According to the corresponding frequency response function, the corresponding model can analyze the input target excitation spectrum data and output the corresponding excitation simulation data.
[0043] In a possible embodiment, since different types of simulation models have different processing logics and emphases, the corresponding simulation model can be matched according to the corresponding frequency domain model, and the current target excitation spectrum data can be processed according to the matched simulation model.
[0044] Optionally, in the step of determining target excitation spectrum characteristic data based on the target excitation spectrum data, and determining the corresponding frequency domain model based on the target excitation spectrum characteristic data, the step also includes processing the target excitation spectrum data through a frequency sweeping signal to determine the frequency of the first target sinusoidal excitation spectrum, the frequency of the first random spectrum graph, the frequency of the second target sinusoidal excitation spectrum, and the frequency of the second random spectrum graph, performing feature recognition processing on the frequency of the first target sinusoidal excitation spectrum, the frequency of the first random spectrum graph, the frequency of the second target sinusoidal excitation spectrum, and the frequency of the second random spectrum graph through a trained frequency domain recognition model to determine the target excitation spectrum characteristic data, and matching in a frequency domain recognition database based on the target excitation spectrum characteristic data to determine the corresponding frequency domain model.

Generally speaking, the sinusoidal excitation spectrum is usually used to simulate a vibration environment with a single or main frequency component.
[0046] The frequency of the first random spectrum mentioned above can be the main frequency component in the random vibration signal generated by the electromagnetic oscillator. Generally speaking, the random spectrum usually simulates the non-periodic, randomly distributed vibrations that occur in natural environments or complex mechanical operations. This spectrum contains multiple frequency components and is used to evaluate the overall stability and performance of the system when facing uncertain vibration sources.
[0047] The frequency of the second target sinusoidal excitation spectrum mentioned above may refer to the basic frequency of the second sinusoidal wave excitation used by the electro-hydraulic oscillator, which is similar to the first target sinusoidal excitation and is used for periodic vibration analysis of a specific frequency. Due to different test requirements or system characteristics, the frequency may be different from the frequency of the first target sinusoidal excitation spectrum.
[0048] The frequency of the second random spectrum may be the main frequency component of the second random vibration signal generated by the electro-hydraulic oscillator, and this signal simulates a wider random vibration environment.

It can be understood that by collecting a large amount of excitation spectrum data and determining through experiments or simulations the corresponding frequency domain components that match the frequency data corresponding to the current excitation spectrum data.
[0053] The frequency domain recognition model to be trained may be any deep learning model that is not yet able to perform frequency domain recognition on the frequency of the input excitation signal.

[0057] In an embodiment of the present invention, the above parameter optimization direction can be used to adjust the excitation balance of the system according to the adjusted parameters. Generally speaking, this direction can be determined according to the classification corresponding to the target excitation spectrum data, and the corresponding frequency domain model is selected for simulation according to the classification. Specifically, when the target excitation spectrum data of the electromagnetic exciter and the target excitation spectrum data of the electro-hydraulic exciter are sinusoidal spectra of the same frequency, and the target excitation spectrum data of the electromagnetic exciter and the target excitation spectrum data of the electro-hydraulic exciter are random spectra, select and ; When generating target excitation spectrum data for target sinusoidal excitation spectrum data of electromagnetic exciters of different frequencies and target sinusoidal excitation spectrum data of electro-hydraulic exciters and external data import, select .
