| Abstract: | The working principle of the full hydraulic drive system was described,and a new full hydraulic drive system featuring the application of a new secondary regulation component,hydraulic transformer(HT),and a hydraulic accumulator was constructed for the walking and working systems of a minitype loader.A mathematical model was built for the pressure transforming ratio of the HT,and also a mathematical model for the accumulator.The relationship of the characteristic parameters versus the HT port plat control a... |
