Description

Technical Field

[0002] Compared to other ship types, cruise ships are not only a means of transport for tourism but also a place for leisure and recreation. This necessitates more stringent requirements for comfort than for commercial and passenger ships, necessitating cruise ship noise prediction design. However, cruise ships feature multi-deck superstructures housing numerous passenger cabins, dining areas, sanitary and recreational facilities, and travel at high speeds. This multi-deck superstructure, the large number and variety of passenger cabins and recreational areas, and the numerous vibration and noise sources make cruise ship noise prediction design a complex and challenging undertaking.

[0003] Currently, three main methods are commonly used for cruise ship noise prediction: empirically based formula estimation, engineering estimation based on a database of prototype ships, and numerical prediction.

[0068] Example 1

[0069] This embodiment provides a method for constructing a hull noise design, such as Figure 1 As shown, the construction method includes:

[0070] S101, obtaining the noise source of the area to be evaluated;

[0071] S102, inputting the noise source into a preset noise prediction model to obtain an evaluation result of the area to be evaluated;

[0072] S103 : Based on the evaluation result, adjust the noise-sensitive components or noise sources corresponding to the area to be evaluated so that the noise value of the area to be evaluated meets the corresponding preset noise standard.

[0073] In this plan, based on the noise causes in different areas of the cruise ship and the vibration and noise reduction design process, a combination of one or more numerical analysis methods is used to carry out noise prediction design for the corresponding areas of the cruise ship, which can effectively reduce workload and improve work efficiency.

[0074] As an achievable manner, the hull includes a bottom working area, a tourist activity area, and an open-air deck area, and step S101 includes:

[0075] determining a position of the area to be assessed in the hull;

[0076] In response to the area to be evaluated being a bottom-layer working area, obtaining a first model corresponding to the bottom-layer working area, as well as a device noise source and a first air noise source in the bottom-layer working area;

[0077] In response to the area to be evaluated being a tourist activity area, obtaining a second model corresponding to the tourist activity area and a vibration noise source in the tourist activity area;

[0078] In response to the area to be evaluated being an open-air deck area, a third modeling corresponding to the open-air deck area and a second air noise source in the open-air deck area are obtained.

[0079] This design divides the cruise ship into three sections: the area from the bottom of the ship to 4-5 decks above the engine room as the lower work area, the area above 4-5 decks above the engine room as the passenger activity area, and the open-air deck area. In the lower work area, the primary considerations are structure-borne noise and airborne noise generated by large engine room equipment; in the passenger activity area, the primary considerations are noise from the air conditioning and ventilation systems and air conditioning station equipment; and in the open-air deck area, the primary consideration is noise from the engine room exhaust vents and air conditioning ventilation inlets and outlets. This design approach prioritizes noise generation in different cruise ship areas and the vibration and noise reduction design process, ensuring efficient and accurate design.

[0080] As an achievable manner, the area to be assessed is a bottom working area, the noise-sensitive components include a deck covering and / or a floating floor, and the step of inputting the noise source into a preset noise prediction model to obtain an assessment result of the area to be assessed includes:

[0081] Obtaining a structure-borne noise excitation corresponding to a noise source of the device;

[0082] Inputting the structure-borne noise excitation and the equipment noise source into a first preset noise prediction model to obtain a first noise value for each cabin in the bottom working area;

[0083] comparing the first noise value corresponding to each of the cabins with a first preset standard threshold;

[0084] In response to the first noise value of any of the cabins being greater than the first preset standard threshold, the first evaluation result is negative;

[0085] The step of adjusting the noise-sensitive components or noise sources corresponding to the area to be evaluated based on the evaluation result so that the noise value of the area to be evaluated meets the corresponding preset noise standard includes:

[0086] In response to the first evaluation result being negative, adjusting the laying of the deck covering and / or the laying of the floating floor until the first evaluation result is positive;

[0087] In response to the first evaluation result being positive, the adjusted first modeling is used as the first target noise modeling of the underlying working area.

[0088] In this scheme, the first preset noise prediction model adopts the noise forecast statistical energy model. The main research object of the bottom working area is the area from the bottom of the ship to the 4th to 5th decks above the engine room. Through the first modeling of the accurate modeling of the bottom working area, the noise values ​​of the cabins and public areas in the bottom working area are calculated, and the first noise value obtained by the noise forecast statistical energy model is compared with the first preset standard threshold required by the corresponding standard for the bottom working area.

