The invention discloses a device for measuring an impact force of hydraulic oil under laser shock and a method thereof. The device is composed of a laser emission system, a control system and a test system. The laser emission system consists of a pulsed laser device, a plane mirror, a variable-focus lens, and a lens holder. The control system includes a laser controller, a computer, a three-dimensional mobile platform controller, and a hydraulic controller. And the test system consists of a three-dimensional mobile bench, a shell, a test device, a sleeve, a soft film, a limiting layer and a compressing device. According to the invention, a piece of pressure sensing paper is pasted on a compression base plate by transparent epoxy resin; a concentration meter transforms the variable-color red color on the pressure sensing paper into digital data; and pressure analysis software that is compiled by the computer and is installed in the computer transforms the digital data transformed by the concentration meter into a concrete pressure value, thereby obtaining impact forces at all places in an impact range. With the method provided by the invention, the micro-forming impact force caused by laser impacting on hydraulic oil can be measured well. The device and the method are suitable for measurement of the impact force of the hydraulic oil under laser shock.
Description
technical field [0001] The invention belongs to the technical field of metal micro-forming impact force measurement, in particular to a hydraulic oil impact force measurement device and method thereof under laser impact. Background technique [0002] In recent years, the technology of compressing liquid through pulse impact to generate impact force to form tiny parts has received extensive attention. This technology plays a significant role in solving defects such as difficult corner forming in traditional stamping. But today, a simple device for measuring the impact force of a liquid has not yet been invented, using a laser as a pulsed loading force. The liquid has high impact force, short action time and small impact force gradient within the impact range, which brings certain difficulties to the measurement. [0003] The Chinese patent application number 201410272850.7 proposes a method for generating impact step pressure. This patent utilizes the method of compressing...
