Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0057] The vehicle stress belt bridge system is composed of a stress belt bridge and vehicles driving on the stress belt bridge. Due to the elasticity of the vehicle and the tension of the stress belt bridge, the vehicle stress belt bridge system is a nonlinear coupling system.

[0058] In this embodiment, the vibration of the vehicle stress belt bridge system is controlled by setting an eddy current tuned mass damper (hereinafter referred to as a damper) on t...

Abstract

The invention relates to the technical field of bridge engineering, and particularly relates to a stressed ribbon bridge vehicle-induced vibration control method based on an eddy current tuned mass damper. The method comprises the steps of for a vehicle stressed ribbon bridge system, respectively solving dynamic responses in an uncontrolled state and a controlled state, wherein the controlled state is that an eddy current tuned mass damper is added into the vehicle stressed ribbon bridge system, and the uncontrolled state is that no eddy current tuned mass damper is added to the vehicle stressed ribbon bridge; establishing a response surface model based on the eddy current tuned mass damper; constructing a damper parameter optimization objective function according to the peak values of thedynamic response in the uncontrolled state and the controlled state; optimizing the damper parameters by utilizing the damper parameter optimization objective function and the response surface model,and determining the optimal damper parameters; and setting the vehicle stressed ribbon bridge system according to the optimal damper parameters. The method is suitable for a nonlinear coupling system, and a better bridge vibration control effect is achieved by using the eddy current tuned mass damper.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a vehicle-induced vibration control method for a stressed belt bridge based on an eddy current tuned mass damper. Background technique [0002] Currently, research on the vibration control of belt bridges loaded with moving vehicles, the existing work mainly focuses on linear vibration control using traditional tuned mass dampers, which assumes the vibration control of linear vehicle belt bridge systems , to study the response in this case. The above method has two problems: 1. It is not suitable for the vibration control of the non-linear vehicle belt bridge system, resulting in poor system control efficiency. 2. The response measured at the same time cannot reflect the actual situation, and the error caused by the analysis under certain circumstances is relatively large. Contents of the invention [0003] In order to solve the above technical problems, the presen...
