摘要
介绍新型液压支架用安全阀的结构特点和工作原理,采用功率键合图法对该阀组成的标准实验系统建立数学模型,编制仿真程序。结合实验和仿真结果,对影响该阀动态性能的相关因素进行分析,得出若干重要结论。
The structure characteristics and principle of the new type relief valve used on hydraulic supports were introduced. By using of bond graph, the mathematic model was founded. Combined the results of experi- ments, simulation and factors, which influence the capabilities of this new type valve, were analyzed and some important conclusions were educed.
