Abstract

The invention belongs to the technical field of racing car lightweight design, and particularly relates to a formula car frame lightweight design method, which comprises the following steps: determining frame parameters; building a frame main body model by combining the man-machine parameters and the whole vehicle parameters with a competition rule; carrying out topological optimization on the frame main body model to obtain a mass minimum rod piece distribution map under the target rigidity; analyzing the size of the frame by using a topological analysis result; and the data quality and the comprehensive torsional rigidity value of the frame model are evaluated, an optimal frame model is selected, and lightweight design is completed. According to the method, the problem that the lightweight design of the current formula car frame does not have a clear evaluation index is solved, the reasonability and normalization of the lightweight design of the frame are effectively improved, the design efficiency is greatly improved, the design period is shortened, and the performance requirement of the whole car frame is met.

Description

technical field [0001] The invention belongs to the technical field of lightweight design for racing cars, and in particular relates to a lightweight design method for a frame of a formula racing car. Background technique [0002] The Chinese Formula Car Competition was established in 2010. According to the technical rules issued by the organizing committee of the competition, a single racing small car was designed, manufactured and trained in one year. Its biggest feature is that the design and manufacture of the car must be Comply with technical regulations. As the largest structural component independently designed and manufactured by a formula racing car, the frame is the carrier of each assembly of the vehicle and plays an important role in arranging the overall and connecting the assembly. The frame is designed with high strength, high rigidity, comfort and light weight. Among the design goals, light weight and high rigidity are particularly important, that is, the fr...
