This angle can be any: Wind tunnel test method to study out-of-service tower crane behaviour in storm winds. Mediante un pulsador se libera el brazo y se ejecuta el impacto. By a push arm is released and impact run. 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. Patent ES in which a pendulum xharpy testing having a modular ve, 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.
Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. The prior art as represented several inventions, among which are the following: Figure 1 shows a perspective view of the anguo of the invention. In Figures 3 a practical embodiment of the invention is shown wherein the device anchor in one of the columns of a portico.
Also on the axis of rotation 3 the arm 6 ending in a mass 7 constituting all the agnulo is fixed. The flexibility in use, with easy adaptation to different places set, to be a portable device. Impact pendulum-type testing machine for testing samples of materials with repeated impacts.
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. It also has a security system to prevent damage to the specimen if the selected energy is too large. The method char;y for use is as follows: The advantages of the device of the invention are: The tip of the impactor 11 is an sngulo tip that binds to the mass 7 by a threaded connection.
The brake comprises two brake discs attached to the shaft and two pneumatic grippers. fharpy
Braking system control device once executed the impact. To solve this and other problems has developed the pendulum impactor of the invention.
The hammer is intrumentalizado and the device has a data acquisition system.
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. Said device is provided with a braking system which controls the height of angulk impact once defined the energy ed with which will impact and similarly this braking system avoids rebound anguko impact. The utility model has a Charpy pendulum whose main characteristic is the support plate which actuators pendulum support.
It is an object of the invention to establish different test parameters depending on the type of material and the notch chxrpy 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.
The device is compact and versatile and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction. EP EPA1 en 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.
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.
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.
ES2473666B1 – Pendulum device for testing low energy impact – Google Patents
The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. Sobre la masa va atornillada la entalla: ES Kind code of ref document: Charrpy different positions can take the mass 7 increase system flexibility because different impact energies are achieved by moving the mass 7.
Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed. The dough is firmly joined to the arm via a connecting bolt passing through both.

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. One kind of pendulum lever Huobujinsen Strain Rate Test device and method loading. Esta es una de las This is one of the.
