The Structure Analysis And Optimization On The Flex-plate

Car flex-plate is connected to the engine crankshaft and the car importancetransmission torque converter disk parts for automatic models. Disk drive connected tothe engine crankshaft and two automatic transmission torque converter transmissionparts, transfer torque to the torque converter, and also in the car driven by the electricmotor to start the crankshaft rotation. In operation, the disk drive is necessary to bear incars driven by the crankshaft torque converter drive plate acting on the car when helaunched the radial torque and motor driven radially outer ring gear torque generated. Inthe axial direction of the crankshaft and the torque converter axial movement of thedrive to save disk axial bending, disk drive torque transmission while absorbingdisplacement deviation of the crankshaft and the torque converter and alignment errors.The disc-shaped part and the high-speed rotation operation, the centrifugal force will becaused by inertia. Plate body type structural units farther away from the larger diskrotational inertia of the body center, in practice usually open at the outer edge of thedisk drive by lightening holes, on the one hand to reduce disk drive quality, on the otherhand to reduce the moment of inertia of the disk drive.In this paper, a certain type of car flex-plate static strength analysis of the variousconditions to obtain the stress, strain distribution; flex-plate mode and modal analysis;drive disc warping stability analysis; drive plate stiffness analysis; flex-plate fatigueanalysis; drive analyze the impact plate balancing openings. To ensure that the structureand size of the disk drive rational design, material selection properly, there is sufficientstrength, rigidity and stability is guaranteed. Get the flex-plate can work in a variety ofconditions and weld quality and weld length had a significant effect on the strength,stiffness and stability conditions disk drive web conclusions. These factors should be inproduction should be guaranteed.Topology optimization of continuum structures focused on a single objectivetopology optimization problems, however, there are a lot of multi-objective topologyoptimization problems in practical engineering structures, so only a single objectivetopology optimization is difficult to get to meet the actual needs of the project optimalstructure topology. This paper considers structural stiffness, strength, also calledstructure can have a greater moment of inertia, the smaller the mass, the use ofevolutionary structural optimization method for optimizing disk drive rotary member.
