Description

Use an object of the simscape.multibody.WorldFrame class to construct a world frame. In a simscape.multibody.Multibody object, the world frame is the global reference frame that is fixed and impervious to any applied forces and moments.

The WorldFrame object has one frame whose axes are orthogonal and arranged based on the right-hand rule. The frame has a corresponding connector called W. Directly connecting another object to the W connector makes that object motionless. A Multibody object may have multiple WorldFrame objects, but all the WorldFrame objects refer to the same world frame.

Examples

  1. Use a simscape.multibody.WorldFrame object to create a world frame.

    world = simscape.multibody.WorldFrame;

  2. Add the WorldFrame object to a simscape.multibody.Multibody object.

    First, use a Multibody object to construct a multibody system. Then, add the WorldFrame object to the multibody system by using the addComponent method.

    mb = simscape.multibody.Multibody;
addComponent(mb,"World",world);

  3. Use a simscape.multibody.Solid object to construct a solid with default values. Then, add the Solid object to the multibody system.

    solid = simscape.multibody.Solid;
addComponent(mb,"Solid",solid);

  4. Connect the Solid object to the world frame by using the connect method.

    connect(mb,"World/W","Solid/R")
