CAE Analyse And Optimization In Bonnet System Structure

Bonnet is important of the car body front. And its outer sharp is important to the result of the whole car sharp .Sharp and of the effects the result of the heavily.If the design of bonnet keep the quality of the total car can be checked by test . The bonnet test is include CAE analyzing test and the car test. The test result is one of the most important model of checking bonnet system quality and separate part quality。Becides,it is the most parameter to keep use and safety .Firstly design well, secondly test the car, then modify the design, that can keep excellent quality of the car.The bonnet weight control is important for the bonnet design. Relieve weight has something with the structure, so the relieve weight has to be checked by CAE test analyzing to keep stiffness of the bonnet system.According with the stand and the same class of car comparing result, the car bonnet is analyzed, then compared to the test result of the car, they are the same mostly. According with the comparing result, the designer has analyzed the separate partitions modification that can effect the quality of the bonnet.Then CAE test to the modification is good so that the quality of the bonnet is improved. The conclusion is that, second CAE comparing and analyzing the same class of car can modify the quality of the bonnet.. The text sets up the most parts maths model of the car bonnet.According with the result of the CAE analyzing, designer modifys and simply the parameters, checks and revises the part connection and concert, simulate craftwork situation of welding, connection and touching of the bonnet system Based on structure model, the designer analyzes and compare parameters of griddling plot, the material, the welding craftwork and touching situation. The designer tests the bonnet requirement by the unite CAE model, include retorting stiffness test, side stiffness, retorting stiffness test(middle restrict), gemel support...