[0089] For cabins that do not meet regulatory requirements, since structure-borne noise is primarily transmitted through structures such as decks, pillars, and bulkheads, noise control in accommodation and public areas is primarily achieved through the installation of deck coverings / floating floors. Appropriate deck coverings and / or floating floors are selected and applied, including the type, material, and thickness of the deck coverings and / or floating floors. The adjusted deck coverings and / or floating floors in the first modeling process are used to achieve a first target noise model that meets regulatory requirements. This solution provides efficiency and accuracy based on the design process for noise contributions in lower-level working areas.

[0090] As an achievable approach, the construction method further includes:

[0091] In response to the first evaluation result being positive, applying a sound-isolating insulation structure based on the first target noise modeling;

[0092] Obtaining a first air noise excitation corresponding to a first air noise source;

[0093] inputting the first preset noise prediction model with the first air noise source and the first air noise excitation to obtain a second noise value for each cabin in the bottom working area;

[0094] comparing the second noise value corresponding to each of the cabins with a second preset standard threshold;

[0095] In response to the second noise value of any of the cabins being greater than the first preset standard threshold, the second evaluation result is negative;

[0096] In response to the second evaluation result being negative, adjusting the sound insulation structure in the first target noise modeling until the second evaluation result is positive;

[0097] In response to the second evaluation result being positive, the adjusted first target noise modeling is used as the second target noise modeling of the bottom working area.

[0098] In this solution, since airborne noise is attenuated as it propagates through bulkheads and decks, based on the aforementioned model, appropriate sound insulation is applied to steel enclosures or deck countertops, depending on the zone type and noise limit requirements for each zone. Based on the first target noise modeling, appropriate sound insulation is applied based on the zone type within the lower-level work area. For cabins that do not meet regulatory requirements, the sound insulation applied between zones is optimized and adjusted to achieve a second target noise modeling that meets regulatory requirements. This solution provides efficient and accurate construction based on the design process for the causes of noise in the lower-level work area.

[0099] As an achievable method, the area to be evaluated is a tourist activity area, and the vibration noise source includes air conditioning station equipment. The steps of inputting the noise source into a preset noise prediction model to obtain an evaluation result of the area to be evaluated include:

[0100] Obtaining a vibration noise excitation corresponding to the vibration noise source;

[0101] Inputting the vibration noise excitation and the equipment noise source into a second preset noise prediction model to obtain a third noise value for each cabin in the visitor activity area;

[0102] comparing the third noise value corresponding to each of the cabins with a third preset standard threshold;

[0103] In response to the third noise value of any of the cabins being greater than the third preset standard threshold, the third evaluation result is negative;

[0104] The step of adjusting the noise-sensitive components or noise sources corresponding to the area to be evaluated based on the evaluation result so that the noise value of the area to be evaluated meets the corresponding preset noise standard includes:

[0105] In response to the third evaluation result being negative, adjusting the position of the air conditioning station equipment until the third evaluation result is positive;

[0106] In response to the third evaluation result being positive, the adjusted second modeling is used as the third target noise modeling for the tourist activity area.

[0107] In this solution, the second preset noise prediction model uses a noise forecast statistical energy model. The primary research area for the tourist activity zone is the area above decks 4 and 5 above the engine room, where noise primarily originates from the air conditioning system. Therefore, multiple local models can be established for the air conditioning stations within the tourist activity zone, including local models of the air conditioning stations and surrounding cabins, to design noise forecasts for each of these areas. Through a second modeling process that accurately models the tourist activity zone, noise levels in the cabins and public areas within the zone are calculated. The second noise value obtained from the noise forecast statistical energy model is then compared with the second preset standard threshold required by the corresponding standard for the tourist activity zone.

[0108] For cabins that don't meet regulatory requirements, we analyze the primary noise sources and implement targeted vibration and noise reduction controls on the air conditioning station equipment. By adjusting the vibration of the air conditioning station equipment in the second model, we achieve a third target noise model that meets regulatory requirements. This solution prioritizes the design process based on the noise contributing factors in tourist activity areas, ensuring efficiency and accuracy.

