【摘要】：隨技術(shù)的不斷進(jìn)步,現(xiàn)代化的戰(zhàn)爭對裝備的快速性、隱蔽性等提出要求,提高我軍近海偵察和作戰(zhàn)能力勢在必行。帶有潛水功能的兩棲快艇具有“水上快速而隱蔽、陸上機(jī)動而靈活、并且能夠短時潛水避敵”的特性,在軍用和民用方面體現(xiàn)出極大研究意義。本文主要目的是研究兩棲快艇設(shè)計的可行性,提出一種總體設(shè)計方案,并且針對兩棲快艇涉及的兩項關(guān)鍵技術(shù)進(jìn)行深入探討與研究。本文通過分析各國對兩棲裝備的研究成果,總結(jié)出兩棲快艇設(shè)計所涉及的關(guān)鍵技術(shù),如可收放懸架技術(shù)、滑行艇體技術(shù)、噴水推進(jìn)技術(shù)等。借鑒現(xiàn)有成熟的兩棲裝備技術(shù)參數(shù)以及設(shè)計經(jīng)驗,對兩棲快艇進(jìn)行了總體方案設(shè)計,詳細(xì)闡述了設(shè)計過程中涉及的各模塊參數(shù)部件的選取以及選取原由,并對選取的模塊進(jìn)行了布置草圖設(shè)計�？傮w設(shè)計之后,針對其涉及的可收放懸架和滑行艇體兩項關(guān)鍵技術(shù)做重點研究,這兩項技術(shù)均是用于保障兩棲快艇的高航速特性。首先文中對可收放懸架技術(shù)的研究現(xiàn)狀作了簡要分析,參照成熟的設(shè)計理念,提出一種全新的適用于本文設(shè)計的兩棲快艇的可收放懸架方案,對其機(jī)械結(jié)構(gòu)方案、液壓系統(tǒng)方案、相關(guān)件的定位、干涉以及設(shè)計注意點等做了詳細(xì)敘述,并且設(shè)計了陸上工況懸架系統(tǒng)收放失效功能。然后運用CATIA軟件建立其簡化模型,在DMU模塊中對其進(jìn)行運動仿真,測定相關(guān)技術(shù)參數(shù)以及干涉、碰撞分析等。再而文中對艇體航行阻力的構(gòu)成以及阻力特性、航態(tài)特性詳細(xì)分析,結(jié)合分析結(jié)果確定適用于兩棲快艇的艇體方案。對滑行艇特性進(jìn)行了總結(jié),并分析提出艇體在設(shè)計過程中需要注意的關(guān)鍵點。最后針對由于懸架系統(tǒng)的配備而帶來的不可避免的艇體前、后軸部位凹陷,設(shè)計出一種凹陷彌補(bǔ)機(jī)構(gòu),該機(jī)構(gòu)方案能能夠增加艇身的流線型,提高兩棲快艇的航速。
[Abstract]:With the continuous progress of technology, modern warfare demands the rapidity and concealment of equipment, so it is imperative to improve our military's offshore reconnaissance and combat capability. The amphibious speedboat with diving function has the characteristics of "fast and hidden on water." The characteristics of land maneuvering and flexibility, and being able to avoid enemies in short time, are of great significance in military and civil fields. The main purpose of this paper is to study the feasibility of amphibious speedboat design and to put forward a general design scheme. By analyzing the research results of amphibious equipment in various countries, the key technologies involved in the design of amphibious speedboats, such as retractable suspension technology, are summarized. Based on the existing mature amphibious equipment technical parameters and design experience, the overall scheme design of amphibious speedboat is carried out. The selection of parameter components of each module and the reasons for the selection are described in detail. After the overall design, the selected modules are arranged and sketched. This paper focuses on two key technologies involved in retractable suspension and glide hull, both of which are used to guarantee the high speed characteristics of amphibious speedboats. Firstly, the research status of retractable suspension technology is briefly analyzed in this paper. Referring to the mature design concept, a new retractable suspension scheme for amphibious speedboats designed in this paper is put forward. The interference and the design points are described in detail, and the failure function of suspension system under the condition of land is designed. Then the simplified model is established by using CATIA software, and the motion simulation is carried out in the DMU module. Measurement of the relevant technical parameters, interference, collision analysis, etc. Then, the composition and characteristics of the ship's navigation resistance and the characteristics of the ship's navigation state are analyzed in detail. Combined with the analysis results, the hull scheme suitable for amphibious speedboats is determined. The characteristics of the gliding boats are summarized. The key points in the design process of the hull are analyzed and put forward. Finally, aiming at the inevitable depression in the front and rear axle of the hull due to the installation of the suspension system, a recess compensation mechanism is designed. The scheme can increase the streamline of the boat and increase the speed of the amphibious speedboat.
