Automotive Vibration Temperature Humidity Test Chamber Meets IEC 60068

1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The vibration chamber is constructed with a heavy-duty steel frame and insulated panels. The steel frame provides excellent rigidity and stability to withstand the intense vibrations generated during testing. The insulated panels ensure precise control of temperature and humidity levels within the chamber. The insulation material has a low thermal conductivity, minimizing heat transfer from the external environment and allowing for accurate temperature regulation. The chamber is also sealed to prevent any leakage of conditioned air, maintaining a consistent and stable testing environment.
• High-Precision Vibration System
  • Equipped with a state-of-the-art vibration system, the chamber can generate a wide range of vibration frequencies and amplitudes. It can simulate vibrations from low-frequency road bumps to high-frequency engine vibrations. The vibration table is made of high-strength alloy steel and is precisely balanced to ensure uniform and accurate vibration transmission. The system is controlled by a computerized controller that allows for precise programming of vibration profiles. It can generate random vibrations, sine waves, and shock pulses, replicating real-world driving conditions. The vibration amplitude can be adjusted from a few micrometers to several centimeters, and the frequency range can span from 5 Hz to 2000 Hz.
• Advanced Temperature and Humidity Control
  • The chamber features a sophisticated temperature and humidity control system. It is capable of maintaining a wide temperature range, from -40°C to +150°C, with an accuracy of ±1°C. The humidity control range is from 10% to 95% relative humidity, with an accuracy of ±3% RH. The system uses high-quality refrigeration compressors, heaters, and humidifiers/dehumidifiers to achieve and maintain the desired environmental conditions. The temperature and humidity sensors are strategically placed within the chamber to ensure accurate monitoring and feedback control. The control system also has a built-in self-calibration function to ensure long-term accuracy.
• Compliance with IEC 60068 Standards
  • The chamber is specifically designed and calibrated to meet the requirements of IEC 60068, a widely recognized international standard for environmental testing. It can perform various test procedures specified in the standard, such as temperature cycling, humidity testing, combined temperature and humidity testing, and vibration testing. The test parameters, such as temperature limits, humidity levels, vibration frequencies, and test durations, can be easily adjusted to match the specific requirements of different automotive components and testing scenarios. This compliance ensures that the test results are valid and comparable, facilitating product certification and market acceptance.
• User-Friendly Control Interface and Data Logging
  • The chamber is equipped with a user-friendly control interface that allows operators to easily set up and monitor tests. The interface has a touch-screen display that provides real-time information about the chamber's temperature, humidity, vibration status, and test progress. Operators can input test parameters, select test profiles, and start/stop tests with a few simple taps. The chamber also has a built-in data logging system that records all relevant test data, including temperature, humidity, vibration levels, and test times. The logged data can be exported in various formats, such as Excel or PDF, for further analysis and reporting.

3. Specific Parameters

• Maximum Vibration Displacement
  • The chamber can achieve a maximum vibration displacement of ±50 mm. This large displacement range allows for the simulation of severe vibration conditions, such as those encountered during off-road driving or high-speed impacts. For example, when testing the suspension components of a vehicle, a large vibration displacement can help evaluate their durability and performance under extreme conditions.
• Vibration Frequency Range
  • As mentioned, the frequency range of the vibration system is from 5 Hz to 2000 Hz. This wide range covers the frequencies of various vehicle vibrations, from the low-frequency vibrations caused by the rotation of the wheels and the engine's idle speed to the high-frequency vibrations of the transmission and other mechanical components. Testing across this frequency range ensures that all potential resonance frequencies of the components are identified and evaluated.
• Temperature Control Range
  • The chamber can maintain a temperature control range from -40°C to +150°C. This broad range is essential for simulating the extreme temperature conditions that vehicles may experience, from the coldest winter nights to the hottest summer days. For example, electronic components in a vehicle's engine compartment may need to function properly at high temperatures, while exterior components like door handles and mirrors must withstand freezing temperatures.
• Humidity Control Range
  • The humidity control range of 10% to 95% relative humidity allows for the testing of components in different moisture environments. High humidity levels can affect the performance of electrical connectors and cause corrosion, while low humidity can lead to static electricity issues. Testing components at various humidity levels helps ensure their reliability in different climatic regions and operating conditions.
• Maximum Payload Capacity
  • The chamber has a maximum payload capacity of up to 1000 kg. This capacity is sufficient for testing a wide range of automotive components, from small electronic modules to larger mechanical assemblies. It allows manufacturers to test multiple components or a complete vehicle subsystem at once, increasing testing efficiency.

4. Product Functions

• Accurate Evaluation of Component Durability
  • The primary function of the chamber is to provide a precise and reliable assessment of how automotive components will fare when subjected to a combination of vibrations, temperature changes, and humidity levels. By carefully controlling these parameters and following the IEC 60068 standards, it determines the extent of damage or degradation that a component may experience. This information is invaluable for manufacturers to gauge the durability of their products and make design changes to enhance it. For example, a manufacturer of automotive sensors can use the chamber to identify if a sensor's accuracy is affected by temperature and vibration, and then take corrective actions.
• Design Optimization and Validation
  • Through a series of tests on different component prototypes, manufacturers can use the data obtained from the chamber to optimize their designs. They can analyze the performance of various materials, component geometries, and manufacturing processes. For instance, an automotive electronics manufacturer can study the effect of using different types of circuit board materials and soldering techniques on the reliability of a control unit under vibration and temperature stress. By making informed design decisions based on the test results, they can create more robust and reliable components.
• Quality Control and Compliance Testing
  • The chamber is an essential tool for quality control in the automotive industry. It allows companies to ensure that each batch of components meets the required durability and performance standards. It can also be used to conduct compliance testing to meet industry regulations and customer specifications. For example, a vehicle manufacturer may require that all electronic components used in their cars pass a specific set of temperature, humidity, and vibration tests as per IEC 60068, and this chamber can provide the necessary data to prove compliance.
• Research and Development Support
  • In the field of automotive research and development, the chamber offers valuable insights. Researchers can use it to study the fundamental physics of how components respond to environmental and mechanical stresses. They can explore new materials and technologies aimed at improving component durability. For example, a research team may use the chamber to test the performance of a new type of shock-absorbing material for automotive interiors and analyze its potential applications in reducing noise and vibration.
