| Abstract: |
| The measurement of the deformation of the rubber ball colliding with steel plate was studied using high-speed camera and image processing technology.Firstly，threshold segmentation method was used to segment the captured image，the edge contour of the segmented image was extracted，and the least -squares method was used to fit the circle of the edge to obtain the center coordinates of the ball image. Then，by calculating the image scale，initial collision time and end collision time based on the characteristic that the acceleration of the rubber ball when it falled was the gravitational acceleration，the deformation of the rubber ball could be calculated.Finally，according to the deformation measurement results of the rubber ball，it was found that the collision process of the rubber ball was a small deformation collision process（maximum deformation was not exceeding 1.3 mm）.The deformation of the rubber ball increased with the increase of the falling height and ball diameter，decreased with the increase of rubber material hardness.This study provided a reference method for measuring small deformations in rubber ball collisions，which layed the fundation for the analyzing of the collision characteristics and the establishment of contact force models for rubber materials. |
