Adjustment device and method for flexible wall surface suitable for droplet impact

An adjustment device for a flexible wall surface suitable for droplet impact, comprising:

• a base (1) serving for fixing and supporting, a staybolt (4), an experiment substrate (2) and the wall surface to be tested (3), wherein each of the left and right ends of the experiment substrate is provided with two vertical bolt holes (14) at intervals and the experiment substrate is provided on the base (1) through the four staybolts in coordination with the vertical bolt holes;
• the periphery of the wall surface to be tested is fixed to the upper surface of the experiment substrate by an adhesion agent and the inclination angle of the wall surface to be tested is adjusted by adjusting the left two staybolts and right two staybolts on the experiment substrate to different heights;
• and a plurality of through holes (16) are uniformly formed on the experiment substrate below the wall surface to be tested and provided therein with wall surface adjusting bolts (12) used to abut against and apply force to the wall surface to be tested, so as to allow the wall surface to be tested to present a desired curved shape;
• a first guide groove (5) and a second guide groove (6) are formed on the base (1) in parallel with each other and are provided therein with compression springs (7) respectively, sliders (8) are placed in the first guide groove and the second guide groove at the two ends of the compression springs, longitudinal bolt holes (13) are formed on the base (1) at both ends of the first guide groove and the second guide groove and provided therein with longitudinal adjusting bolts (9), and the locations of the sliders in the first guide groove and the second guide groove are adjusted by adjusting the feed amount of the longitudinal adjusting bolts in the longitudinal bolt holes;
• an inner polish hole (15) in coordination with the lower end of the staybolt (4) is formed on the slider.
