Introduction
Automotive crash testing is a core method for evaluating vehicle passive safety performance. As a key link in data acquisition, sensor selection and application directly affect the accuracy and reliability of test results.
I. Common Sensor Types
1. Accelerometers
Used to measure acceleration changes in vehicle body and dummy parts during crashes. Consider range, frequency response, and shock resistance when selecting.
2. Force Sensors
Used to measure crash forces, seatbelt loads, etc. Pay attention to overload capacity and mounting stiffness matching.
3. Displacement Sensors
Primarily for measuring body deformation and dummy displacement. Non-contact optical measurement is recommended.
II. Installation Guidelines
Sensor mounting position, fixing method, and signal shielding are critical. Refer to SAE J211 standard for standardized operations.
