## 方程式赛车设计体布置设计

Abstract
General layout design continues in the whole process of vehicle develop-
-pment, and plays an extremely important role in the process of vehicle
development. And formula SAE or formula student racing car is a small and
single-seat car which is good at accelerating, braking, playability and
comply with the rules. So according to the method of general automobile
layout design, this paper tries to design the formula SAE racing car. And
this paper  completes  the overall parameters and the selection of the car’s
principal assembly. At the same time, on the basis of the car’s detailed
design, this paper calculates and simulates the various performance of
complete vehicle.  Especially according to the multi-body dynamics theory,
ADAMS/CAR software and the national standards, this paper evaluates the
handling stability and tries to research a set to evaluate formula SAE
racing car. Finally, according to the general layout design, this paper

draws the general layout drawing.
