Abstract:
A system for determining dynamic properties of a chassis component includes a first fixture, a second fixture spaced from the first fixture, and a chassis component arranged between the first and second fixtures. The chassis component has a first end arranged at the first fixture and a second end arranged at the second fixture. A shaker system is arranged at the first end of the chassis component. A first multi-axis force transducer is arranged between the shaker system and the chassis component. The first multi-axis force transducer includes at least a 3 degree of freedom (DOF) sensing capability. A second multi-axis force transducer is arranged between the second end of the chassis component and the second fixture. The second multi-axis force transducer includes at least a 3 degree of freedom (DOF) sensing capability. A controller is coupled to the shaker system, and the first and second multi-axis dynamic force transducers.
