An electromechanical brake is disclosed, configured such that a piston pulls a brake pad toward a wheel disc via a drive motor. The electromechanical brake includes: a hysteresis data storage unit storing rising interval function data over a rising interval and falling interval function data over a falling interval, wherein the braking force increases as the piston moves toward the wheel disc and decreases as the piston moves away from the wheel disc; a position detection unit detecting the position of the piston; a calculation unit calculating the differential value of the detected piston position relative to time; a past state data storage unit storing data over a previous interval corresponding to the previous piston position; and a braking force calculation unit calculating the braking force based on the differential value of the piston position and the data over the previous interval.

The invention discloses a method for calculating the water entry slamming pressure of an open cavity in waves, relates to the technical field of ocean engineering, is used for predicting the water entry process of the open cavity, and comprises the steps of constructing a geometric model of the open cavity, constructing a wave field, and simulating the movement process of a target cavity entering the wave field and the movement process of the target cavity in the wave field. Constructing a time domain motion equation of the target cavity, solving the time domain motion equation of the target cavity by adopting a numerical integration method, and calculating a hydrostatic pressure component, an entry water impact dynamic pressure component, an in-cavity air fluctuation pressure component and a wave induction dynamic pressure component of the target cavity; and performing decoupling calculation on the water entry slamming pressure of the target cavity based on the four sub-components.
