Deviation Correction Control of Full-hydraulic Direct-push Sampling Rig
摘要
Abstract
Environmental pollution site investigation and risk assessment are particularly important for land security.Currently,full-hydraulic direct-push sampling rig is applied widely in sampling operations.The drill tool is rigidly connected to the integrated frame and vehicle body.So the deviation of integrated frame and vehicle body will cause the deviation of drilling direction.In order to ensure initial direction of drill tool and realize deviation correction control of integrated frame and vehicle body,a deviation correction control strategy based on triaxial tilt angle is proposed.Concurrently,we establish models of each system and simulate under different initial conditions.The simulation results show that the control strategy has excellent control performance,high leveling accuracy,and single-direction adjustment time is not exceeding 6 s,which is suitable for full-hydraulic direct-push sampling rig.关键词
