One, the flagship product that introductive RecurDyn software is Korea FunctionBay company, the much style that is new generation is kinetic emulation analysis software, it uses brand-new athletic equation to be mixed theoretically completely recursive and algorithmic, computation is stabilized quickly extremely, special agree with demand the much body system with massive solution kinetic problem, contact especially problem and flexible problem of knowledge of much style motivation. The function that RecurDyn provides a lot of convenience to use for the user (build model, figure like kind user interface, substantial function library, subsystem statified etc) , build a model quick, convenient, intuitionistic, accurate. RecurDyn software and software of of all kinds CAD/CAE and hydraulic pressure control software to wait to all have very good interface concern, and the its efficient efficiency that seek solution makes much software is emulated jointly solve massive problem and real time to emulate become a possibility. Because software is in,the theoretic advanced sex, good interface that build a model and interface concern, in obtain sufficient affirmation and self-identity domestic and internationally, apply extensively already at truck of equipment of machine of equipment of car of aerospace, military affairs, war, project, wiring, recreation, car, railroad, shipping at present mechanical etc is general the domain such as machinery. Use RecurDyn software, build a hydraulic pressure to disentomb mechanical " Zaxis200 " kinetic model. The model includes two pedrail system and chassis system, in considering frame and pedrail system annulus those who wear is flexible be out of shape. Emulate analysed the oscillatory case that has advanced to pit quickly, through with measure data actually to undertake comparative, the accuracy of the model gets effective test and verify. 2, the graph that build a model 1 frame and annulus worn FEM model normally, hydraulic pressure disentombs mechanical pedrail system does not have bedspring, damp like the car a kind pensile system. Be out of shape main concentration bearings in frame and pedrail system annulus frame on, because this accurate kinetic emulation analysis is,be necessary to consider their stretch metabolic. RecurDyn kinetic software is OK wait with MSC/NASTRAN, ANSYS, I-DEAS conveniently finite yuan of analytic software interface, will finite yuan of model in delivering RecurDyn software, come, build thereby contain flexible the system of mechanism of firm soft coupling of component. In this exemple flexible body is generated from inside MSC/NASTRAN (see a picture 1) . Pedrail system is like pedrail piece, bearing annulus, driving pulley for rigid body (see a picture 2) , all generate by software pattern plate, build a model very fast and effective. If other part matchs heavy, engine system, cockpit to wait with equivalent quality, inertia is replaced, use corresponding bedspring damper with the link of frame with imitate balata character. Graph 2 pedrail system 3, the test of wear of kinetic emulation analysis of advancing process is the standard item that every model must examine, its purpose is to inspect each component to fall to whether be put in life blemish in vibration and concussion action. Because road surface tries the cycle that check checks long, cost is extremely high, emulation analysis becomes very significant. But before undertaking component wear is analysed, we must first accurate get component to get the time process that carry, need accurate kinetic emulation analysis namely. However, to so complex kinetic system, the emulation analysis previously gives out hard satisfactory kinetic result, this makes wear function can decide through experiment ability only. To inspect RecurDyn crawler hydraulic pressure to disentomb mechanical kinetic emulation result analyses the feasibility that go up in wear, this exemple been quickeninging bank operating mode to the model (see a picture 3) concussion acceleration undertook emulation. Copy the result on time axis, can regard wear as the data of load time process of the test. Graph 3 overall model CNC Milling CNC Machining
