An Analog Model of a Powerplant Coupled to a Real Car for Structure Dynamic Development 680147

This paper presents a method of evaluating the powerplant’s influence in the dynamic response of the car structure. The technique involves an analog computer simulation of the powerplant and its mounting system, which runs in real time, and is interfaced to the physical car through position transducers and electrodynamic exciters at the engine mount locations. This allows an accelerated evaluation of many engine-transmission combinations, with a wide range of mount parameters, on a single car structure.
