| description | In view of the problem that the collection of vehicle load must be completed after the prototype car is completed,and the necessary load data are often lacking in the product development stage,the standardization of load spectrum under the endurance criterion of the proving ground is studied in this paper.Firstly,the characteristics of the measured load spectrum of different vehicle types in a domestic proving ground are analyzed,and the consistency of the frequency distribution of rainflow cycles for different vehicle types is clarified.Furthermore,the validity of the traditional probability distribution model and the extreme value distribution model in the rainflow cycle modeling is compared by synthesizing the difference of load frequency distribution and damage interval distribution.Through load frequency and damage distribution,the rationality of the exceeding threshold distribution model in load modeling is verified.Finally,the standardized load model of the proving ground is established by normalizing the loads of different types of vehicles.The validity and rationality of the standardized load model are verified by comparing the rainflow cycle,pseudo-damage and fatigue life of the standardized load spectrum with the measured load spectrum in proving grounds.The standardized load spectrum and load spectrum standardization method can provide accurate and effective load data for new vehicle in the early development stage,so as to ensure product reliability and durability level. |
