Problems solved by technology

[0004] However, the disadvantages of component simulation analysis are: 1. A large amount of data accumulation is required to set the simulation working conditions, and the process is cumbersome; 2. Analysts need rich experience to correctly eliminate interference factors; 3. Different analysis methods, The accuracy of analysis by different personnel is relatively large
The prototype road test will lead to: 1. The verification time period is longer; 2. The verification cost is higher

Abstract

The invention discloses an automobile body installation reliability test method. An automobile passes through a specific obstacle at a set speed under control, and whether a part under test meets thereliability requirement is determined according to the moment attenuation value and deformation value of the part under test. Quantitative test can be conducted by using the method. The test process is simple. The relevant performance can be evaluated intuitively. The results are accurate. The cycle is short, and the cost is low.

Description

technical field [0001] The invention relates to the field of automobile installation, in particular to an automobile body installation reliability test method. Background technique [0002] With the continuous increase of automobile sales in the Chinese market, the requirements for the strength and durability of auto parts in the domestic market are also increasing. Therefore, it is necessary to test the strength and durability of parts; [0003] At present, the strength of parts is checked through simulation analysis in the part design stage, or the strength and durability of parts are checked through a reliability road test with a certain mileage in the prototype stage. [0004] However, the disadvantages of component simulation analysis are: 1. A large amount of data accumulation is required to set the simulation working conditions, and the process is cumbersome; 2. Analysts need rich experience to correctly eliminate interference factors; 3. Different analysis methods, ...
