Abstract

The invention relates to a liquid drop impact experiment device, in particular to a liquid drop impact experiment device for quantitatively controlling deformation and tension of a flexible substratethrough ventilation, and belongs to the field of liquid drop impact behavior control. The device comprises a droplet generation system, a substrate deformation control system, a high-speed imaging system, a lifting platform and a test bed, wherein the liquid drop generation system is used for generating liquid drops meeting experimental conditions, the substrate deformation control system is usedfor quantitatively controlling deformation and tension of the flexible substrate through ventilation, and the high-speed imaging system is used for capturing an impact process of the liquid drops anda substrate deformation process. The droplet impact experiment device has the beneficial effects that the defect that only the structure of the substrate can be replaced or modified when the elastic or flexible performance parameters of the substrate need to be adjusted in an existing experiment device is overcome, and the droplet impact experiment device is suitable for development of a large number of parameterized experiments and is beneficial to effective regulation and control of droplet impact behaviors.

Description

technical field [0001] The invention relates to a liquid drop impact experimental device, in particular to a liquid drop impact experimental device for quantitatively controlling the deformation and tension of a flexible substrate by ventilation, and belongs to the field of liquid drop impact behavior control. Background technique [0002] After the droplets hit the solid surface, they will stick, spread, rebound or even break. In industrial and agricultural production, on the one hand, it is necessary for the droplets to quickly detach or roll off the substrate surface, such as: the surface of anti-fouling products, car windshields, anti-corrosion Ice coating, etc.; on the other hand, it is required that the droplets can adhere to or even spread on the substrate surface. For example, the quality of thermal spraying depends on the adhesion of metal droplets; pesticides sprayed on plants not only require droplets to adhere to the plants, but also Spread to a certain extent to...
