It provides excellent properties for low frequency excitation of such devices. Furthermore it is opti-mized for measuring decay rates in very lightly damped structures.ApplicationsCalibration and test for seismic instrumentsSeismic simulation for componentsDetermination of natural mode frequencies,shapes, damping ratios, and stress distributionsFeaturesDesigned for calibration and evaluation ofaccelerometersCan be used to generate sine wave, swept sinewave, random or impulse force waveforms, fullyadjustable at sourceOptimized to deliver power to very lightly dampedstructures with minimum shaker weight and drivepowerAdjustable armature re-centering for horizontaland vertical operation or other external pre-loadsRugged standard armature and air bearingguidance systemOne-Man Portability - 36 kg (80 Ib) total weight日本代理店 : エフ・アイ・ティー・パシフィック株式会社東京都台東区浅草橋3-20-15　浅草橋ミハマビル4FTel : 03-5820-7021　Mail : asdummy@fitpacific.com

In addition an airdistribution system, tie down and leveling base areprovided.The near zero friction of the air bushings is anessential feature for measuring resonance decayrates in very lightly damped structures.The unit employs a permanent magnet and isconfigured such that the armature coil remains in auniform magnetic field over the entire stroke range.This feature, along with the air bearings, assures ahigh degree of force linearity and absence ofarmature guidance induced noise and distortion.Drive power for the shaker is obtained from a lowfrequency power amplifier, such as the APS 125 -Power Amplifier.Modes of operation requiring high bearing loads(table mode and APS 0112 - Reaction Mass mode),permissible with the standard linear ball bushingversion, are not permitted with the APS 113-ABshaker. Since the suspension system need notsupport the armature and test load weight whenused in the horizontal mode, a soft suspension maybe used, minimizing non-linearity effects. Themaximum overhung load that may be used is 1.5 kg(3.3 lb) concentrated at the mounting point.The shaker may be used with various optionalaccessory items to extend the areas of application:APS 0108 - CARRYING HANDLES AND TIE-DOWN BARS - improve the portability feature ofthe shaker.APS 0109 - ZERO POSITION CONTROLLER -automatically controls the zero position of avibration exciter irrespective of its load.APS 0162 - VERTICAL MOUNTING KIT - permitsvertical orientation of the shaker, either free-standing or rigid bench attachment.Optional ConfigurationsAPS 113-AB-HFAll features of the basic APS 113-AB shaker areretained. The drive coil is made for 40 % increasein force with a 50 % duty cycle (30 min cycle).PerformanceAcceleration performance of the APS 113-ABshaker with various mass loads is shown in thelower graph.1101000,1 1 10 100ACCELERATION-m/s²FREQUENCY - HzACCELERATION WITH VARIOUS MASS LOADSAPS 113-ABAPS 113-AB-HFNO LOAD1 kg (2,2lb)1,5 kg (3,3lb)Rev. 2010-11-06APS 113-AB with APS 0162Vertical Mounting Kit
