Abstract

The invention discloses a method for testing the service life of a deceleration strip. The method comprises the following steps of establishing the two-dimensional and three-dimensional models of thedeceleration strip; establishing a spring two-vibration subsystem to simulate the stress condition of a vehicle passing through the deceleration strip, and obtaining a stress curve graph of the contact points of the wheels and the deceleration strip; carrying out the structural static analysis on the deceleration strip by utilizing the finite element analysis; selecting a rated load to test the deceleration strip to obtain a strain value and an equivalent stress value; and obtaining the service life of the deceleration strip according to the stress value and the equivalent strain value of thedeceleration strip. By establishing the two-dimensional and three-dimensional models, carrying out static analysis by adopting a finite element, testing the stress and strain values of three parts ofthe deceleration strip, and calculating the cycle index by utilizing the stress and strain values respectively, the test process of the service life of the whole deceleration strip is simplified, thetheoretical analysis is simpler and more feasible and has the economical efficiency, the service life of the deceleration strip is comprehensively evaluated, and a test means with higher reliability is provided.

Description

technical field [0001] The invention relates to the field of life testing of speed bumps, in particular to a method for testing the life of speed bumps. Background technique [0002] As an enhanced road traffic safety facility, speed bumps have played an important role in curbing traffic accidents. Therefore, the application of speed bumps has been widely popularized, but some problems have also been exposed in the specific use of speed bumps. A series of problems, such as the speed bump is easily damaged, the service life is short, and it cannot be recycled and reused after being discarded. It is necessary to carry out specific tests on the speed bump before it is put into use, so that some products with better performance can be put into use. At present, the evaluation system for the service life of speed bumps is not perfect. Speed ​​bumps are easily damaged during use and have a short service life. After the speed bumps are discarded, the environment and resources are wa...
