Device and method for measuring collision process in laser shock high-speed forming of plate

The invention discloses a device and a method for measuring a collision process in laser shock high-speed forming of a plate, and belongs to the technical field of measurement. The device comprises alaser forming system and a measuring system, wherein the laser forming system comprises optical glass, a laser, an absorption layer, a metal sheet, a metal round bar, a barrier film, insulating paperand a female die. The method comprises the following steps of: firstly, enabling a metal die not to be in direct contact with the metal sheet and the metal round bar by adopting the insulating paper and the barrier film; correspondingly connecting the metal sheet and the metal round bar with a positive electrode and a negative electrode of a power supply; enabling the metal sheet to be in contactwith the metal round bar after being subjected to laser shock deformation; and conducting a measuring loop, wherein the number of generated voltage pulse signals is the collision frequency of the metal sheet moving at a high sp
