Pipeline characteristics have impact on stability of hydraulic poppet valve. Sub-lumped parameter collective model of pipeline is established based on power bond graph method in order to explore the impact of the pipeline characteristics on the hydraulic poppet valve vibration. The impact of pipeline characteristics on vibration characteristics of hydraulic poppet valve was analyzed with simulation based on Simulink simulation platform. The results show that: Overall, the pipeline characteristics can suppress low-frequency vibration and promote high-frequency vibration; when the pipeline length is large or diameter is small, hydraulic poppet valve tends to occur high-frequency vibration; when the pipeline length is small, hydraulic poppet valve tends to occur low-frequency vibration; when the pipeline diameter is big, hydraulic poppet valve stability is significantly enhanced.
