As a core part of automotive safety evaluation, how the steering column performs at the moment of collision has a direct bearing on the driver's life safety. The Haythammonocular 3D high-speed visual strain gaugeHow does it help optimize structural safety?

Test Preparation

• Apply a clear speckle pattern to the steering column surface to ensure measurement accuracy

• Adjust the position and angle of the visual strain gauge to ensure the impact process is fully recorded.

Impact Test

• Use the impact testing device to apply the specified simulated collision force.

• Monocular 3D DIC TechnologyReal-time recording of strain, displacement, velocity, and acceleration information on the steering column surface.

Data Analysis

• Displacement measurement: Clearly presents the deformation trajectory of the steering column and analyzes the overall safety of the structure.

• Velocity analysis: Quantifies the velocity change of the structure during impact and evaluates the material's capacity to absorb impact energy.

• Acceleration analysis: Determines the transmission path of the impact force and reduces the risk of secondary injury to the driver.

 Testing Value

• Deformation trend analysis: Grasps the loading state of the steering column and optimizes safety design.

• Impact absorption verification: Evaluates the cushioning capacity of the steering column under impact force.

• Data-driven optimization: Adjusts materials and structure based on measurement data to improve safety.
