[Abstract]:The measurement and evaluation of underwater vehicle noise is a complicated and expensive work which is related to the key performance of the product.In this paper, a simple, fast and low cost ground vibration test is proposed for a certain UUV product, which is complex, time-consuming and expensive, and the evaluation of underwater noise of UUV is considered as the final research goal. Based on this, the feasibility study is carried out in this paper.In this paper, the mechanism of underwater noise generated by UUV is studied, and the mechanical noise, propeller noise and hydrohydrodynamic noise of UUV underwater navigation are analyzed and estimated in detail.Based on the vibration theory, the noise formation mechanism indicates that the ground vibration measurement of UUV is closely related to the underwater navigation noise, and the ultimate research goal proposed is feasible theoretically.On the basis of this, a complete UUV ground vibration acceleration test system and a propeller sound pressure test system are established, and the feasibility verification experiments are carried out.The experimental data processing and result analysis show that the research in this paper has achieved the goal of feasibility study, and has achieved periodic results: the mechanism of vibration and noise based on UUV underwater navigation and ground test,It is theoretically pointed out that it is feasible to predict the intensity of underwater navigation noise of UUV based on UUV ground correlation test, and a non-contact acoustic pressure test system of propeller based on UUV ground test is established, which provides a means for the measurement of propeller noise, which is an important correlation factor.The "cepstrum" signal analysis technology, which is more suitable for the periodic signal variation, provides a new data processing method for the fault diagnosis, analysis and noise reduction of UUV.
