南昌航空大学科技学院学士学位论文Simulation of its Hydraulic SystemStudent name:Fu Hao MinClass:078105207Supervisor:Xing PuAbstract:The truck mixer is a vehicle for transportation concrete.It is fulfilledtwo actions,conveying concrete and mixing concrete.These actions not only ensurethe quality of the concrete,but also make the conveying distance longer.But in thenorthwest area of our country,research on the field of the truck mixer is little.So thetruck mixer must be developed strongly in order to meet the need of the risingconcrete market.Three important parts are studied in this thesis.Firstly,thehelix-vanes of the truck mixer are designed following the principles of the flowingstate of the concrete on the helix-vane.Secondly,the drum of the truck mixer isdesigned base on its working characteristic.Thirdly,with the widely used soft warepackage SIMULINK the mathematic models of the hydraulic system driving thetruck mixer are established on the found of the theory and method of power bondgraph.The dynamic characteristics of the hydraulic system are simulated numerically,and some significant results are presented.Key words:Truck MixerDrumSpreadHydraulic SystemMathematic ModelsStructure DesignHelix-vanesPower Bond GraphDynamic CharacteristicsSimulationSignature of Supervisor:目录
