Energy destruction system for vehicle simulated crash tests - with pneumatically controlled braking device providing programmed retardation function

摘要

The system uses short-term braking of a movable object (1) via a braking device with a braking surface (3) provided by the object and a braking layer (4) controlled hydraulically to control the braking force. Pref. the braking surface extends at an angle to the direction of movement of the object, the braking layer carried by the piston (6) of a hydraulic cylinder (7), coupled to a braking control valve (9), regulated by a programmed braking control (12). ADVANTAGE - Provides relatively low-cost crash simulation testing with given retardation function.
