Finite Element Analysis Of The Planetary Gear Of A New Type Of Dual Clutch Transmission (DCT)

In this paper, the planetary gears’ designing of a new type of Dual ClutchTransmission (DCT) is the research object. Static and dynamic contact analysis ofgear pair are implemented using finite element analysis software ANSYS. Andthen check the gear′s dynamic contact stress using dynamic analysis softwareANSYS/LS_DYNA.Realized parameterized modeling of involute gear with large three-dimensional modeling software Pro/E. Making use of parameterized modelingmodule of software Pro/E, obtain different gear model of distinct parameters afterinputting different gear basic parameters in the parameters input dialog box,basic on already modeling gear model, and this improve the efficiency of gearmodeling.By the excellent data exchange interface between Pro/E and ANSYS, theengagement gear model is imported into ANSYS and then is transferred into finiteelement model by meshing. Static contact analysis of contact stress and bendingstressis executed taking friction into account by using the full Newton-Raphsoniterative algorithm on sun gear and planetary gear pair. The maximum bendingstress of planetary exceeds the materials allowed value in the static contactanalysis, after optimizing of gear′s parameters, the new engagement gear complywith the design and material requirements, indicating that the finite elementanalysis of the contact model is able to get the value of static stress.Dynamic contact analysis of gear pair is executed using multi-body dynamicanalysis methods to define rigid body and rotation unit. The results show thatoptimized sun gear and planetary gear pair is comply with the design and materialrequirements using dynamic stress analysis, which verifies the correctness ofparameters of the new engagement gear.
