【摘要】：随技术的不断进步,现代化的战争对装备的快速性、隐蔽性等提出要求,提高我军近海侦察和作战能力势在必行。带有潜水功能的两栖快艇具有“水上快速而隐蔽、陆上机动而灵活、并且能够短时潜水避敌”的特性,在军用和民用方面体现出极大研究意义。本文主要目的是研究两栖快艇设计的可行性,提出一种总体设计方案,并且针对两栖快艇涉及的两项关键技术进行深入探讨与研究。本文通过分析各国对两栖装备的研究成果,总结出两栖快艇设计所涉及的关键技术,如可收放悬架技术、滑行艇体技术、喷水推进技术等。借鉴现有成熟的两栖装备技术参数以及设计经验,对两栖快艇进行了总体方案设计,详细阐述了设计过程中涉及的各模块参数部件的选取以及选取原由,并对选取的模块进行了布置草图设计。总体设计之后,针对其涉及的可收放悬架和滑行艇体两项关键技术做重点研究,这两项技术均是用于保障两栖快艇的高航速特性。首先文中对可收放悬架技术的研究现状作了简要分析,参照成熟的设计理念,提出一种全新的适用于本文设计的两栖快艇的可收放悬架方案,对其机械结构方案、液压系统方案、相关件的定位、干涉以及设计注意点等做了详细叙述,并且设计了陆上工况悬架系统收放失效功能。然后运用CATIA软件建立其简化模型,在DMU模块中对其进行运动仿真,测定相关技术参数以及干涉、碰撞分析等。再而文中对艇体航行阻力的构成以及阻力特性、航态特性详细分析,结合分析结果确定适用于两栖快艇的艇体方案。对滑行艇特性进行了总结,并分析提出艇体在设计过程中需要注意的关键点。最后针对由于悬架系统的配备而带来的不可避免的艇体前、后轴部位凹陷,设计出一种凹陷弥补机构,该机构方案能能够增加艇身的流线型,提高两栖快艇的航速。
[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.
