Research Of Rollover Of Monocoque Coach

At present, the upper for coach safety study is less, and there are lots of problems forthe calculation results. Based on a company's a11meters long bus, rollover on coach aredescribed in detail, and put forward a series of innovations, played an important role inguiding the design of coach, have certain reference significance for coach designcompany.This article refer to the ?GB17578-2013coach strength requirements and testmethods for the upper structure?, based on finite element theory and the characteristics ofthe coach, has carried on the simulation to the coach.First, describes the general situationof the study of domestic lateral double, and points out the shortcomings of the presentstudy. Second, simply introduction of the rollover safety standards. Third, the use of finiteelement theory and the software is introduced. Fourth, described by the CAD model intothe process of CAE software and CAE model of geometric correction, the boundaryconditions of CAE model is put forward innovative also speed up the computationefficiency of method. Fifth, the analysis of the various parameters, the result of theanalysis and innovative quantitative living space invasion, this paper presents the method.Sixth, unreasonable structure puts forward the improvement scheme of coach, theoptimized results and verifies the correctness of the results.
