Design of Triaxial Platform Used on Automobile Parts’ Testing

A type of triaxial platform which can apply X, Y, and Z three direction load forces simultaneously to the testing specimen is introduced. It can be used for kinds of automobile parts’ testing, such as intermediate bearing of drive shaft (IBDS), engine suspension cushion, connection rod, and control arm bushing. All these parts have two connection ends, one of which can move in at least three directions relative to the other. The kinematical characteristic and kinetic performance of this platform are analyzed. An example of the triaxial platform used on IBDS is introduced.
