Alternative frame simulation method and simulation system based on three-dimensional modeling

Abstract

The invention belongs to the technical field of alternative frames, and discloses an alternative vehicle frame simulation method and simulation system based on three-dimensional modeling. The method comprises the following steps of: performing modeling suitable for replacing a frame by using three-dimensional modeling software, performing a carbon fiber composite laminate elastic constant test experiment, analyzing a laying angle and a laying thickness design by using ANSYS, and performing analysis under various working conditions to obtain a specific process flow of the carbon fiber compositematerial suitable for replacing the frame; carrying out torsional rigidity and flexural rigidity simulation analysis, static load, braking, sharp turn working condition simulation analysis and modalanalysis on the alternative vehicle frame, and finally elaborating the technological process of the alternative vehicle frame. The alternative frame is a sandwich structure shell which takes a high-rigidity and light-weight carbon fiber / epoxy resin composite material as a panel and takes a low-density and low-strength aluminum honeycomb as a core material, and has the advantages of high torsionalrigidity, light weight, accuracy and convenience in assembly and positioning, free and attractive appearance and the like.

Description

technical field [0001] The invention belongs to the technical field of replacement frames, in particular to a simulation method and simulation system for replacement frames based on three-dimensional modeling. Background technique [0002] At present, alternative frame technology and composite material technology first originated on ships and aircraft, such as the Boeing B787, which used a large number of composite materials on the aircraft fuselage and aircraft wings, and began to be used in automobiles in 1969. The development and use of new materials is imperative. [0003] It is the first time that the F1 race has a suitable alternative frame and it is widely known that the LOTUS25 that participated in the F1 race in 1962 used a light metal shell frame, and it can also be regarded as the originator of the current substitute frame. This car has less weight, good vision, greater torsional stiffness, and a more spacious cockpit. In the 1962 season, there were ten races in ...

Problems solved by technology

Due to the constraints of practical factors, many students know the advantages of replacing the frame, but they can only be a little envious. Because of the constraints of practical factors, they know that the implementation of the replacement frame is unlikely, and they lose their research on this aspect over time.
