Abstract: A dummy for simulating human physical behaviour during a test, comprising artificial human body elements that are mutually connected, the body elements having deformation properties, wherein a deformation property of a body element is actuatably variable. The dummy comprises an actuator for varying a deformation property. The actuator may comprise a fluidic driver.

Abstract: A multi-point hydraulic suspension system for a land vehicle has two or more individual hydraulic actuators. These two or more actuators are each operatively arranged between a suspended structure and a wheeled base of the land vehicle for relative positioning one another. A common supply of pressurized fluid has a given pressure and a selectively operable pump with an inlet and an outlet, for increasing the given pressure of the common supply of pressurized fluid. A fluid reservoir is in selective fluid communication with the inlet of the pump. Controllable valve means are interposed between each of the two or more actuators and the common supply of pressurized fluid for selectively bringing each of the two or more actuators into fluid communication with the common supply of pressurized fluid in response to a control unit for controlling the valve means and the pump.

Abstract: The invention relates to an active suspension assembly and a vehicle equipped therewith. The assembly comprises a bearing arm, spring and adjusting mechanism. In use, the bearing arm supports the second vehicle mass, for instance a cabin or wheel and is pivotally connected to the first vehicle mass, for instance a chassis, around a pivot axis; the spring mechanism produces a spring force that exerts a counter moment on the bearing arm that can counterbalance any external moment acting on said bearing arm; and the adjustment mechanism is arranged to vary said counter moment by altering the direction of the spring force and/or move its point of application in a first direction. The adjustment mechanism is furthermore arranged to move the point of application of the spring force in a second direction, in which the counter moment is not or hardly affected, but by which the effective spring stiffness of the suspension assembly is affected.
