| Abstract: | In this paper mathematical models and dynamical characteristics of a load-sensing pump and a
load-sensing hydraulic system are presented. By means of numerical simulation and experimental re-
segrch, the range of suitable parameter values is given, with which the pump and the System can work
stably. Theoretical and experimental results show that the unstable problem is easily caused, when the
load-sensing pump is applied to the 1oad-sensing hydraulic system. An effective measure to solve this
unstable problem is Proposed. |
