| Abstract: | To study dynamic characteristics of a powered support hydraulic system and its effect on action of a powered support, a dynamic model of hydraulic system is established by means of power bond graph. A simulation program is designed. The working process and relevant properties of the system are simulated by the program. The conclusions of the study can be used as guidelines for design of the system and for improvement of characteristics. This study provides an effective method for evaluation and improvement of a powered support hydraulic system. |
