A real-time capture system for simulating the fusion process of metal droplets under microgravity

Abstract

The invention provides a real-time capture system for simulating the metal droplet chasing and fusion process under microgravity, and solves the insufficiency of the existing drop tube technology that cannot complete the metal droplet fusion test in the microgravity environment. A real-time capture system for simulating the pursuit and fusion process of metal droplets under microgravity comprises a tube body, a main body support frame, a microgravity droplet pursuit and fusion module, a microgravity droplet pursuit and fusion real-time capture module, an image processing module, a collection module and a vacuum pumping module. With the inert gas supplement module; the tube body is vertically fixed by the main support frame, which is connected with the vacuum and the inert gas supplement module to create an inert gas environment in the tube body, the microgravity droplet pursuit fusion module, the microgravity droplet pursuit fusion module The real-time capture module and the collection module are arranged in sequence from top to bottom along the height direction of the pipe body.

Description

technical field [0001] The invention relates to the technical field of space metal droplet 3D printing, in particular to a real-time capture system for simulating a metal droplet chase and fusion process under microgravity. Background technique [0002] The uniform metal droplet jet printing technology generates uniform metal droplets through the droplet ejector, and controls the movement of the three-dimensional substrate at the same time, so that the metal droplets are accurately deposited in a specific position, fused with each other, solidified, and "stacked" point by point layer by layer. Rapid printing of three-dimensional structures; it has the advantages of not requiring expensive high-power energy sources and special equipment, no special metal raw materials, and controllable size of metal droplets. [0003] However, the fusion effect of metal droplets in a microgravity environment (collision fusion of molten droplets and solidified droplets), and whether the perfor...
