Abstract On the basis of the internal and external experiences,a single-spraying head simutator with curved-surface,double-lager,variable rainfall intensity spring was developed.Because of the curved-surface design,it can make the water tongue move regularly,so the artificial rainfall is just as like as the natural rainfall.The simulated rainfall process is well-distributed and spraying area is stable.The experiment showed that the mid-raindrop size is of 0.574.26mm,rainfall area is of 150m2,and simulated rainfall intensity ranged 30240mm/h.
