The prior art as represented several inventions, among which are the following: EP EPA1 en The brake comprises two brake discs attached to the shaft and two pneumatic grippers. With the data of surface inclination and dw angle of impact energy that has to rise the device is calculated. Sobre la masa va atornillada la entalla: El control del sistema frena el dispositivo una vez ejecutado el impacto.

At the ends of said bed 1 the wings of the bed 2 where the axis of rotation 3 and the brake calipers 4 is mounted are arranged. Braking system control device once executed the impact. Device pendulum impact test low energy according to the first claim, characterized in that the axis of rotation 3 is cylindrical in the portion corresponding to the wings 2 and brake disks 5 and transitions a rectangular binding arm 6 and support points 8 which reinforce said arm 6.

The angle of the surface on which is to impact measured with an inclinometer.

To solve this and other problems has developed the pendulum impactor of the invention. Device pendulum impact test low energy according to the first claim, characterized by having a pushbutton to release the air brake and control system to activate when the angle transducer 12 detects that exceeds a certain level or a change of angle of the mass 7 occurs.

This angle can be any: Specifically, the impact device consists of a pendulum with a system of variable weights are placed in different positions of the arm to provide greater flexibility to the system as to the impact energies that can be set.

Device pendulum impact test low energy according to the first claim, characterized in that the arm 6 and mass 7 are joined by a pin and the mass 7 has an impactor 11 interchangeably by screwing the tip.

Wind tunnel test charpj to study out-of-service tower crane behaviour in storm winds. Patent ES in which a pendulum for testing having a modular configuration, an arm operated by a reducer and characterized motor described because its operation is carried out by operation of an electromagnet that releases the mass se at the end of the arm. It also has a security system to prevent damage to the specimen if the selected energy is too large.

Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada.

Figures 3 and 4 show examples of system junction impacts on a test bench. En este caso se trata de resolver la necesidad de ampliar el rango y el tipo de In this case it comes to chharpy the need to expand the range and type of.

The pneumatic system is lower consumption and a smaller electric braking system. Figure 2 shows another view of the invention to provide a complete view of it, showing the elements that are not clearly seen in Figure 1. Adaptability to any test site for the use of an efficient air braking system.

The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. It is another object of the invention that the xe is provided on a base that is adaptable to any arrangement, either horizontal, vertical, inclined or even on the same specimen.

The grippers 4 are supported only in the wings 2 without resting on the bed 1 leaving the maximum area with free access.


Thus it is achieved that the movement of both elements is integral. Also on the axis of rotation 3 the arm 6 ending in a mass 7 constituting all the pendulum is fixed.

In any case, this and other devices pendulum not adequately solve the problems associated with the location of the specimen when the part to be evaluated is large or problems regarding the use of different types of arms and different body types to anguulo the most appropriate inertia.

The software associated with the device automatically brakes the pendulum when it has reached the desired angle. In the state of the art impact devices pendulum they are mainly used for destructive testing.

Kind code of ref document: If the angle exceeds the impact so that the bulk of the mass 7 can hit the specimen the brake is applied before this happens. The different positions can take the mass 7 increase fharpy flexibility because different impact energies are achieved anguoo moving the mass 7. Is screwed on the mass notch: One kind of pendulum lever Huobujinsen Strain Rate Test device and method loading.

Device pendulum impact test low energy according to the first claim, characterized in that the various means for dd the bed 1 outside the wings 2magnetic media, based clamps or screw connectionsallow. The flexibility in use, with easy adaptation to different places set, to anuglo a portable device. Device for pendulum impact test low energy type used for validations materials Charpy method including a bed on which wings housing the rotation axis arm system is yerguen braking, characterized in that: The dough is firmly joined to the arm via a connecting bolt passing through both.
