The invention provides a test tool and method for simulating a side window pop-up aerodynamic load. The test tool mainly comprises a lifting actuating cylinder, a radial load hydraulic actuating cylinder, a lifting frame, a loading rod, a tool cabin heat-proof sleeve, a tool cabin support, a side window pop-up device, an actuating cylinder lifting rod, a course load hydraulic actuating cylinder and an ignition actuating cylinder. The simulation flight aerodynamic load verification test requirement of the aircraft side window pop-up device can be met; accurate simulation of the aerodynamic load in the side window pop-up process is achieved, and the time-varying aerodynamic load borne by the side window can be simulated according to different ballistic trajectories of an aircraft and different pop-up distances of the side window. The actual installation state is simulated, and details such as coating of heat-proof putty on the surface of an aircraft can be completely simulated. An open structure layout is adopted, operation and test observation are facilitated, the resistance of the side window in the whole pop-up process can be measured through a lifting rod tool, and pop-up of the side window in a pyrotechnic actuating state can be simulated by adopting a pyrotechnic actuating cylinder.
