Abstract EN
In practical engineerings, structures are often excited by different kinds of loads at the same time.
How to effectively analyze and simulate this kind of dynamic environment of structure, named combined dynamic environment, is one of the key issues.
In this paper, a novel prediction method of combined dynamic environment is proposed from the perspective of data analysis.
First, the existence of dynamic similarity between vibration responses of the same structure under different boundary conditions is theoretically proven.
It is further proven that this similarity can be established by a multiple-input multiple-output regression model.
Second, two machine learning algorithms, multiple-dimensional support vector machine and extreme learning machine, are introduced to establish this model.
To test the effectiveness of this method, shock and stochastic white noise excitations are acted on a cylindrical shell with two clamps to simulate different dynamic environments.
The prediction errors on various measuring points are all less than ±3 dB, which shows that the proposed method can predict the structural vibration response under one boundary condition by means of the response under another condition in terms of precision and numerical stability.
