Abstract
Measured values obtained from a running test of an object to be tested and a module on a test bench such as a flat belt type chassis dynamo, and computation based upon numerical models of components other than the object to be tested and the module, are related to each other so as to reproduce a condition near to an actual running condition, for the object to be tested and the module so as to precisely analyze how the object to be tested and the module affects upon the motion of the overall vehicle during actual running of the vehicle. Thus it is possible to evaluate dynamic characteristics of respective vehicle components and a module which relate to the maneuvering performance of the vehicle, on a test bench in a condition in which a load variation and an alignment variation are taken into consideration.
