2 One, Two, Four or Six - Test as Many Sock Absorbers as You Wis Rie comfort an safety are amongst te most important criteria wen it comes to selecting a car. Hig spees in particular make igest emans on moern vibration amper systems. Damper systems, McPerson struts an sock absorber systems use in moern axle esigns, often electronically controlle, are expose to extreme loas an tey ave to be capable of aapting teir amping properties to varying riving conitions witin millisecons. Depening on te esign criteria an veicle type concerne, sock absorbers may ave entirely ifferent caracteristics. IST as been eveloping servoyraulic sock absorber testing systems for aroun 30 years. MSP test macines are base on tis wealt of experience. Tey are conceive to analyse an assess accurately an reliably te material properties an caracteristic parameters of single-tube an twin-tube sock absorbers, river's cab ampers, seat an steering ampers an metallic impact absorbers. User-frienly application software running uner Winows enables input of all relevant parameters, customizing of analysis proceures an storage of test proceures an measurement ata. IST's MSP test system is terefore te ieal tool for reliable, fast an realistic tuning of veicle cassis esigns an evelopment of sock absorber systems. 2 Sock absorber test system

3 Learn more at: Benefits of te MSP System Moular Structure A moular system concept an an extensive range of accessories enable MSP test systems to aapt to virtually any sock absorber testing application. Hig Test Velocity A stury macine table accommoating te yrostatically supporte test actuator serves as seismic reaction mass. In conjunction wit te extremely stiff an robust macine frame, igest test velocities can be acieve. Optimum Damping Caracteristics Viscoelastic spring amping elements optimally cusion te sock type vibrations generate by te test system, meaning tat no special founation is require. Protective enclosure Higest Operational Reliability Te amply imensione, yrostatically supporte piston ro is not only capable of witstaning te sie loas commonly occurring uring sock absorber testing, but also provies te macine wit extraorinary reliability. Future-Oriente Te DampPro software meets all relevant stanars an specifications of te automotive inustry, an can be upgrae wit aitional moules in accorance wit te requirements in an. Hig Resolution of Measurement Results Wit its ig ata acquisition rate of 5 khz per cannel an its 19 bit resolution, te Labtronic 8800 igital measurement an control system guarantees accurate results even wit igest test velocities. Simple an Safe Operation Simple an safe operation was one of te most important criteria in te evelopment of te DampPro software, so as to enable complex testing tasks to be anle wit a maximum of operating convenience. Iniviual DampPro moules can be combine arbitrarily into a complex, automatically execute test sequence. Maximum Safety Te MSP system is equippe wit state-of-teart safety evices, an at te same time offers igest operating convenience uring macine set-up. Te basic configuration of te MSP macine inclues a protective enclosure wit a oor monitore by safety switces. Wile te oor is open, te macine operates in te loa protect moe wit reuce oil pressure an oil flow. Applications Depening on te MSP configuration cosen, te following typical test proceures in te area of sock absorber testing can be performe: Damper Stroke Determines te amper stroke. Taring Determines friction an gas force at low velocity. Caracterization Determines te amper force as a function of velocity. Valve Testing Determines te service life of te bottom an piston valves. Fae Test Determines amper properties as a function of amper temperature. Hig Velocity Test Recors an assesses te caracteristic curve at ig piston velocities. Replay Test Reprouces measure time istories. Testing of CCD Dampers Determines amper properties as a function of valve rive. Enurance Test Determines amper properties after extene service. Sie Loaing Determines amper properties uner sie loas. 3

4 Accessories for Your Applications A wie range of accessories enables te MSP system to be tailore even to igly specific requirements. You will be able to benefit from IST's long-staning experience in te area of sock absorber testing. Be it special-purpose mecanical grips, temperature equipment or sie loa input - te MSP system is extremely flexible an can be customize to your particular requirements. Many oter testing applications not feature on tese pages ave alreay been realize by IST. Our specialists will be please to consult you. Testing of four sock absorbers wit temperature measurement an air cooling equipment Mecanical Grips Mecanical fixture for clamping a amper at te swivel eyes. A treae aapter is available for ampers wit treae attacment. Temperature Control Te system inclues one temperature sensor wit 2-point control per sock absorber. Te temperature sensors measure actual specimen temperature an transmit tis information to te temperature monitoring system (temperature controller). Te DampPro software enables temperature limits to be set an te esire action to be efine. Temperature Camber For irect eating of te ampers. Scope of supply inclues pull ros an frame attacment. Working temperature range from -40ºC to +200ºC. Specimen grips Temperature camber 4

5 Sie Loa System To introuce sie loas at te top bearing of te amper. Air-Cooling An air-cooling system avois overeating of te ampers. Te system is controlle by te DampPro software as a function of temperature. Cooling cycles are run if necessary. Sie loa input for six ampers Accumulator System In case of ig velocities te accumulator system covers te oil eman for a limite number of strokes. Sie loa input into a single amper Sie loa input into four ampers. System inclues air cooling Accumulator system MSP test system for testing six sock absorbers 5

6 Software DampPro Powerful an Easy-to-Use Te DampPro software was evelope on te basis of te stanars an test specifications of te automotive inustry wit a view to proviing maximum ease of operation. DampPro controls te entire test proceure, incluing ata acquisition, analysis an final presentation in a test report. Wit DampPro, new complex tests can be set up easily an save for subsequent re-use. Suc a test proceure migt look, for example, as follows: Friction test wit etermination of gas force Determination of te amper force at various velocities Enurance test Tis sequence can be repeate several times. Report Trougout te test proceure, DampPro monitors temperature, initiates air-cooling an conucts cooling cycles if necessary. DampPro's integral report generator enables customize test reports to be create. Apart from amper force versus velocity plots or force-isplacement ysteresis loops, customer-specific illustrations or corporate logos can be inclue in te report. PlayDat - Test efinition 6
