凿岩机冲击压力先导控制油路性能研究
|
摘要
凿岩机液压控制系统需根据推进和回转负载情况自动调整冲击回路的压力参数,以实现凿岩机多个运动部件间的压力流量精确匹配,从而实现高效凿岩和防空打功能。根据凿岩机冲击压力控制原理,结合实验数据建立了系统的非线性数学模型,利用方框图方法分析了先导控制回路的动态特性,找到了先导压力控制系统中结构参数、介质流动特性参数对系统工作性能的影响规律,为凿岩台车类产品开发提供参考。
The drifter drill hydraulic control system needs to adjust the pressure parameters automatically under thrust and rotation conditions to match the pressure and flow between multi-actuators, achieving efficient drilling performance and avoiding free hammering.According to the percussion pressure control principle of this hydraulic drifter, a nolinear mathematic model, which arguments were identified by the experimental data, was set up for this hydraulic control system.This mathematic model illustrated by block diagram method was used to investigate the dynamic performance of the percussion pressure pilot control system. The laws that structural and fluid flowing parameters affected the working performance of this hydraulic system were obtained, providing reference for drill rig product development.
