Description
Technical Field
The invention belongs to the field of driving simulation, and particularly relates to a friction type simulation rudder device with adjustable damping for sailing ship driving training.
Background
Sailing is a water sport. The sportsman operates the equipment such as sail and tiller, etc., and utilizes natural wind force to make sailing boat advance, and in the course of running, it fully utilizes the influence of wind and wave. When driving simulating sailing boat movements, three aspects are mainly considered, namely the control of the sails, the rudders and the weight distribution, respectively. The sportsman changes the windward area and the direction of the sail by pulling the sail rope, provides sailing power for sailing, and keeps the balance of the sailing boat under the action of the direction stabilizing plate and the weight distribution of the sportsman. The rudder of a small sailing boat is generally arranged at the stern and has a tiller and a lever attached to the rudder stock, where the rudder blade is a wing-like or flat structure with a small aspect ratio. The force of the water flow on the rudder blade can be divided into a rudder resistance along the fluid flow direction and a rudder lift perpendicular to the fluid flow direction. An athlete rotates a rudder stock through an operation rod, an included angle between a rudder blade and a main axis of a ship body is changed, so that the lift force and the resistance of a rudder are changed, the lift force of the rudder generates a steering torque for midships of the ship, and the sailing ship is steered.
