Abstract


The frame is important bearing member in the car frame under various load vehicles pass . Therefore , the performance quality of the frame structure directly affect the quality of vehicle design or not. At the same time , the performance of the car with the rapid development of the automobile industry is becoming more and more high , which makes traditional design calculation method has been unable to meet the requirements of modern automotive design . The emergence of the computer , especially the large computer as well as the rapid development of the finite element method for the frame structure of the performance of various analysis brings new changes . Frame structure , finite element analysis , the use of the analysis to optimize frame the parameters to improve vehicle performance and reduce design and manufacturing costs , so that the corresponding models occupy a dominant position in the market and so has a very important significance. It is in this context that the finite element method as a basic technology means to the general-purpose finite element analysis software ANSYS as a platform for computation, analysis , basic mechanical properties of Hubei Tri-ring Special Vehicle Co., Ltd Model trucks frame forecasting and modeling , and to optimize the design of the frame . Appropriate simplification of the frame and its load frame established by the finite element software ANSYS finite element model to study the method of simulation of structural connection , bending the frame at full load , full load reverse the emergency brake three workers the conditions were static analysis , analysis of structural stress concentration , the improved structure of the proposal . Frame finite element model based on the calculation of the frame in the free state, the first fifteen order modal characteristics frame natural frequencies and modes , and analysis of its vibration characteristics ; simulation of the car over the slope process to analyze the transient dynamic response characteristics of the frame . Based on modal analysis , by car rack width , thickness and other dimensions of the structural parameters , the establishment of the parametric model , lightweight design of the frame .
