The Optimism Designing And Hydraulic Simulation On The Small Nonetrail Grab

For the sake of the small nonetrail grab have special advantages and widely application foreground,therefore,designing and improve the quality of small nonetrail grab has an important realistic sense.This paper is based on building system's model,then optimized its connecting rod system and built dummy model of mechanical-hydraulic system in the grab's arm. Furthermore,simulated and optimized the whole system.The main Work of this paper is as follows:Built the virtual prototypical model of the system and took locomotive simulation to it and protracted the bucket's locomotive track in one working cycle so get the working scale.Took careful calculation to the condition of grab and its loaded force and added corresponding load during different conditions,therefore,made the model much closer to the virtual circumstances.Through optimizing the structure of the connecting rod system to raise the force transmit ratio,then achieved the purpose of raising the excavated force.Through building the virtual prototypical model of hydraulic system and simulating confederate to mechanical-hydraulic system of the whole system.And do careful analysis,contraposed to the result of analysis,then optimized the corresponding parameters.The practice showed that it is available to put virtual prototypical technology apply to the optimism and simulation of the grab.I hoped that we can provide an efficient method and some efficient referential data to some relative project through this paper's description,especially hope using ADAMS/Hydraulics to build the model of hydraulic system can influence the extensive research.
