Click to View	Response Spectrum Analysis of a Process Control Valve A process control valve assembly was studied by Badger Meter, Inc. The engineer performed modal and response spectrum analyses to determine the stresses induced by earthquake vibrations.
Click to View	Frequency Response Analysis of a Turbine Compressor Blade Test Hamler Test and Analysis used modal and frequency response analyses to optimize the testing of a weighted turbine compressor blade.  ALGOR FEA software was used to predict the proper size and location of each weight.  In this way, trial shaker experiments and the fabrication of trial weight assemblies were both minimized.  The frequency response results for the first, torsional vibration mode are shown here.
Click to View	Frequency Response Analysis of a Compressor and Motor Base Tolpa Technical Services constructed this beam and plate element model of a compressor and motor base. Natural frequencies were determined and a frequency response analysis was run to determine the effects of vibration forces induced by the compressor.
	Shock Analysis of a Sterngate Hydraulic Power Unit To reduce the expense of shock tests, Huber, Inc. verified the structural integrity of this hydraulic power unit using the Dynamic Design Analysis Method, sometimes referred to as "DDAM" (Dee-Dam). The power unit operates the sterngate on a USS San Antonio Class amphibious assault warship.	56K   100K 250K
