Research on Modeling and Simulation of Controllable Pitch Propeller Propulsion Plant and Its Control System
Computer Simulation, 2007Co-Authors: Wu ShuangAbstract:Based on the quasi-steady modeling method and cycle mean value modeling method, a propulsion plant real-time simulation model including MAN BW 6S35MC diesel engine, controllable pitch Propeller (CPP), hydraulic servo unit, DGS8800e digital governor, MAN BW MC pneumatic maneuvering system and Alphatronic 2000 PCS propulsion con- trol system was proposed. A CPP propulsion plant real-time simulation system for nautical manoeuvres was developed. The simulation curves at steady, dynamic and crash astern were represented. The simulation and experimental results show that the model can be used for the CPP propulsion plant performance prediction under steady state and dynamic state.

ECC - A study of ship's mooring method with Controllable Pitch Propeller (CPP) by applying generalized minimum variance control
2013 European Control Conference (ECC), 2013Co-Authors: Masayoshi Doi, Kazutoshi Nagamoto, Tetsuya TakehiraAbstract:The purpose of this study is to improve a mooring system with Controllable Pitch Propeller (CPP). Because of the slip of Propeller, velocity response of CPP has time delay. In this study, the ship's propelling force with the CPP's angle was identified on an actual ship and delay time was observed by analyzing the data of propelling force. Then the CPP angle is controlled by using Generalized Minimum Variance Control (GMVC) to obtain better performance for the mooring system.

Delay time of propelling force with ship's Controllable Pitch Propeller (CPP)
2009Co-Authors: Masayoshi Doi, Kazutoshi Nagamoto, Tetsuya Takehira, Yasuchika MoriAbstract:The purpose of this study is the identification of delay time of a design method that make a controller for a system with a delay time in the case of a Controllable Pitch Propeller (CPP). A velocity response of CPP has delay time until reaching the setting CPP's angle and due to Propeller's slip. Especially, this study verifies the ship's propelling force against the CPP's angle and detects delay time by analyzing the data of the propelling force.

Stress analysis on blade-base-bolt of controllable pitch Propeller
Computer-Aided Engineering, 2010Co-Authors: Yang WenkaiAbstract:As to the issue that there exists stress concentration in the rounding transition field between the top and the screw of the blade-base-bolt of a controllable pitch Propeller,based on elastic and elastic-plastic theory,MSC Marc is used to analyze the stress distribution of the blade-base-bolt which is under the pre-load status and the status that the Propeller is in work. For the analysis,the section method and the penetration contact method are used to calculate the load of pre-load force. The results indicate that,during the period of the Propeller is in work,small plastic deformation occurs in the rounding transition field between the top and the screw of the blade-base-bolt and has a little effect on the strength of the bolt;both the section method and the penetration contact method can simulate the pre-load process of the bolt effectively.
