<strong>TIRA</strong> WPM LeipzigServo-hydraulic testing machinesFried and tested servo-hydraulic from Leipzig:Servo-hydraulic test machines are used in a wide range of materialand components testing. <strong>TIRA</strong> WPM Leipzig offers a modularbuilt program of servo-hydraulic test machines and operatorspecified produced single and multi-channel systems.Servo-hydraulic test machines configurate in an unit-assemblysystem and can be offered to your individual requirements.Different sizes and types of frames and clamping tools for tensile,compression and bending tests as well as special holder forexample for fracture mechanic tests are available.The most important characters of the new generation ofservo-hydraulic test machines are:• Digital-modular measuring and control electronics based on amulti-processor system• user-friendly Windows-operating surface• develloped test cylinder serie with clearly improved dynamicsand working safety• hydraulic power packs with modern technical solutions whichfullfil all requirements for a reliable and effective use of servohydrualictest systems• switch-on and switch-off equipments for single and multichannelsystemstest unit for air craft bodies standard bodyTHE CLOSED ELECTRO-HYDRAULICCONTROL CIRCUITThe extremely precise control of static and dynamic load for thetest parameters force, path, elongation or an external formedvalue is granted by the closed electro-hydraulic control circuit.The required course of the test can be specified by a set-point signalwhich is generated in the control (sinus, triangle, rectangle)or external entered. A corrective signal is formed in the variablegain amplifier by the difference between the set-point signal andthe true value force, elongation or external values and suppliedto the servo valve for equalization of the deviation. The oil flowwhich drives from the hydraulic power pack to the test cylinder isthen controlled by the servo valve. The specified test procedure ismade with high dynamic and precision.test system for slide bearing (drive 6000 U/min)12

<strong>TIRA</strong> WPM LeipzigMEASURING AND CONTROL DEVICESThe requirement for an optimal use of servo hydraulic test systemsis a productive and job specific process control. You gain of thewide experience in the field of measuring and control methodwith test systems from <strong>TIRA</strong> WPM Leipzig - especially for highqualitytest assignment.The control of the servo hydraulic is based on a two-computersystem.One of the computer is responsible for the measured-dataacquisition, the control as well as the set-point value. The secondcomputer functions as an input unit and control unit for the operator.It is also used for the data processing and data visualisation.The control software works under the operating system MSWindows 2000/NT.Our control distinguishes by the following features:• measuring and control method for single and multi-channelsystem, modular in a 19"-box system• fast 16-Bit-data acquisition• triggering of the servo-hydraulic test cylinder• adjustment of the parameters force, path, elongation and andPID-variable gain amplification through the computer - alsoduring the test directly by the operator software• adapted peak value control• creation of one-level and unit programs as well as of operationalload - reproducible test procedure• interface to the signal optimization of reproducible test procedure• control of limit value of the measured quantities, emergencystopfunction,signal exchange with the hydraulic power packcontroller for servo-hydraulic systemsCONTROL AND EVALUATION SOFTWARE FORTHE SERVO HYDRAULIC CONTROL SYSTEMThe operation of servo-hydraulic test axis in single and multi-channelsystem is made by a user-friendly software packet underWindows. This workflow grew by and with the requirements ofthe user.You have a wide software product at your disposal with which awide spectrum of test parameters for material testing and componenttesting.servo cylinder 100 kN with hydrostatiic bearing14
<strong>TIRA</strong> WPM LeipzigCONNECT. & BREAKING MODULE FOR SERVO AXISThe safe connection and disconnection of single or mulitchannelservo axis are done by connecting modules. We offer them in twonominal values with each up to 4 channels.RELIABLE HYDRAULIC POWER PACKA proven serie of hydraulic power packs in the power stage from10 up to 320 l/min supply the testing machines and stations withhydraulic oil at an operating pressure which is factory-providedadjustable between 80 and 280 bar. With that a later integrationinto existing servo hydraulic stystems is possible.16