[0109] As an achievable approach, the vibration noise source further includes an air-conditioning pipeline of an air-conditioning station equipment, and the construction method further includes:

[0110] In response to the third evaluation result being positive, calculating a fourth noise value of the air conditioning pipeline in the third target noise modeling;

[0111] superimposing the third noise value and the fourth noise value to obtain a superimposed noise value;

[0112] comparing the superimposed noise value corresponding to each of the cabins with a fourth preset standard threshold;

[0113] In response to the superimposed noise value of any of the cabins being greater than the fourth preset standard threshold, the fourth evaluation result is negative;

[0114] In response to the fourth evaluation result being negative, adjusting the position of the air conditioning station equipment in the third target noise modeling until the fourth evaluation result is positive;

[0115] In response to the fourth evaluation result being positive, the adjusted third target noise model is used as the fourth target noise model for the tourist activity area.

[0116] In this solution, because the noise from the air conditioning station equipment is the sum of noise from multiple units, as well as noise caused by vibration from pipe strips, the air conditioning station system and its piping are modeled. Using the CFD simulation results of the air conditioning piping as input, the finite element method or boundary element method is used to predict the piping noise, resulting in a fourth noise value. In one embodiment, a determination is made as to whether the fourth noise value meets the cabin's regulatory requirements. If the fourth noise value does not meet the cabin's regulatory requirements, the air conditioning piping noise is controlled, including by adjusting the piping layout, replacing piping materials, and / or installing soundproofing materials, until the fourth noise value meets the cabin's regulatory requirements within the visitor activity area.

[0117] If the superimposed noise level doesn't meet the cabin regulations for tourist activity areas, further vibration and noise reduction can be implemented on the air conditioning station equipment and system piping. This can be achieved by adjusting the location of the air conditioning station equipment to avoid resonance. Furthermore, by adjusting the location of the air conditioning station equipment and the routing of the air conditioning piping, the length of the piping can be shortened as much as possible to reduce vibration. This solution provides efficiency and accuracy based on the design process for noise contributors in tourist activity areas.

[0118] As an achievable manner, the area to be evaluated is an open deck area, the second air noise source includes an air outlet, and the step of inputting the noise source into a preset noise prediction model to obtain an evaluation result of the area to be evaluated includes:

[0119] Obtaining a second air noise excitation corresponding to the second air noise source;

[0120] inputting the second air excitation and the second air noise source into a third preset noise prediction model to obtain a fifth noise value of the open deck area;

[0121] comparing the fifth noise value with a fifth preset standard threshold;

[0122] In response to the fifth noise value being greater than the fifth preset standard threshold, the fifth evaluation result is negative;

[0123] The step of adjusting the noise-sensitive components or noise sources corresponding to the area to be evaluated based on the evaluation result so that the noise value of the area to be evaluated meets the corresponding preset noise standard includes:

[0124] In response to the fifth evaluation result being negative, adjusting the position of the air outlet until the fifth evaluation result is positive;

[0125] In response to the fifth evaluation result being positive, the adjusted third modeling is used as the fifth target noise modeling for the weather deck area.

[0126] In this solution, the third preset noise prediction model adopts a noise prediction local model. Targeting the local models of different open-air deck areas, the model calculates the noise radiated from the exhaust port and the air inlet and outlet to the open-air deck area. The fifth noise value obtained by the noise prediction local model is compared with the fifth preset standard threshold required by the corresponding standard for the open-air deck area.

[0127] For cabins that do not meet regulatory requirements, noise from engine room exhaust vents and air conditioning ventilation inlets and outlets is controlled. This includes adjusting the size and shape of the vents, installing silencers, adjusting the speed and blade design of the exhaust fans, and installing sound barriers or enclosures in open-air deck areas. Adjusting the length, diameter, and curvature of the exhaust ducts reduces turbulence and eddies within the ducts, thereby reducing noise. This solution addresses the design process for noise-causing factors in lower-level work areas, providing efficiency and accuracy.

[0128] The method for constructing hull noise design provided in this embodiment uses different calculation methods for different areas of the cruise ship, thereby reducing workload, improving work efficiency, and performing noise prediction design for different areas of the cruise ship in a targeted manner.
