2. Product Features
Robust and Shielded Chamber Structure
The chamber is constructed with heavy-duty materials that provide excellent protection against external electromagnetic interference. The walls are made of conductive and ferromagnetic materials, which act as a Faraday cage, shielding the internal testing environment from stray electromagnetic fields. The interior is designed to accommodate a wide variety of electrical components, with adjustable racks and fixtures to ensure proper positioning and secure mounting. The door is equipped with a reliable sealing mechanism and a viewing window, allowing operators to monitor the testing process without compromising the integrity of the shielded environment.
Precision Vibration and Environmental Control Systems
Vibration System: Capable of generating a wide range 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 highly precise, allowing for the programming of complex vibration profiles to replicate different driving conditions, such as rough roads, engine vibrations, and high-speed maneuvers. The vibration platform is also designed to provide uniform vibration distribution across the test samples, ensuring accurate and consistent testing results.
Temperature and Humidity Control: The chamber can maintain a wide temperature range, typically from -40°C to +80°C, with an accuracy of ±0.5°C. The humidity control range extends from 10% to 95% relative humidity, with an accuracy of ±3% RH. These environmental controls are essential as temperature and humidity can significantly affect the performance and reliability of electrical components. For example, high humidity can cause corrosion and short circuits, while extreme temperatures can lead to component failure or altered electrical characteristics.
Intuitive Control Panel and Data Acquisition Interface
The control panel is user-friendly and allows operators to easily set and adjust test parameters such as vibration frequency, amplitude, temperature, humidity, and test duration. It provides real-time displays of the current environmental conditions and vibration status, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data. This includes vibration waveforms, temperature and humidity histories, and any observable changes in the electrical performance of the components. 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
Over-temperature, over-humidity, and over-vibration protection systems are in place to prevent damage to the chamber and the test samples. Emergency stop buttons are easily accessible. Alarms are triggered for abnormal temperature fluctuations, humidity levels, 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. Additionally, the shielding of the chamber helps protect operators from any electromagnetic radiation that may be emitted during testing.
3. Specific Parameters
Vibration Parameters
The ability to produce vibrations from 5 Hz to 2000 Hz with amplitudes up to 50 mm allows for a comprehensive evaluation of electrical components. Low-frequency vibrations can mimic the slow oscillations caused by engine idling or driving on a bumpy road, while high-frequency vibrations can replicate the rapid vibrations associated with high-speed rotating components or electrical switching. The precise control of vibration frequency and amplitude is crucial for identifying potential resonance points and weaknesses in the components.
Temperature and Humidity Ranges and Accuracies
The -40°C to +80°C temperature range with ±0.5°C accuracy and 10% to 95% RH humidity range with ±3% RH accuracy provide a wide spectrum of environmental conditions for testing. Electrical components must be able to function reliably across different climates and operating conditions. For instance, a sensor used in a vehicle's engine compartment may experience high temperatures, while a component in the interior may be subject to more moderate temperature and humidity levels. The accurate control of these parameters ensures that the test conditions are realistic and repeatable.
Testing Volume and Payload Capacity
The chamber offers a customizable testing volume, usually ranging from 3 m³ to 15 m³, depending on the size and quantity of electrical components to be tested. The payload capacity is designed to handle a significant amount of components, with a maximum capacity of up to several tons. This flexibility allows for efficient testing of both individual components and complex assemblies.
Data Sampling Frequency and Resolution
The data acquisition system samples data at a frequency of up to 1000 Hz. The vibration data has a resolution of 0.1 Hz and 0.1 mm for frequency and amplitude respectively. The temperature data has a resolution of 0.1°C, and the humidity data has a resolution of 0.1% RH. This high-resolution and frequent sampling enable the detection of even the slightest changes in the test conditions and component performance, providing valuable insights for analysis and improvement.
4. Product Functions
Accurate Simulation of Real-World Conditions
The chamber replicates the combined effects of vibration, temperature, and humidity that automotive electrical components may face during their service life. By subjecting the components to these realistic conditions, manufacturers can ensure that they will perform reliably in the field. For example, a connector that is prone to loosening under vibration and temperature changes can be identified and redesigned before it causes issues in a vehicle.
Product Design Optimization and Quality Control
Through a series of tests on different electrical component prototypes, the data obtained from the chamber can be used to optimize product designs. Engineers can analyze the performance of various materials, geometries, and manufacturing techniques under the combined stress of vibration, temperature, and humidity. The chamber also serves as a critical tool for quality control, ensuring that each production batch of components meets the required standards. If a particular control module shows signs of electrical instability during testing, the design or manufacturing process can be adjusted to correct the issue.
