Environmental Test Walk In Chambers For ISO 12097-2 Road Vehicles Airbag Modules

1. Product Name and Purpose

2. Product Features

• Robust and Secure Chamber Construction
  • The chamber is built with heavy-duty materials to withstand the rigors of airbag module testing. The walls are made of high-strength steel with excellent insulation properties to maintain stable internal conditions. The interior is designed to be shock-absorbent and fire-resistant to handle the potential forces and heat generated during airbag deployment. The door is equipped with a reliable sealing mechanism and a safety interlock system to prevent accidental opening during testing. The overall structure is engineered to contain any debris or fragments that may result from a malfunctioning airbag module.
• Precision Environmental Control Systems
  • Temperature Control: Capable of achieving a wide temperature range from -40°C to +80°C with an accuracy of ±0.5°C. The system utilizes advanced refrigeration and heating units, along with multiple temperature sensors, to ensure uniform temperature distribution throughout the chamber. This allows for testing of airbag modules in extreme cold and hot conditions, simulating various climates and vehicle operating environments.
  • Humidity Control: The humidity range extends from 10% to 95% relative humidity, with an accuracy of ±3% RH. A combination of humidifiers and dehumidifiers, coordinated by a sophisticated control algorithm, enables precise humidity adjustments. High humidity can affect the electrical components and chemical propellants in airbag modules, while low humidity may cause drying and cracking of materials, so accurate humidity control is essential.
  • Vibration System: Integrated vibration platforms can generate a variety of vibration frequencies and amplitudes, simulating the vibrations experienced during vehicle operation, such as those from the engine, road surface, and drivetrain. The vibration system can also replicate the specific vibration patterns associated with different types of collisions, providing a more comprehensive evaluation of the airbag module's resistance to vibration-induced failures.
  • Shock Testing Capability: The chamber is equipped with a shock generator that can produce controlled shock pulses with varying magnitudes and durations. This allows for the simulation of crash impacts and the assessment of how airbag modules respond to sudden and severe shocks. The shock testing system can be adjusted to meet the specific requirements of different vehicle types and crash scenarios.
• Intuitive Control and Data Acquisition Interface
  • The control panel is user-friendly and allows operators to easily set and adjust test parameters. It provides real-time displays of the current environmental conditions, including temperature, humidity, vibration frequency and amplitude, and shock characteristics. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data. This includes temperature and humidity histories, vibration profiles, shock waveforms, and any changes in the performance or integrity of the airbag modules. 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 and over-pressure 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, shock irregularities, or any other equipment failures. The chamber is also equipped with ventilation systems to ensure the safe removal of any potentially harmful gases or vapors that may be released during airbag deployment or due to chemical reactions.

3. Specific Parameters

• Temperature Range and Accuracy
  • The -40°C to +80°C temperature range with ±0.5°C accuracy enables the evaluation of airbag module performance in a wide range of thermal conditions. This is crucial as airbag components, such as the inflator and the fabric, may be affected by temperature extremes. For example, in cold temperatures, the propellant in the inflator may have reduced reactivity, while in hot temperat
