The invention provides a rudder for motion control, and relates to the field of rudders for motion control. The rudder comprises a base, a rudder blade, an elastic structure and a shape memory alloy wire, wherein the elastic structure is connected between the base and the rudder blade; the base is provided with a first fixing point, the rudder blade is provided with a second fixing point, and the shape memory alloy wire is connected between the first fixing point and the second fixing point in a traction mode. The shape memory alloy wire is a two-way shape memory alloy wire, and the end part of the shape memory alloy wire is also provided with a power connection end connected with a power supply; the rudder blade has a deflection state and a middle state, and when the rudder blade is powered on, the shape memory alloy wire is heated to generate contraction deformation and overcomes the elastic force of the elastic structure to enable the rudder blade to deflect towards one side of the base; during power failure, the shape memory alloy wire is cooled to generate stretching deformation, and the rudder blade is restored to the middle state under the elasticity of the elastic structure. Through cooperation of the shape memory alloy wire and the elastic structure, the purpose of controlling the position of the rudder blade is achieved.
本发明提供了一种用于运动控制的方向舵,涉及用于运动控制的方向舵领域。该方向舵包括基座、舵叶、弹性结构和形状记忆合金丝,弹性结构连接于基座与舵叶之间;基座设有第一固定点,舵叶设有第二固定点,形状记忆合金丝牵拉连接于第一固定点与第二固定点之间;形状记忆合金丝为双程形状记忆合金丝,形状记忆合金丝的端部还设有与电源相连的接电端;舵叶具有偏转状态和中间状态,在通电时,形状记忆合金丝发热产生收缩变形,并克服弹性结构的弹力使舵叶朝基座的一侧偏转运动;在断电时,形状记忆合金丝降温产生伸展变形,并在弹性结构的弹力下使舵叶恢复至中间状态。通过形状记忆合金丝和弹性结构的配合,实现了对舵叶位置控制的目的。
