Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] The invention belongs to the technical field of multiphase flow control simulation for high-speed navigation in water, and relates to how to use a water tunnel to simulate the multiphase flow characteristics of a navigation body under the movement of a maneuvering rudder surface. The traditional water tunnel experiment simulation is mainly based on static simulation, but in fact the motion of the vehicle body and the multiphase flow belong to the unsteady flow with high frequency changes. This mechanism can simulate the unsteady flow characteristics caused by the multiphase flow empennage movement in a small water tunnel experiment section.

[0011] combine figure 1 with figure 2 , the present invention comprises a drive motor 1 for linear motion; an adapter 2 between a linear motor and a swing rod; a swing rod 3; a rectifyi...

Abstract

The invention provides a multiphase flow empennage motion simulation mechanism in a water tunnel experiment. The multiphase flow empennage motion simulation mechanism includes a driving motor which is arranged outside a water tunnel wall face and performs linear motion, an oscillating rod connected through an adapter with an output end of the driving motor which performs linear motion, a sliding block mounted on an end part of the oscillating rod, a pull rod fixedly connected with the sliding block, an empennage rotating rod hinged to an end part of the pull rod and an empennage shaft fixedly connected with an end part of the empennage rotating rod, an empennage is arranged on the empennage shaft, a rectification support structure is arranged within the water tunnel wall face, the oscillating rod is located in the rectification support structure, and the sliding block, the pull rod and the empennage rotating rod are externally provided with a fairing. The multiphase flow empennage motion simulation mechanism in the water tunnel experiment is simple in structure and easy to realize, and simulates a process of vacuole multiphase flow disturbance by empennage motion in a water tunnel by means of the driving motor outside the water tunnel.

Description

technical field [0001] The invention relates to a simulation mechanism, in particular to a multiphase flow empennage motion simulation mechanism in a water tunnel experiment, and belongs to the technical field of multiphase flow control simulation technology for high-speed navigation in water. Background technique [0002] Accurately obtaining the control force technology under the condition of multiphase flow in water is an important key technology to improve and enhance the maneuverability of moving bodies in multiphase flow in water. When the moving body with multiphase flow in water is maneuvering, the empennage of the flying body interacts with the wall of the multiphase flow to generate hydrodynamic force. Effectively obtaining the hydrodynamic parameters is the key point to realize the maneuver control of the vehicle. For the study of the flow characteristics of the motorized tail motion and the force characteristics of the vehicle body, the parameters concerned are ...
