The Design And Simulation Research Of Watercourse Regulating Project Base-rock Detecting System

Watercourse base-rock detecting in the Yellow River flood is the key technology to solve problems, the research will lead to develop a new flexible, efficient, accurate, safe and convenient detection equipment, with non-contact detection technologies and machine, electricity, hydraulic control technology to improve the detecting technology level and the effectiveness of the plan, and protecting the people's lives and property security, and ensure the economic achievements in construction.On the basis analysis of the Jinan typical dam project of Yellow River, determine the overall design scheme of Watercourse regulating project base-rock detecting system. Servo control on luffing of base-rock detecting is the key research projects, only meet along the plane of uniform linear motion transducer to ensure accurate data detected reflects the distribution of underwater root. The optimal design of luffing mechanism and the static and dynamic characteristics of structure analysis for the box type telescopic jib is meeting the mechanical structure of watercourse base-rock detecting; Establish detection luffing simulation prototype and hydraulic control system transfer function model, using ADAMS software MATLAB, complete the seamless connection detection system servo control dynamic simulation and establish the correct mechanical prototype.Root of watercourse base-rock detecting system telescopic booms and luffing mechanism analysis toolbox of MATLAB optimization, cylinder and support hinge optimized design points. In luffing process of the hydraulic cylinder pressure and telescopic jib of dangerous section bending moment for target function, establish a three point hinge luffing mechanism, the mathematical model for optimal design of linear weighting method for constructing a multi-objective optimization problem of unified objective function. Through optimization analysis for the three hinge point luffing mechanism design optimization of parameters optimized luffing process, the maximum working pressure hydraulic cylinder and the dangerous section telescopic jib maximum bending moment value, improve mechanical structure design, meet to detect stone pillars of mechanical structure performance requirements.Detection system using Boolean mechanical model simplified structure, mechanical parts replaced by concentration rope to each day on flexible body, arm in arm and transformer oil cylinder add mobile constraint, cylinder and support hinge point, don't turn add constraint vice simulation results on parts of the movement of fixed constraint to simplify the prototype vice freedom and computation. ADAMS dynamics and kinematics simulation function simulation of detecting arm in power and external load movement, under the action of modified by simulation parameters for the design improvement prototype, establishing the correct mechanical joint simulation prototype. This paper build luffing cylinder and electrohydraulic servo valve flow model, through the transfer function of simultaneous equations of motion detection arm of the cylinder valve control are analyzed using MATLAB, the transfer function and build its dynamic characteristics of hydraulic control model of detection system. Joint simulation output state variables of the Measure sensor gain by ADAMS. Measure sensor based on range-finding sensors and Angle sensor set corresponding measuring precision and sampling period, the output of the arm length and Angle detection signal. Input state variables by MATLAB control model parameters Settings interface, mechanical and hydraulic control prototype model, model integration, setting simulation parameters of detection system based on simulation curve, joint simulation model of perfecting the hydraulic control, met the technical indicators and finally get the watercourse base-rock detecting system.
