Investigation Into Road Simulation Experiment of Powertrain and Its Key Components of a Fuel Cell Passenger Car

An elementary but integrated experiment is described,including the real road load sample on proving ground,road load reproduction on vibration test rig,total vehicle road simulation test and key components vibration tests.Remote parameter control technology is adopted to reproduce the real road load on 4 poster road simulator and six-degree-of-freedom vibration table which are used respectively for total vehicle and components vibration tests.After the total vehicle vibration test,vehicle driving performance and fuel economy are regularly measured on chassis dynamometer to validate powertrain system degradation resulting from vibration.The fuel economy was found to have decreased by 17.59% and structural damage of vehicle body structure and components were observed in the evaluation of structure strength and operation malfunction of powertrain system.The systematic experiment process and validation method helped to improve the durability,reliability and life of fuel cell vehicle,powertrain and its key components.
