Abstract: A vibration generation device which can vibrate in only one axial direction is used to simultaneously load a vibration force in a plurality of axial directions onto a test piece, and to make it possible to easily modify the proportion of vibration force in each axial direction. The present invention includes: a vibration generation device connection part 1 which is connected to the vibration generation device and is vibrated in a z-axis direction; a first diaphragm 2 which is connected to the vibration generation device connection part 1 and extends in cantilevered form in an x-axis direction intersecting the z-axis direction; a second diaphragm 3 which is connected to the vicinity of an end of the first diaphragm 2 in the x-axis direction, and which extends in cantilevered form in the z-axis direction and a y-axis direction intersecting the x-axis direction; and a test piece installation part 5 on which the test piece is installed and which receives vibrations via the first diaphragm 2 and the second diaphragm 3 from the vibration generation device connection part 1, wherein at least one of the first diaphragm 2 and the second diaphragm 3 has a length adjustment mechanism 6.

Abstract: A multi-axis vibration test system uses a mounting fixture formed from a solid block of Aluminum alloy, at least 20″ per side, and machined to form bearing recesses that receive the pad bearings to overcome the problems of existing systems and deliver the required amplitude of linear displacement over the frequency test band in all three, and possibly six, axes simultaneously and uniformly over the mounting surface(s) for both commercial and the more stringent military standards.

Abstract: A fatigue test assessment method for assessing a suspension point of a cylinder block by means of a fatigue test includes: fixing a suspension point of a cylinder block test piece by using a power assembly installation approach; applying a load to the suspension point of the cylinder block test piece in a preset direction; and determining whether the suspension point of the cylinder block fails. The method can ascertain, by means of assessment during a stage of parts testing, whether the structural strength of a suspension point of a cylinder block meets user requirements, so as to predict and prevent breakage of and faults in the suspension point of the cylinder block, thereby enhancing overall test validity.

Abstract: An apparatus and method for inducing multiaxial vibrations to simulate an environment for transporting a stack of products is provided. A lower platform is provided for inducing uniaxial vibrations. A link is connected to the lower platform by a lower end of the link. The upper end of the link has a universal joint, through which the link is connected to an upper platform. The upper platform has a top surface, on which the stack of products can be placed. In operations, the uniaxial vibrations of the lower platform are transferred to the upper platform through the link and the universal joint, to induce pivotal movement of the upper platform with respect to the shaft of the link. As a result, multiaxial vibrations can be induced to the stack of products placed on the top surface of the upper platform.

Abstract: A shaking unit for the generation of one-dimensional oscillating movements of a machine part mass is provided having a coupling part for mechanical coupling to the machine part mass, a counter-mass which is coupled resiliently to the coupler part and, via the latter, to the machine part mass, and a drive system which acts in a sprung manner between the coupler part and the counter-mass. The coupling part may surround the counter-mass as a frame. At least one of two pneumatic springs of the drive system, which are arranged on both sides of the counter-mass, is loaded with a minimum and/or with a maximum load pressure of the pneumatic springs depending on an oscillation state.

Abstract: The application relates to an apparatus (100) for fatigue testing a wind turbine blade, and to a system and method using such an apparatus (100). The apparatus (100) comprises a base (110) for supporting a first end (12) of the wind turbine blade (10), and an edgewise actuator assembly (120). The edgewise actuator assembly (120) includes a ground-supported edgewise actuator (130) and a flexible cable assembly (140) for connecting the edgewise actuator (130) to the blade (10). The edgewise actuator (130) and the flexible cable assembly (140) are adapted to cyclically deflect the blade (10) relative to the base in the edgewise direction by repeatedly pulling the blade (10) in a substantially horizontal direction.
