The Application Of Spring Back Simulation On The Manufacture Of Press Girder

Along with hurtle to press to take shape the finite elasticity theory booming development that imitates the true research, with finite element modelling for core of take shape the number to imitate the true technique to be gradually maturing, provided the new path for the essence regulation that the people know that the takes shape the process, in order to carried out the virtual manufacturing that takes shape the realm to provide the powerful technique support, this make the limited imitate the true analysis in the automobile industry of application be subjected to the value increasingly.Passing to take shape to imitate true analysis can at face the molding tool business enterprise to provide the powerful support in many ways:At design the possibility of the earlier period stage evaluation molding tool design, craft complement of the work;At try to hurtle to try the mold stage to carry on breaking down the analysis, solve problem;Produce the stage to used for the blemish analysis in the batch quantity, the improvement spare parts produces the quantity, can use to adjust the material grade at the same time, decline low cost.A number imitates the true technique to develop to design the extensive application in the molding tool, developping the change of the process to produce the profound influence to the traditional molding tool.Returning to play problem is the widespread problem that the molding tool usually meets in the development, the creation that returns to play will affect the end shape of the spare parts directly, make the accuracy of the spare parts under the influence of affect, then the assemble of the spare parts, acquired the qualified spare parts in the past my companies all are at adjust try stage pass to molding tool change, waste a great deal of manpower financial power, and wasted a great deal of time, can't make the contract period guarantee.At design the stage to pass to return to the estimate for play, measure and the repair can ease to adjust to try the workload in the process consumedly, decline low cost, shorten the product development period, at criticize the production stage, improvement the spare parts accuracy exaltation assembles the quantity.Particularly for return to influence of play the bigger beam piece is obvious.This text aims at to hurtle to press the emulation calculation that the beam research returns to play and lower back to play the method to the work piece several the accuracy the influence, and said the lamella to hurtle to press to return to the creation mechanism for play all on this foundation, a number imitates the technical and related and basic theories, analyzing the influence to return to main factor of play the number.For the emulation that return to play, want to carry on the emulation that hurtles to press to model first, in modeling to imitate the foundation for pass, then carry on the work piece analysis that returns to play.Aim at to return to play the phenomenon existently, pass the variety that the variety of model the parameter returns to play after come analyze to model gradually first, if return to play and can't still satisfy the quantity request of the spare parts, must adopt back to play the repair, and aim at back to play the in expiation of form, analyzing the size of thecertain in expiation of quantity, passing the contrast toward the end in expiation of quantity and the product parameter analysis, making sure the in expiation of parameter.Make use of the repair parameter carries on the product model to change, and get the end emulation result.Compensate the model of empress to carry on the processed spare parts to carry on the diagraph towards make use of, carry on examination result and imitate analytical as a result contrast, judge to imitate the analytical ccuracy of result.The article got some main influence factors and regulations that return to play, returning to play to provide the valid path for the reasonable repair, and for overcome the molding tool development process in of return and play the problem drew up to provide the guidebook and references.This text work to later the new car type of the development hurtles to press the piece to overcome back to play to raise the product quantity contain important meaning.Before pass expect of the CAE analysis repair return to method of play the Cape, the molding tool adjusted to try the period to shorten the half as about five days, and avoided two number of timeses control and other some workloads, economized a great deal of manpower, material resources, financial power.Lower the molding tool cost consumedly.
