In general, most electric vehicle manufacturers make cars using monocoque bodies. This type has advantages such as low production cost, light weight and good fuel economy. However, it is not suitable for small-series car manufacturers because the design is very difficult and requires investment in large production processes. In this study, the bending stiffness and torsional stiffness of a composite material (CFRP) frame that can be applied to various small-series vehicles with one platform were measured and analyzed.

In this study, we developed full vehicle model for vehicle dynamics simulation based on IPG CarMaker. Suspension components(spring and damper) characteristics test data apply using hydraulic actuator. Vehicle model K&C(Kinematic & Compliance) characteristics data apply using SPMD(Suspension Parameter Measurement Device). Vehicle handling dynamics test data measurement get using vehicle CAN, GPS/INS, WFT(Wheel Force Transducers). Finally, we compare developed virtual model simulation and vehicle handling dynamics test for model correlation analysis.
