The development of structures and individual components is based on computational life estimation. This is to ensure that the products remain fail-safe within their calculated service life. However, the verification of the computational life estimation is carried out through laboratory testing with realistic simulation of service conditions including displacements, loads and environment.
It is necessary to introduce service loads in a controlled way into materials, components or system modules. The actuators required for this purposes must meet the highest requirements for precision and controllability in order to produce reliable results. Furthermore, these actuators have to be robust and able to operate in a reliable way over many years of operation.
Solution
Hydropuls® linear and rotary actuators convert hydraulic energy into displacements and forces at the test specimen. The actuators are controlled precisely by the 8800ml control electronics and the servo-valve. Hydropuls® actuators can be used in static and dynamic test applications from single axis test machines through to multi-channel test systems.
Hydropuls® actuators are characterized by a number of unique attributes that ensure precise and highly productive operation.
The hydrostatic bearings and the non-contact sealing of the piston rod are unique to the Hydropuls actuator range. As a result, the cylinders are hysteresis-free in quasi-static and dynamic operation over the full displacement and force range. That is free of mechanical seals, friction and wear.
