Ensayo de Impacto by Alexander E Gomez M on Prezi

Also on the axis of rotation 3 the arm 6 ending in a mass 7 constituting all the pendulum is fixed. The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. 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.

This plate is required due to the large dimensions of the pendulum. The tip of the impactor 11 is an interchangeable tip that binds to the mass 7 by a threaded connection.

ES2473666B1 – Pendulum device for testing low energy impact – Google Patents

The advantages of the device of the invention are: At the ends of said bed 1 the wings of the bed 2 where the axis of rotation 3 and the charpu calipers 4 is mounted are arranged. Se detecta cuando el giro del dispositivo cambia de sentido tras el impacto.

The object of this device is to perform controlled in the specimen, in no case cause breakage or excessive damage to charp damage. Thus it is achieved that the movement of both elements is integral. 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 chwrpy.

Country of ref document: Specifically, the impact dde 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. With the data of surface inclination and the angle of impact energy that has to rise the device is calculated. Wind tunnel test method to study out-of-service tower crane behaviour in storm winds. The joint system of the bed is set based on the specimen to impact.

This angle can be any: 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.

The device is compact and versatile and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction. 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.

The dough is firmly joined to the arm via a connecting bolt anuglo through both. 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.

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 ds said invention presented as a non-limiting example thereof. Impact pendulum-type testing machine for testing samples of materials with repeated impacts. It is another object of the invention is that the brake tire, are available around the axis and its instantaneous actuation input better yields to impact and chary rebound effect after the blow with the specimen.

Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed.

Are arranged Tong anchored in the wings of the bed to leave the chafpy of free bed and can easily be tied to any surface. 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 flexibility in use, with easy adaptation to different places set, to be a portable device. The prior art as represented several inventions, among which are the following: One kind of pendulum lever Huobujinsen Strain Rate Test device and method loading. The method followed for use is as follows: It is detected when the rotation of the device changes direction after impact.

Esta es una de las This is one of the.

The advanced control system that controls a pneumatic brake has a button to release and angle transducer 12 to reactivate when it detects the exceeding of a certain level or angle change of the mass 7.

Figures 3 and 4 show examples of system junction impacts on a test bench. 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. The software associated with the device automatically brakes the pendulum when it has reached the desired angle. 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.

Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada. Other similar systems studied to date are designed for impact on specimens or se of small size angylo are placed on the pendulum device itself. Braking system control device once executed the impact.

Patent ES in which a pendulum for testing having a modular configuration, an arm chrpy 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. Adaptability to any test site for the use of an efficient air braking system.

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