The grippers 4 are supported only in the wings 2 without resting on the bed 1 leaving the maximum area with free access.
With the data of surface inclination and the angle of impact energy that has to rise the device is calculated. Wind tunnel test cbarpy to study out-of-service tower crane behaviour in storm winds.
Pêndulo Charpy
Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed. 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. 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 charph impactor 11 is screwed into the mass 7. The dough is firmly joined to the arm via a connecting bolt passing through both.
In Figures 3 a practical embodiment of the invention is shown wherein the device anchor in one of the columns of a portico. 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. 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. Device pendulum impact test low energy according to the first claim, characterized in that the arm 6 charyp mass 7 are joined by a pin and the mass 7 has an impactor 11 interchangeably by screwing the tip.
It is another object of the invention is that the brake angullo, are available around the axis and its instantaneous actuation input better yields to impact and avoid rebound effect after the blow with the specimen.

Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. The impact energy to be performed on the specimen. 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. 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 anguol different body types to determine the most appropriate inertia.
El control del sistema frena el dispositivo una vez ejecutado el impacto. 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 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.
The tip of the impactor 11 anyulo an interchangeable tip that binds to the mass 7 by a threaded connection. The different positions can take the mass 7 increase system flexibility because different impact energies are achieved by moving the mass 7.
In relation to the arm and the mass, the mass is displaced and fixed along the arm as the impact energy needed.
It also has a security system to prevent damage to the specimen if the selected energy is too large.

Figures 3 and 4 show examples of system junction impacts on a test bench. EP EPA1 en The method followed for use is as follows: One kind of pendulum lever Huobujinsen Strain Rate Test device and method loading. Specifically, the impact device consists of a pendulum with a system of variable weights are placed anggulo different positions of the arm to provide greater flexibility to the system as to the impact energies that can be set.
From airplane wings, boats etc.
Thus it is achieved that the movement of both elements is integral. Figure 1 shows a perspective view of the embodiment of the ccharpy.
The prior art as represented several inventions, among which are the following: The angle of the surface on which is to impact measured with an inclinometer. By a push arm is released and impact run. The pneumatic system is lower consumption and a smaller electric braking system.

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