Abstract


Hydraulic excavators as an important class of engineering machinery, has been widely used in various construction field. The application of electronic control technology has become to improve the high energy consumption of hydraulic excavators, effective means of emissions and poor, as well as to further improve the efficiency and reliability of the hydraulic excavator. However, the manufacturing cycle of the hydraulic excavator, and the controller and system integration often to the link until late development, development of low efficiency and high cost. Papers on the basis of the analysis of the hydraulic excavator dynamics, to establish a real-time dynamic simulation model of the hydraulic excavator working device, and designed as the core controller dSPACE real-time simulation system real-time semi-physical simulation test platform for the reliable hardware and software test environment for the whole process of the development of the controller to improve the efficiency and safety of the controller development process, reduce costs and the labor intensity of the developer. Each chapter is divided as follows: The first chapter deals with simulation technology, especially the semi-physical simulation technology provides high fidelity simulation environment for the development of the hydraulic excavator controller, solve the controller long development cycle, the high cost of efficiency Low effective means. Chapter II of the overall program of the the hydraulic excavator half physical real-time simulation platform, focusing on the analysis of semi-physical simulation system for real-time hardware and software requirements, and dSPACE real-time simulation system as the core platform with 3D real-time display function design solutions. The third chapter analyzes the kinematic characteristics of the hydraulic excavator working device and establish the kinematic model of the three-dimensional space. The establishment of a solid model of the hydraulic excavator DirectX-based development environment to develop, on the basis of kinematic analysis, real-time display of three-dimensional movement of the hydraulic excavator platform. Chapter Chapter kinematic analysis based on study of the dynamic characteristics of the hydraulic excavator bodywork, and the establishment of a dynamic simulation model can be used for real-time simulation and simplified hydraulic system simulation model. Chapter kinetic parameters of the real-time model of the hydraulic excavator identification method, and to carry out experimental research. Parameter identification work on the basis of the trajectory planning comparative experiments, to verify the accuracy of the semi-physical simulation model and the effectiveness of real-time simulation system. The sixth chapter summarizes the main research work, and an outlook on future research direction.
