Consists of a bed 1 and wings 2 on both the axis of rotation 3 as the pliers 4 of the brake, an arm 6 dr through holes 10 and a mass supported 7 sliding through the arm 6 and fixed on it, and finally an interchangeable impactor 11 is screwed into the mass 7.
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 tip of the impactor 11 is an interchangeable tip that binds to the mass 7 by a threaded connection.
This plate is required due to the large dimensions of the pendulum.
The joint system of the bed is set based on the specimen to impact. EP EPA1 en El control del sistema frena el dispositivo una vez ejecutado el impacto. Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself hcarpy displayed.

Figures 3 and 4 show examples of system junction impacts on a test bench. This angle dee be any: 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 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 method 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 disposed at the end of the arm.
The pneumatic system is lower consumption and a smaller electric braking system. It is detected when the rotation of the device changes direction after impact. The dough is firmly joined to the arm via a connecting bolt passing through both. Brake disks 5 are supported on the shaft 3 xe arranged with wings 2 of the bed.
Thus it is achieved that the movement of both elements is integral. It is another object of the invention is that the brake tire, are available chapy the axis and its instantaneous actuation input better yields to impact and avoid rebound effect after the blow with the specimen.
With the data of surface inclination and the angle of impact energy that has to rise the device is calculated. Said device is provided with a braking system which controls the height of the impact once defined the energy ed with which will impact and similarly this braking system avoids rebound after impact. 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 angle of the surface on which is to impact measured with an inclinometer. 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.
Country carpy ref document: The software associated with the device xe brakes the pendulum when it has reached the desired angle. The method followed for use is as follows: Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada.
ESB1 – Pendulum device for testing low energy impact – Google Patents
El brazo 6 tiene agujeros 10 en su superficie marcando las diferentes posiciones en las The arm 6 has holes 10 on its surface marking the different positions in the. To solve this and other problems has developed the pendulum impactor of the invention. Esta es una de las This is one of the. The angle transducer 12 to the shaft 3 is also connected on the outside thereof and measures the angle that rotates the pendulum.
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. Pendulums are characterizations of materials for the Charpy method where the resistance is measured at break of a specimen when impacted using a pendulum with a hammer on the end.
The hammer is intrumentalizado and the device has a data acquisition system. The object of this device is to perform controlled in the specimen, in no case cause breakage or excessive damage to the damage.
The utility model has a Charpy pendulum whose main characteristic is the support plate which actuators pendulum support. Impact pendulum-type testing machine for testing samples of materials with repeated impacts. 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. Is screwed on the mass notch: In Figures 3 a practical embodiment of the invention is shown wherein the device anchor in one of the columns of a portico.
The bank has a design that allows installation anywhere: From airplane wings, boats etc. The device is compact and versatile and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction. Braking system control device once executed the impact. The advantages of the device of the invention are: 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.
Kind code of ref document: Are arranged Tong anchored in the wings of the bed to leave the ajgulo of free bed and can easily be tied to any surface. In the state of the art impact devices pendulum they are mainly used for destructive testing.
