Prediction method of scrapping time of engineering machinery vehicles

Abstract

A prediction method of scrapping time of engineering machinery vehicles comprises the steps as follows: acquiring vehicle transmission shaft universal joint fit clearance sample data including sample data of different use time of different types of vehicles; establishing an engineering machinery vehicle use wear limited element prediction model according to the acquired sample data, and optimizing the wear model through limited element analysis, wherein a Bayes model is used for optimization, and experience information of experts and actual service life of the vehicles are added; judging used time of input universal joint fit clearances according to the wear model obtained in the last step; subtracting the used time from the years in forced scrapping regulations to obtain the predicted scrapping time. A reliable evaluation means is provided for remaining use time of the vehicles, and thus, the vehicle condition evaluation time and cost are greatly saved.

Description

technical field [0001] The invention relates to a vehicle scrapping test method, in particular to a test method for engineering machinery vehicle finite element analysis based on drive shaft testing. Background technique [0002] In recent decades, my country's automobile industry has developed rapidly, and the use of automobiles has its specific period, especially the country's mandatory scrapping period, which is a concern of many users and regulatory authorities. Construction machinery vehicles are usually used in harsh environments. Vehicles with poor conditions usually cause serious accidents to safety. Individual owners are usually unwilling to take the initiative to scrap and repair them, which often causes great danger. The management department needs a simple and reliable The evaluation method conducts accurate evaluation of construction machinery vehicles for supervision. Moreover, the recently developed second-hand car trading market needs a method to correctly a...
