The invention discloses a semi-active safety control method for suspension systems of high-speed trains. The semi-active safety control method can lower the derailment factor in the running process of the high-speed trains and improve the safety in the high-speed running process of the trains. According to the invention, on the basis of the traditional skyhook damper control method, the wheel-rail horizontal acting force closely related to the derailment factor of the trains is added to serve as an input variable, and the brand-new semi-active control method is built. The semi-active safety control method can effectively restrain horizontal vibration of wheel sets and bogies in the running process of the trains, lower the derailment factor in the running process of the trains and greatly improve the safety in the running process of the trains. In addition, the semi-active safety control method is easy to implement, is successfully applied to the suspension systems of the high-speed trains and can help to achieve intelligent control over the high-speed trains.
