摘要： The invention relates to a spring-damper element (2) for mounting a punching press (1), with a hydraulic damper unit (3) with a first fluid chamber (4) and a second fluid chamber (5), wherein, in the intended operation, a hydraulic fluid is displaced from the first fluid chamber (4) via a throttle point (6) into the second fluid chamber (5) when the spring-damper element (2) is compressed. The damper unit further comprises an overload valve (7) arranged between the first fluid chamber (4) and the second fluid chamber (5), which overload valve opens when a specific fluid pressure is reached in the first fluid chamber (4) or when a specific pressure difference is reached between the first fluid chamber (4) and the second fluid chamber (5) and releases a bypass (8) via which hydraulic fluid then flows from the first fluid chamber (4) into the second fluid chamber (5) bypassing the throttle point (6). Thereby, the spring-damper element (2) is designed in such a way that the fluid pressure or the pressure difference, respectively, at which the overload valve (7) opens can be adjusted when the spring-damper element (2) is installed as intended. With such spring-damper elements according to the invention, it becomes possible to create a mounting arrangement for a punching press, the damping characteristics of which can be adjusted without significant effort, such that a variable operation of the press in wide ranges becomes possible while keeping the ground loading to a minimum in each case.

摘要： An inertial measurement unit includes a housing with openings to permit fluid communication between at least one pressure source and two distinct cavities within the housing. The cavities are separated by an inertial sensor assembly coupled to a vibration isolator assembly. The pressure in the cavities may be adjusted or tuned to change a natural frequency of the inertial measurement unit, thus allowing the unit to be configured and even optimized for a variety of different applications. By adjusting the pressure in the respective cavities, gas squeeze film damping effects may be optimized when the inertial measurement unit undergoes a shock event and/or when the inertial measurement unit experiences vibration loads during operation. In one embodiment, the vibration isolator assembly includes perforations to permit fluid communication between the first and second cavities during specific operational events.

摘要： A method and apparatus for a low-profile suspension system, which provides coarse and fine suspension control to an object supported by the low-profile suspension system. Coarse suspension is provided to adaptively control a position of the object through pneumatic support devices. Pneumatic pressure is adaptively increased in the pneumatic support devices to support an increasing weight of the object, while pneumatic pressure is adaptively decreased in the pneumatic support devices to support a decreasing weight of the object. Fine suspension control is provided through rotational actuation of a shock absorbing device through a right-angle gear drive. By rotationally actuating the shock absorbing device, a range of stroke of the shock absorbing device along a vertical direction is minimized.
