【Abstract】wWw.shuoshilunwen.com Along with the development of society, environment protection and energy sing,which he been risen to a political level in many countries, are attracting everyone’s attention. For example, our government has made clear in the eleventh five-year development guidelines the goal of conserving energy and reducing emission. Under this condition, pumping unit used in oil-field, which consumes a lot of energy are innovating for less energy consumption.By simulating the load simulator of beam-pumping unit, this acquires the data of pumping unit working under approximately actual conditions, which promotes the improvement of energy sing programme for beam-pumping unit.In this thesis, virtual manufacturing method is employed. It firstly establishes and assemblies the designed model, introduces the software of Adams in virtual environment to simulate for kinematics and kinetics, and checks the feasibility of the designed programme by using the experimented data.The main research contents are as follows:Firstly, it briefly analyzes the research background and present status and focuses on the polished rod load of pumping unit(including type and characteristics) and on its law of movement. Through simulating for kinematics by Adams, the Pumping unit’s movement has been understood more vividly. And through calculation by the software of matlab, pumping unit’s movement rules he been verified theoretically.Secondly, it construes the present load simulation programme and the advantages and disadvantages of their respective model, puts forward the improving plan. By comparison, it draws the final programme:load simulation being controlled by flywheel, magnetic powder clutch and magnetic powder brake.Thirdly, it designs and chooses the model according to the plan, including that of driver motor, magnetic powder clutch, magnetic powder brake, gear, axle, torque transducer and coupling, and builds the model needed for simulating in the three dimensional model Proe.Finally, it assemblies the simulating model in Proe, set the parameter by MECH/PRO, interface software of Proe and Adams, handling the data experimented by adding it to different places of the model on different time intervals in order to get the simulating data of the whole cycle, and obtain the more visual data needed for sing energy by analyzing the curve.Through the comparison between the experimented data and simulation results, it proves the rationality of the simulating programme. As a result, it can get simulating data from different working conditions. It is safe to say that the design of load simulator of pumping unit is much useful and practical. Because it provides data for the research and development of pumping unit’s energy sing control system and construct the foundation of conserving energy and reducing emission.
