Design And Simulation Of Adjustment Mechanism Of Variable Vector Propeller

The underwater equipments are of importance in ocean exploration and research, as well as in national defence. The special applying environment requires more compact, lightweight and small with its structure. The propellers of underwater equipments usually use ordinary screws, which can only produce propulsive force from ahead and back, which hinders the development of underwater equipments to a great extent. Variable vector propellers is emerged as the times require, whose biggest advantages are producing propulsive force from all the directions with the periodical change of pitch angle.In the paper, The main work is as follows: the design on blade adjustment mechanism of the variable vector propeller, and the algorithm analyse on kinematic relation as well as the kinematic simulation and dynamical analyse of pitch angle based on Virtual Prototyping Technology.Through the analyse of correlative literature and design conditions from home and abroad, the basic design scheme and the whole design scheme are built using disk blade adjustment mechanism. The kinematics relationship between pitch angle and the handspike is very important. A solution scheme to the complex spatial mechanism is developed which is predigested and needful, also the algorithm is put forward and realized in Java platform. The material, shapes and structures of the mechanism parts are confirmed respectively with trial parameter abroad and the real need, some of which are checked to obtain security and reliability.Virtual Prototyping Technology is very important in mechanism design. The kinematic simulation of virtual prototyping model is built for the variable vector propeller in Pro/E, and the kinematics and dynamics characters of the model are analyzed in ADAMS by the Mechanism/Pro interface statement.
