration-induced failures.
• PVT Cycle Parameters
  • The GMW14785 PVT Cycle Test involves specific combinations of pressure and vibration profiles. The chamber can be programmed to execute these cycles accurately, including the sequence and duration of pressure changes and vibration applications. For instance, a component may be subjected to a series of pressure pulses while simultaneously experiencing a particular vibration frequency and amplitude, and the chamber can precisely replicate such complex scenarios.
