Springs are elements that exert force that increases in accordance with their distortion. Springs have a given length in their state of rest (a given rotation for a angular springs) in which no force is exerted. As soon as a spring’s length or rotation is altered a force is exerted that attempts to return the spring to its state of rest. A springing motion occurs as a result of the mass inertia of an object linked to the spring that causes the spring to extend or compress beyond its state of rest.

弹簧是施加力的元件，随着扭曲程度的增加而增加。弹簧在静止状态下有一定的长度(角弹簧的一定旋转角度) ，在静止状态下没有外力作用。一旦弹簧的长度或旋转发生改变，就会产生一个力，试图使弹簧恢复到静止状态。弹簧的运动是由与弹簧相连的物体的质量惯性引起的，这种惯性使弹簧超过静止状态而伸展或压缩。

The Spring object offers two types of springs:

Spring 对象提供两种类型的弹簧:

• Linear 线性
• Angular (rotational) 角度(旋转)

The Spring type will be displayed in the Viewport.

Spring 类型将在 Viewport 显示。

Note that Springs exert force on the linked objects but do not hold these in place. Additional Connectors are required for this. In the example above, these would be:

请注意，弹簧对相连的物体施加力，但不能将它们固定在合适的位置。这需要附加的连接器。在上面的例子中，它们是:

• Linear: 线性:Type 类型 = Slider 滑子
• Angular: 角:Type 类型 = Hinge 铰链
