【摘要】 为了全面分析水平定向钻的性能,针对不同领域,分别建立了机械、液压、强度和控制等子系统模型,通过参数关联形成了一个完整一致的水平定向钻整机虚拟样机模型。通过对模型的机械系统动力学性能、液压系统管路压力与流量以及关键部件的应力和应变仿真分析,为实际产品设计与优化提供了理论依据。更多还原

【Abstract】 In order to generally analyze the performance of the Horizontal Directional Drill(HDD),several subsystem models,e.g.mechanical subsystem model,hydraulic subsystem model,strength model and control subsystem model are built and integrated into a whole virtual HDD model through parameter associations.On this HDD model,the dynamic performance of mechanical subsystem,the pressure and flow of hydraulic subsystem and the strength of key parts are simulated and analyzed,these analysis results are used as basis for optimizing HDD product design practically.更多还原
