Abstract


The modern logistics engineering applications with a large number of machinery and equipment, which is mainly used for all kinds of material handling reproduced job has a very important role in lifting machinery. Order and let the material, various types of lifting machinery must be equipped with grab, clamp, sling extract device, so the correct and rational design of these devices to improve the the lifting machinery operating efficiency, reduce human labor intensity and ensure personal safety. plays a crucial role. To accurately analyze the dynamic performance of the lifting machinery, the experiment is the most effective and direct way, it can actually measure lifting the mechanical bear the load and structure stress. Lifting machinery measured only after the completion of the production of the product may be achieved, doing risk, high-cost, long life cycle. The kinetic analysis of the general computer way, the use of finite element analysis software, multi-body dynamics analysis software tools such as auxiliary to achieve better dynamics analysis software is on ADAMS. However the ADAMS software data storage and comes solver in the analysis of complex prototype model appeared to be inadequate. Professional control software Simulink software as a MATLAB toolbox can be good on a variety of dynamic systems for real-time simulation MATLAB calculus algorithm can also be used to quickly and accurately solving calculus equations reduce calculation time and calculation errors. In this paper, the virtual prototyping software ADAMS grab hoisting system combine to carry out dynamic simulation of technical analysis and dynamic simulation software MATLAB / Simulink mechatronics dynamics simulation technology, completed liter grab from the system dynamic analysis of the kinematics and dynamics of mechanical simulation sports results, and then come. Grab cranes by understanding the trends at home and abroad crane dynamic characteristics of the status quo, this paper analyzes the necessity and feasibility of the the joint mechatronics simulation technology in the the crane dynamics in the field of research and analysis application, and the combined simulation analysis grab from the liter system dynamics, the main work is as follows: 1, including wire rope model grab from the CAD model of the lifting system and virtual prototype model, the car, grab the rope as a system simulation at different operating conditions to simulate the The dynamic characteristics of various operating conditions. This is elaborated in the literature of the past no. 2, a ADAMS and Simulink joint to mechatronic simulation method to solve the problem of the ADAMS simulation error in solving complex model. In addition to using ADAMS macro commands to achieve fast virtual prototype model of a complex system. 3 discusses the mathematical model of the the YZR-315M three-phase asynchronous motors, control block diagram and simulation models, and simulation in Simulink its electrical characteristics. 4, the use of co-simulation method, grab, hoisting mechanism, opening and closing mechanism, trolley system dynamics analysis obtained grab hoisting system dynamics, for grab crane dynamics design basis.
