Evaluation method for predicting whistle of tip opening of automobile engine hood

The invention discloses an evaluation method for predicting the whistle of an automobile engine hood tip opening, and belongs to the technical field of automobile engine hood tip opening whistle evaluation, and the evaluation method is based on an engine hood tip opening whistle generation mechanism, engineering experience and a multivariate adaptive regression spline method. According to the method, automobile DPA inspection is a means for inspecting the design of automobile parts and the relative position relation between the parts by utilizing digital-analog software and combining engineering experience, and the main purpose is to identify risk points in a digital sample automobile development stage, solve the risk points and reduce the occurrence of problems in the sample automobile stage; according to the prediction and evaluation method, the whistle risk of the tip opening of the engine hood can be effectively identified in a new vehicle type digital sample vehicle stage; by means of the method, only th
