Evaluation method of automobile ground line design scheme

Abstract

The invention relates to an automobile model development technology, in particular to an evaluation method of an automobile ground line design scheme. The evaluation method of the automobile ground line design scheme according to one embodiment comprises the following steps: obtaining ground line data by a ground line design input parameter, finished automobile load and a suspension rigidity parameter; obtaining a chassis part index and a finished automobile index of an automobile by the ground line data; scoring the chassis part index and the finished automobile index; according to an evaluation result, determining whether the chassis part index and the finished automobile index pass a preliminary design or not, if the chassis part index and the finished automobile index pass the preliminary design, generating a ground line preliminary design mathematic model, otherwise, revising the finished automobile load or the suspension rigidity parameter, and returning back to the step of obtaining the ground line data; measuring an automobile structure parameter by the ground line preliminary design mathematic model; and if the automobile structure parameter conforms to an engineering standard, determining a current ground line preliminary design mathematic model as a final ground line preliminary design mathematic model, otherwise, revising the finished automobile load or the suspension rigidity parameter, and returning back to the step of obtaining the ground line data.

Description

technical field [0001] The invention relates to a vehicle type development technology, in particular to an evaluation method of a vehicle ground line design scheme. Background technique [0002] In the development stage of the vehicle architecture, the ground line is a very important structural parameter. The ground line refers to the straight line formed by the ground contact point of the front tire and the rear tire of the vehicle under various loads. Key indicators such as styling design, vehicle size, layout of front cabin and chassis parts, vehicle safety analysis and vehicle wind resistance analysis are all calculated based on the ground line. [0003] figure 1 A flow chart of a prior art ground line design method is shown. like figure 1 As shown, in step S110 , the ground line design input parameters such as tire parameters, vehicle wheelbase, driver design position coordinates, fuel tank and trunk volumes are first input. Then enter step S120, calculate the tire...

Problems solved by technology

Moreover, in the early development stage of the vehicle, there is uncertainty and variability in the demand input, which makes the ground line design scheme change frequently, resulting in low work efficiency and affecting the development quality of the vehicle architecture.
