Product Overview:

To assess the ability of various kinds of articles with specific loads to withstand actual road conditions in the process of road and automobile transportation, so as to obtain the influence of actual road conditions on the articles in the laboratory, so as to give the basis for evaluation or confirmation of the articles and their packaging.

Test purpose:

It is applicable to the acceleration simulation test of highway transportation of products transported by trucks to determine whether the products can adapt to the expected transportation vibration environment. The accelerated simulation test of highway transportation refers to the test which is consistent with the statistical characteristics of fatigue cumulative damage of automobile transportation environment by increasing the test value of simulated transportation vibration on the simulation platform in order to shorten the time of transportation simulation test.

Product features:

This paper will try to reproduce the vibration environment of the car in the process of driving on the highway in the laboratory. The method of frequency division approach is used to simulate broadband random vibration. Each frequency division contains a main natural frequency and satisfies the power spectrum of the frequency division. The vibration parameters of the transport platform are consistent with the actual road spectrum, and the rotating time of the test platform is equal to the actual time.
