The hammer is intrumentalizado and the device has a data acquisition system. De esta manera se consigue que el movimiento de ambos elementos sea solidario. Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada.
Mediante un pulsador se libera el brazo y se ejecuta el impacto. 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 disposed at the end of the arm.
The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. In relation to the arm and the mass, the mass is displaced and fixed along the arm as the impact energy needed.

The tip of the impactor 11 is an interchangeable tip that binds to the mass 7 by a threaded connection. Se detecta cuando el giro amgulo dispositivo cambia de sentido tras el impacto. It then goes on to describe very briefly a series of drawings which aid in better understanding the invention and which are expressly related to an embodiment of said invention presented as a non-limiting example thereof.
The bank has a design that allows installation anywhere: El control del sistema frena el dispositivo una vez ejecutado el impacto. Wind tunnel test method to study out-of-service tower crane behaviour in storm winds.
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 antulo transducer 12 detects that exceeds a certain level or a change of angle of the mass 7 occurs.
The flexibility in use, with easy adaptation to different places set, to be a portable device. 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.
Also on ed axis of rotation 3 the arm 6 ending in a mass 7 constituting anggulo the pendulum is fixed. The object of this device is to perform controlled in the specimen, in no case cause breakage or excessive damage to the damage.
It is an object of the invention to establish different test parameters depending on the type of material and the notch of the hammer, providing the pendulum of a single arm adapted for the mass of the recess can be moved by it and located in different positions. 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 determine the most appropriate inertia.
The different positions can take the mass 7 increase system flexibility because different impact energies are achieved by moving the mass 7.
Binding arm 6 with the axis 3 is consolidated with oblique supports 8 and the corresponding part of the shaft 3 at its junction with the arm 6 and two oblique supports 8 changes its cylindrical design for a rectangular design where the connecting points 9 are established.
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. Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. Kind code of ref document: In the state of the art impact devices pendulum they are mainly used for destructive testing. Sobre la masa va atornillada la entalla: The method of using the aforementioned pendulum device solves the problems that may arise in the execution of all types of impacts with this device.
Country of ref document: The angle transducer 12 to the shaft 3 is also connected on the outside thereof and measures the angle that rotates the pendulum.
Impact pendulum-type testing machine for testing samples of materials with repeated impacts. The brake comprises two brake discs attached to the shaft and two pneumatic grippers. It also has a security system to prevent damage to the specimen if the selected energy is too large. The advantages of the device of the invention are: EP EPA1 en Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed.

ES Kind code of ref document: Adaptability to any test site for the use of an efficient air braking system. 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.
Is screwed on the mass notch: 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. 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. The impact energy to be performed on the specimen.
Other similar systems studied to date are designed for impact on specimens or specimens of small size that are placed on the pendulum device itself. This angle can be any: It is detected when the rotation of the device changes direction after impact. Pendulum device for testing low energy impacts the type used for characterization of materials by the Charpy method, characterized by having a control system which prevents recoil or rebound further damage on the desired material.
Device pendulum impact test low energy according to the first claim, characterized in that the various means for fixing the bed 1 outside the wings 2magnetic media, based clamps or screw connectionsallow. The utility model has a Charpy pendulum whose main characteristic is the support plate which actuators pendulum support.
En este caso se trata de resolver la necesidad de ampliar el rango y el tipo de In this case it comes to solving the need to expand the range and type of.
By a push arm is released and impact run.

The software associated with the device automatically brakes the pendulum when it chxrpy reached the desired angle. The joint system of the bed is set based on the specimen to impact. Are arranged Tong anchored in the wings of the bed to leave the base of free bed and can easily be tied to any surface.
The anguli 4 are supported only in the wings 2 without resting on the bed 1 leaving the maximum area with free access.
