Some examples of these machines are bogies for testing braking devices of railway wagon or battery bogies which facilitate the assembling and disassembling of the under-chassis components.

A fatigue test, to ensure long life of the materials in question requires high frequency equipment. A fatigue test of 109 cycles requires more than 7 months with a traditional test machine of 50 Hz. The same fatigue test takes only 19 days with a fatigue test system high-frequency 600Hz.

Our machines maintain a high-fidelity waveform while running at a high frequency. Depending on the requirements, we can provide systems with static load from 5 to1000 kN and standard waveforms (sine, ramp, square) or programmable block diagram.

The material test machines are a very versatile product that allows the characterization or the fatigue test in traction, compression or traction-compression of the parts that you want to test.

The system can be supplied with environmental chambers and used to determine the effects of temperature during the fatigue test.

Electromechanical type driven by a direct current motor or a brushless motor and with crank connecting rod mechanism, with adjustable stroke, which transforms the rotary motion into a sinusoidal one. By means of the potentiometer, the speed transducer and load cells, data for the characterization of the shock absorber are detected.

Hydraulic type with servo-controlled actuator suitable for high-speed levels (max 3 m/sec), which detects displacement, speed and load for the characterization of the shock absorber and creates files in Windows environment with diagrams of force-displacement, force-speed, sweep, force-temperature (applying a sensor in the shock absorber). Which can be used for fatigue tests with particular waveforms programmable in block diagrams.

We can build multi-station machines and machines with tilting mechanism to simulate the working position of the shock absorber.

To detect the chasse is provided a floating table which is equipped with two potentiometers allowing to detect the motion of the spring base in relation to its axis during compression. These machines can be also equipped with a lateral actuator that, by means of the floating table, detects the spring lateral flexibility.

Through data acquired is possible to perform files in Windows environment with diagrams characterizing the spring.

The trolleys where the leaf spring is placed are set for detecting the chord and the semi chords and they can be equipped with a transducer to detect the spring eye parallelism. It is possible to install a floating plan on the actuator to detect the planarity of the first leaf of the laminated spring. Inside the base of the machine there are automatic supports allowing the testing of the double layer laminated springs and springs with triple flexibility.

For leaf springs with exceeding height than the standard is possible to perform a Scrag procedure with self-learning to re-enter within the required parameters, which reduces the execution time.

We can supply machinery with robotized loading for production lines.

Our machines to perform TORSION TESTS are characterized by a rotating actuator (vane drive) servo controlled that applies a dynamic torsion load to testing component and by means of a torque meter and rotary potentiometer allows the detection thanks to the counter-reaction control of the force and the angular displacement.

These actuators are specifically designed for the test application. All components of the actuator are dimensioned to have a long life. All rotating parts are designed to be symmetrical to the axial center to allow an internal balance of the actuator itself. These balances allow use even at high speed and the use for fatigue tests.

Bench for Static Torsion Tests

For low-speed tests, we produce torsion machines driven by a stepper motor with a gear reducer. These machines are suitable for tests of batches production of rubber-metal components, the component to be tested is blocked by sealing jaws actuated by pneumatic pistons and then subjected to torsion with the torsional torque detection over the whole range of angular displacement programmed, it’s possible also set the speed of torsion. The parts to be discarded are marked and there is also a warning light and an acoustic message.

They also allow the measurement of accelerations in the point of application, because the moving actuator incorporates an accelerometer.

Moreover, if additional accelerometers are placed on the elements under test, then it is possible to obtain a study of vibration propagation (example: test in a railway carriage).

The pressers and the positioning devices can be transferred in suitable positions for each bogie, the position of each element is displayed on a monitor. For railway trucks equipped with oscillating girder with fifth wheel couplings very small, the portal allows to work with a single presser transferred to the center. To ensure the passage of locomotives or whole carriages the pressing portal can be realized with two movable girders.
