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.

The tip of the impactor 11 is an interchangeable tip that binds to the carpy 7 by a threaded connection. 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. Device pendulum chrpy 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 prior art as represented several inventions, among which are the following: Device pendulum impact test low energy according to the first claim, characterized by having a pushbutton to release the air cjarpy 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.

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.

The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. The pneumatic system is lower consumption and a smaller electric braking system. 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 advantages of the device of the invention are: Also on the axis of rotation 3 the arm 6 ending in a mass 7 constituting all the pendulum is fixed.


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. 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.

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

ES Kind code of ref document: The device is compact and versatile and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction. 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.

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. 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. 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 avoid rebound effect after the blow with the specimen.

Wind tunnel test method to study out-of-service tower crane behaviour in storm winds. From airplane wings, boats etc.

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

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. 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.

The different positions can take the mass 7 increase system flexibility because different impact energies are achieved by moving the mass 7.

By a push arm is released and impact run. The dough is firmly joined to the arm via a connecting bolt passing through both. 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 ed to determine the most appropriate inertia.

De esta manera se consigue que el movimiento de ambos elementos sea solidario.

Adaptability to any test site for the use of an efficient air braking system. 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.

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 hammer is intrumentalizado and the device has a data acquisition system. 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 having 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.

The test set different parameters depending on the type of material through the use of different masses which can be fixed in different positions, allowing in a simple change of the inertia of the pendulum. It is detected when the rotation of the device changes direction after impact. Mediante un pulsador se libera el brazo y se ejecuta el impacto. 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 bank has a design that allows installation anywhere:
