在工程技术上经常遇到急速转动着的物体,可以统称之为陀螺。如要使这种物体的转轴改变方向会遇到一种与转轴运动方向垂直的反抗力矩,称为陀螺力矩,这和静止的物体是完全不同的。这种陀螺力矩常需要在工程设计中考虑到,例如谷种涡轮的按装问题等。又对于一个转轴能向任何方向转动的陀螺,外加力矩所引起的不是沿力知方向的角加速度,而是垂直于力矩方向的、一个等速转动,称为陀螺的进动,这也是和静止的物体是不同
In engineering often encountered rapid rotation of the object, can be collectively referred to as the gyro. If you want to change the direction of the axis of rotation of such objects will encounter a kind of reaction torque perpendicular to the direction of movement of the shaft, called the gyroscopic moment, which is completely different from a stationary object. Such gyroscopic torque often need to be taken into account in engineering design, such as grain turbine installation problems. Also for a spindle can rotate in any direction of the top of the gyroscope, the applied torque is not caused by the angular acceleration along the direction of knowledge, but perpendicular to the direction of torque, a constant speed rotation, called gyroscope precession, which is also static The objects are different
