[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.
