Problems solved by technology

[0004] Although the indoor simulation test can simulate the durability test of the automobile to a certain extent, the simulation effect is different due to the different simulation equipment used, and the indoor simulation test can only simulate a single component, such as wheels, brakes, brakes, etc. vibrator, etc., and the durability test cannot be performed on the entire vehicle
The existing proving ground field tests are only applied to a small number of models, and the current test methods are mostly random tests, and there is no systematic and comprehensive test method

Abstract

The invention discloses an automobile durability test method which is used for detecting test vehicles. A plurality of specified types of test vehicles are selected for testing in sequence, and if there is no obvious change in appearance and performance of all selected test vehicles, the type of test vehicles are judged to be qualified. The test method comprises the steps that the test vehicle passes through a test road section at a speed of 10-65km / h; the test vehicle passes through a brake test road section at a speed of 15-40km / h; and the test vehicle passes through an arch-shaped test roadsection at a speed of 10-60km / h. The test vehicle can be tested systematically and comprehensively by adopting different test road sections, so that the qualified test vehicle is enabled to meet thedriving under various road conditions, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to an automobile durability test method. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, automobiles have become one of the indispensable means of transportation for people to travel and freight. [0003] When the car leaves the factory or is promoted in batches, it is necessary to test the durability of the car to ensure the service life of the car. Existing automobile durability test methods include indoor simulation test and proving ground field test. The former is widely used in the durability test of various models because of its short test time, small space required, and easy automation test. [0004] Although the indoor simulation test can simulate the durability test of the automobile to a certain extent, the simulation effect is different due to the different simulation equip...
