Abstract

The embodiment of the invention discloses a real-time estimation method for structural vibration. The method comprises the following steps: acquiring a to-be-estimated measuring point of a to-be-measured structure, and determining a target measuring point associated with the to-be-estimated measuring point; acquiring coordinates, target modals and target vibration parameters corresponding to the target measuring points; determining a modal vibration parameter and an interpolation vibration parameter of the to-be-estimated measuring point based on the to-be-estimated measuring point in combination with the target modal, the target vibration parameter and the coordinate of each target measuring point; and determining an estimated vibration parameter of the to-be-estimated measuring point according to the modal vibration parameter and the interpolation vibration parameter. The invention can solve the problem that vibration parameters cannot be estimated in real time in an existing vibration parameter estimation method; therefore, the purpose of estimating the vibration parameter of the to-be-estimated measuring point in real time according to the vibration parameter of the associated target measuring point is achieved, and the estimated vibration parameter of the to-be-estimated measuring point can be estimated in real time; thus, the real-time performance and accuracy of data are guaranteed, the data processing time is saved, the reaction speed is increased, and the safety of equipment is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vibration estimation, and in particular, to a real-time estimation method for structural vibration. Background technique [0002] Vibration is a manifestation of a structure under external excitation, and any excitation will cause structural vibration. All large-scale equipment will have various structural vibrations during operation. When the structural vibration is large, it will damage the corresponding components or equipment, and even cause irreparable damage such as fracture. It is especially common in many fields such as transportation, rail transportation and marine transportation. Through vibration estimation, preventive maintenance can be effectively carried out, and the structural vibration of the equipment to be operated can be obtained in advance, so as to prevent unexpected structural vibration accidents under traditional technical means, evaluate the working status of...
