The invention provides a simulation system for an ice-formation condition on a ground, and the simulation system is used for verifying the capacities of preventing/removing ice of tested pieces in an outdoor low temperature environment. The simulation system of the invention comprises a spraying device, a water supplying device, a gas source device, a wind source device and a measurement-control device, wherein the spraying device contains a spraying rod with a nozzle and an affiliated pipeline of the spraying rod, and the affiliated pipeline contains an air inlet pipe and a water inlet pipe; the water supplying device is communicated with the water inlet pipe, and delivers water through purification treatment to the nozzle; the gas source device is communicated with the air inlet pipe, and delivers high pressure air through purification treatment to the nozzle; the wind source device which simulates a wind tunnel delivers uniform and stable airflow to the spraying device; and the measurement-control device controls the whole simulation system, and can display the test parameters in real time. The simulation system for the ice-formation condition on the ground of the invention can simulate the meteorological condition of freezing fog on the ground in the outdoor low-temperature environment, produces water spray with adjustable liquid water content and water droplet diameter, and provides strong guarantee for verifying the capacities of preventing/removing ice of such as a short cabin of an airplane.
