• Precision Temperature and Vibration Control Systems

  • Temperature Control: Capable of achieving a wide temperature range, typically from -60°C to +150°C, with an accuracy of ±0.5°C. The system utilizes advanced refrigeration units, heaters, and a sophisticated control algorithm to ensure rapid and accurate temperature cycling. This allows for the simulation of extreme cold and hot conditions that automotive components may encounter, such as in arctic regions or near engine bays.

  • Vibration System: The chamber is equipped with a high-performance vibration platform that can generate 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 designed to replicate various real-world vibration sources, including engine vibrations, road surface irregularities, and the dynamic forces experienced during vehicle operation. The vibration control system is highly precise, allowing for the programming of complex vibration profiles and the ability to adjust the vibration intensity and frequency in real-time.

• Intuitive Control Panel and Data Acquisition Interface

  • The control panel is user-friendly and provides operators with easy access to all test parameters. They can set and adjust temperature cycling profiles, vibration frequencies, amplitudes, and test durations with minimal effort. The panel also displays real-time information about the current temperature, 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 temperature histories, vibration waveforms, and any observable changes in the performance or integrity of the automotive 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

  • 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-temperature and over-vibration protection systems, emergency stop buttons, and alarms for abnormal temperature 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

• Temperature Range and Accuracy

  • The -60°C to +150°C temperature range with ±0.5°C accuracy enables the evaluation of automotive components in a wide spectrum of thermal conditions. This is crucial as different materials and components may have varying thermal expansion coefficients and performance characteristics at different temperatures. For example, metal parts may become brittle at extremely low temperatures, while plastic components may soften or degrade at high temperatures. The accurate temperature control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.

• Vibration Parameters

  • The vibration system can produce frequencies from 5 Hz to 2000 Hz and amplitudes up to 50 mm. These parameters can be adjusted to mimic different driving conditions and vibration sources. For instance, low-frequency vibrations around 5 - 20 Hz can simulate the rumbling of a vehicle on a rough road, while high-frequency vibrations in the range of 500 - 2000 Hz can replicate the vibrations from an engine or a high-speed rotating component. The ability to precisely control the vibration frequency and amplitude is essential for a comprehensive assessment of the component's resistance to vibration-induced failures.

• Temperature Cycle Profile and Vibration Synchronization

  • The chamber allows for the programming of complex temperature cycle profiles in conjunction with vibration. For example, it can simulate a scenario where a component is subjected to rapid temperature changes while simultaneously experiencing vibration. The temperature cycle can be set to mimic daily or seasonal temperature variations, such as a cold start in the morning followed by a rise in temperature during operation and then a cool-down period. The vibration and temperature cycling can be synchronized to replicate real-world conditions more accurately, providing a more comprehensive and realistic test environment.

• Testing Volume and Payload Capacity

  • The testing volume can be customized, usually ranging from 3 m³ to 15 m³, depending on the size of the automotive components to be tested. The payload capacity is designed to handle heavy and bulky components, with a maximum capacity of up to several tons. This allows for the testing of a wide range of automotive parts, from small electronic components to large engine and chassis assemblies.

• Data Sampling Frequency and Resolution

  • The data acquisition system samples data at a frequency of up to 1000 Hz. The temperature data has a resolution of 0.1°C, vibration frequency data has a resolution of 0.1 Hz, and vibration amplitude data has a resolution of 0.1 mm. This high-resolution and frequent sampling enable the detection of even the slightest changes in temperature and vibration, providing valuable insights into the behavior of the automotive components during the test.

4. Product Functions

• Accurate Simulation of Real-World and Accelerated Conditions

  • The chamber replicates the combined effects of vibration and temperature cycling that automotive components experience during their service life. By subjecting the components to these realistic and accelerated stress conditions, manufacturers can identify potential failures and weaknesses that may not be apparent under normal operating conditions. This helps in improving the design and manufacturing processes to enhance the overall reliability and durability of the components.

• Product Design Optimization and Quality Control

  • Through a series of tests on different automotive 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 and temperature cycling. The chamber also serves as a critical tool for quality control, ensuring that each production batch of components meets the required standards for durability and performance. For example, if a particular component shows signs of cracking or malfunction under specific vibration and temperature conditions, the design can be modified to address the issue.
