Method, device and equipment for creating equivalent virtual road surface

The invention discloses a method, a device and equipment for creating an equivalent virtual road surface, and the method comprises the steps: determining the position of an obstacle on the equivalent virtual road surface according to the fluctuating phase between tires of a whole vehicle when a wheel center is in each stress direction, so as to create the equivalent virtual road surfaces in various shapes; taking the minimum difference value between the obtained test false damage and the target false damage and the minimum difference value between the obtained test real damage and the target real damage after the simulation test is carried out on the equivalent virtual road surface as a target; establishing an equivalent equation and solving by taking the condition that the ratio of the test false damage to the target false damage and the ratio of the test real damage to the target real damage are in a preset ratio interval as a constraint and taking the cycle index, the vehicle speed and the height of an obs
