Deformation measurement of military vehicle tire passing through obstacle

Measurement purpose

Measuring the displacement and strain fields on the side of a military vehicle tyre when it passes through different obstacles

Inspection scheme overview

Two phantom V611 high-speed cameras were used to capture the deformed images of tires passing through obstacles. A 1000W high-power light source was independently developed for high-speed light compensation. By analyzing the collected images, the displacement field and strain field of tire deformation can be calculated, which provides a technical basis for evaluating the movement condition under actual working conditions.

Inspection process

（1）Preparing speckle pattern on tire side;

（2）Calibration of two high-speed cameras and acquisition of camera internal and external parameters;

（3）Two high-speed cameras collect data synchronously when tyres pass through different obstacles;

（4）Data analysis and acquisition of displacement and strain fields.

Data analysis

Through the obtained tire deformation data, the overall deformation trend of tire can be clearly analyzed when it crosses different obstacles at different speeds, and the curve data of key points can also be analyzed with high accuracy and high efficiency.
