Evaluation of new equipment for modal testing (English)
Abstract [en]

This report evaluates new equipment for model testing, and also the design of an EXE program created using Labview. The existing equipment was a Dytran 3032A accelerometer, a Dytran 5800A2 impulse hammer, two Dytran 4105C ampli˝ers, a Microstar Laboratories MSXB 042 quick-connect card, and one Microstar Laboratories iDSC 1816 data acquisition card, connected to a computer using the operating system Windows 2000 where the program Matlab 6.1 was used for data collection and Fourier transformation.A feasibility study was carried out with a National Instruments 9201 cDAQ data acquisition module mounted into a National Instruments 9174 cDAQ chassis using the existing impulse hammer and accelerometer, where a simple prgram in Labview 2014 was made.Given the price and compatibility with the existing impulse hammer, accelerometer and other systems within the laboratory, a National Instruments 9234 cDAQ data acquisition module installed in a National Instruments 9171 cDAQ chassis was selected, combined with a PC using the operating system Windows 7 and running an EXE application created in Labview 2014 and 2011 for data collection and Fourier transforming. The older equipment was left intact as far as possible as a reserve.

Abstract [sv]

Denna rapport går igenom utvärderingen av ny utrustning för modalprovning samt design av ett EXE-program skapat i Labview. Den be˝ntliga utrustningen var en Dytran 3032A accelerometer, en Dytran 5800A2 impulshammare, två Dytran 4105C förstärkare, en Microstar Laboratories MSXB 042 snabbanslutningskort, och en Microstar Laboratories iDSC 1816 datainsamlingskort, sammankopplat till en dator med operativsystemet Windows 2000, där programmet Matlab 6.1 användes för datainsamling och Fouriertransformering.En förstudie genomfördes med en National Instruments 9201 cDAQ datainsamlingsmodul isatt ett National Instruments 9174 cDAQ chassi, tillsammans med den be˝ntliga impulshammaren och accelerometern, där ett simpelt program i Labview 2014 togs fram.Med tanke på priset och kompatibiliteten med impulshammaren, accelerometer och övriga sy-stem inom laboratoriet, valdes en National Instuments 9234 cDAQ datainsamlingsmodul isatt ett National Instruments 9171 cDAQ chassi, tillsammans med en dator som andvänder opera-tivsystemet Windows 7, där ett EXE-program skapat i Labview 2014 och 2011 användes för datainsamling och Fouriertransformering. Den äldre utrustningen lämnades i största möjliga mån orörd som reserv.
