Abstract: Parallel hybrid excavator technology has been successfully developed and showed good energy saving effect. Especially, it plays an important role for the life extension of the engine and the im-provement of fuel efficiency. However, its power systems were composed by diesel engine, electric motor and pump coaxially. Although it can save installation space by this link style, it may cause a strong electromechanical coupling, and even severe shafting vibration and noise. Eventually, it may affect spindle life and driving experience. Based on the analysis of the parallel hybrid vibration coupling mechanism, a new strategy based on hardware and software optimization was put forwarded. The experiment results show that it could reduce shaft vibration and improve the driving condition.
