    摘要: Provided is a destructive inspection method and a quality determination method of vitreous silica crucible capable of inspecting in a condition as close as possible to the actual status of use.
    The destructive inspection method of the vitreous silica crucible according to the present disclosure, evaluates a crack state of an inner surface of a vitreous silica crucible 1 for pulling a silicon single crystal supported by a graphite susceptor 2 when a load is instantaneously applied to one point on the inner surface via an automatic center punch 10 while pushing the tip portion of the automatic center punch 10 against the inner surface.

    摘要: The invention relates to a method for operating a test device (100) and to a test device (100) for simulating motor vehicle crashes, wherein the test device (100) has a carriage arrangement (110) which is arranged so as to be displaceable along a rail arrangement; a test setup which is arranged on the carriage arrangement (110) and has at least one motor vehicle component to be tested; and an acceleration unit (120) by means of which a force can be transmitted to the carriage arrangement (110) in order to accelerate the carriage arrangement (110). The acceleration unit (120) has a hydraulic drive cylinder (122) with a piston (123) and a piston rod (121) which is connected to the carriage arrangement (110). In order to ensure that a simulation of accident situations can be improved in a way which is easy to implement but nevertheless reproducible, according to the invention, at least one measuring pickup (126, 127) is provided for sensing a pressure (P1, P2) which acts in the piston-side region (128) and/or in the piston-rod-side region (129) of the drive cylinder (122), and further that a control device (150) is provided which is configured to set a quantity of hydraulic fluid which is fed into the piston-side region (128) of the drive cylinder (122), per time unit, as a function of the pressure sensed in the drive cylinder (122), and/or which is fed into the piston-rod-side region (129) of the drive cylinder (122), or discharged therefrom, per time unit, as a function of the pressure sensed in the drive cylinder (122), in such a way that an acceleration force which is transmitted to the carriage arrangement (110) assumes a value which is defined or can be defined in advance.

    摘要: It permits low velocity impacts to be applied with high precision, offering a wide range of energies, internal or external application, from any angle of incidence and measuring the energy delivered and returned.
    It includes an impactor element (1) coaxially joined to a launcher element (11) and both in turn to a base structure (27). In the primed position this assembly is linked by means of some pivoting catches (24) and actuators (43), governed by the control system for the machine. The impactor (1) has in its central body (2) a flange (7) which is retained in the pivoting catches (24) and in its rear end it includes a propulsion valve assembly (4). The launcher element (11) includes the tube (10) of the pneumatic propulsion cylinder, with two side windows (12) for the passage of the valve retainer (13), others with two side windows (19) for the passage of the retaining yoke (20) of the emergency energy absorber (39).

    摘要: Un dispositif, conçu essentiellement comme un adaptateur pour des machines d'essai universelles, permet à de telles machines d'effectuer des essais de traction par impulsion sur des éprouvettes textiles et autres. Le dispositif utilise des ressort (17, 18) qui sont précomprimés, verrouillés puis libérés pour déplacer une traverse mobile (10) par rapport à une traverse statique (11). Des mâchoires de serrage (28, 29) sur chaque traverse sont amovibles pour changer et faciliter le montage des éprouvettes. La mise sous pré-tension est assurée par réglage des vis des mâchoires de serrage des éprouvettes. Des transducteurs piézoélectriques (51) fournissent une mesure de la tension des éprouvettes à chacune de leurs extrémités pour apprécier les effets d'ondes de choc.

    摘要: Ein hydraulischer Belastungszylinder, insbesondere für Katapultanlagen, mit einem Kolben (Differentialkolben), der auf einer Seite eine nach außen gehende Kolbenstange aufweist, so daß seine Kolbenflächen (Kreisfläche/Ringfläche) unterschiedlich groß sind, einer hydraulischen Druckmittelquelle zur Betätigung des Belastungszylinders bzw. Kolbens sowie einem Absperrventil in der Verbindungsleitung zwischen Druckmittelquelle und Belastungszylinder soll vereinfacht werden und insbesondere mit einem einfachen Ventil betrieben werden können. Der Belastungszylinder soll darüber hinaus auch als doppelt wirkender Zylinder verwendbar sein. Dies wird dadurch erreicht, daß die Druckmittelquelle (10, 15) mit der durch die kleine Kolbenfläche (2a) begrenzten Zylinderkammer (4a) (Ringkammer) unmittelbar und mit der durch die große Fläche (2b) begrenzten Zylinderkammer (4b) über das Absperrventil (20, 30) oder ein geeignetes Steuerventil verbunden ist. Mit dem Absperrventil kann der Zylinder mit Differentialkolben besonders schnell betätigt werden. Mit einem geeigneten Steuerventil können in beiden Bewegungsrichtungen des Kolbens an der Kolbenstange die gleichen Kräfte erzeugt werden.
