Rotational Spring
The ideal spring in mechanical rotational systems.
Description
The Rotational Spring unit represents an ideal mechanical rotational spring described by the following equations:
Where:
|
Torque transmitted through the spring |
|
Coefficient of elasticity |
|
Relative displacement (spring deformation) |
|
Initial position (spring displacement) |
|
Absolute angular positions of ports R and C respectively |
|
Relative angular velocity |
|
Time |
The positive block direction is from port R to port C. This means that the torque is positive when it acts in the direction from R to C.
Ports
R - rod
`rotational mechanics
A mechanical port of rotation corresponding to a shaft, that is, a moving body.
C is the body
`rotational mechanics
A mechanical port of rotation corresponding to the case, i.e. a fixed body.
Parameters

Initial value of rotational velocity, rad/s - initial value of angular velocity
0.0 (by default)
Initial value of angular velocity.
Initial value of torque, N*m - initial value of torque
0.0 (By default)
Initial value of torque.
Initial value of deformation, rad - initial value of deformation
0.0 (By default)
