A recent Siemens Simcenter blogpost discuses test-calibration of mode shapes. The test set-up includes Qsources Q-ISH integral shaker on the SimRod, a full electric sportscar at Siemens Simcenter. Control of the mode shapes allows modifications to increasing the range of a vehicle and optimizing the drivetrain.
Next to CAE based modal analysis the actual testing supports a balanced development. However, testing can become expensive. The example of the Simcenter Qsources Q-ISH integral shaker shows that excitation and calculation can be performed in an easy and fast manner. The compact shaker can be attached and positioned easily under any inclination and has a patent protected self-aligning stinger-suspension system. This way the shaker can be mounted directly on the relevant excitation location.
