[Abstract]:Shipbuilding industry is a strategic industry to provide technical equipment for marine transportation, marine development and national defense construction in China. Marine power plant is the key development direction for the revitalization and adjustment of China's shipbuilding industry. As a kind of marine power device, cycloidal propeller can change the size and direction of propulsion force without changing the speed of propeller drive, and has excellent maneuverability and high maneuverability of ship. It is widely used in every major port in the world. At present, the advanced technologies related to cycloidal thrusters are monopolized by Germany's Foyt Company. The existing cycloidal thrusters in China are seriously worn out and difficult to maintain. It is of great significance to develop a new cycloid propeller with independent intellectual property rights for China's economic development and national defense construction. On the basis of analyzing the working principle of cycloidal thruster, a new type of cycloidal thruster structure design scheme based on planar six-bar mechanism is proposed in this paper. The law of blade swing of the propeller is analyzed by Simulink,ANSYS and other simulation software. The stress distribution of the core components verifies the feasibility of the scheme. Based on LabVIEW, the control system of double steering gear of propeller is developed, and the man-machine interaction and condition monitoring of cycloidal thruster are realized. The test platform of cycloidal thruster based on LMS is built. By testing the hydrodynamic performance of cycloidal thruster with different eccentricity, advancing speed coefficient and forward direction angle, the rationality of the design and development of cycloidal thruster is verified. The expected design goal has been achieved. The main research work is as follows: 1. Analyze the current situation of cycloidal thruster research at home and abroad and its application in ship industry, aviation field and energy field, and study the design scheme of cycloidal thruster. This paper analyzes the existing problems and causes of cycloidal thrusters at present. 2. The working principle of cycloidal thrusters is analyzed and the mathematical analysis model of cycloidal thrusters is established to complete the formula derivation of hydrodynamic performance index of cycloidal thrusters. The influence of eccentricity, advancing speed coefficient and forward direction angle on the hydrodynamic performance of cycloidal propeller is analyzed theoretically. 3. By comparing and analyzing the existing cycloidal thrusters, a new type of cycloidal propeller structure design scheme based on planar six-bar mechanism is put forward. The feasibility of the scheme is verified by Simulink simulation and ANSYS finite element analysis of the core components (spindle and rotary disk) which are subjected to periodic load by means of the Simulink simulation analysis of the blade swing law under the planar six-bar mechanism. The new type cycloidal thruster is processed, installed and debugged. 4. The combined control algorithm of double steering gear is put forward, and the cycloidal thruster control system based on LabVIEW is developed. The overall scheme of thruster control system is designed. The program flow of the two core modules of human-computer interaction and state monitoring is planned, and the theoretical derivation of the dual steering gear control algorithm involved in the control system is completed, and the development of the dual steering gear control system based on LabVIEW is completed according to the overall design scheme.
