A controlled mass-spring-damper. A controller adjusts the force on the mass to have its position track a command signal. The initial velocity for the mass is 10 meters per second. The controller adjusts the force applied by the Force Source to track the step changes to the input signal.

Two models of a mass-spring-damper, one using Simulink® input/output blocks and one using Simscape™ physical networks.

Two models of a double mass-spring-damper, one using Simulink® input/output blocks and one using Simscape™ physical networks.

A model of a system that connects rotational and translational motion. A summing lever drives a load consisting of a mass, viscous friction, and a spring connected to its joint C. Joint B is suspended on two rotational springs connected to reference point through a wheel and axle and a gear box. Joint A is connected to a torque source through a gear box and a wheel and axle mechanism.

A mass attached to a spring and a viscous damper. The mass is driven by an ideal velocity source through a friction element. The motion profile of the source is selected in such a way that plotting the displacement of the mass against the displacement provided by the source produces a typical hysteresis curve.

Two masses connected by a hard stop. Mass 1 is driven by an Ideal Velocity Source. As the velocity input changes direction, Mass 2 will stay at rest until Mass 1 reaches the other end of the backlash modeled by the Translational Hard Stop. Plotting the displacement of Mass 2 against the displacement of the Mass 1 produces a typical hysteresis curve.

A mechanical rotational system with stick-slip friction. An inertia is connected to a fixed point by spring and damper. The inertia is driven by a velocity source via a stick-slip friction element. The friction element has a difference between the breakaway and the Coulomb frictions, resulting in stick-slip motion of the inertia.

The use of the Simscape™ Lever block in a linkage mechanism. Lever 1 and Lever 4 are first class levers with the fulcrum at the end. Lever 3 is a second class lever with the fulcrum in the middle. Lever 2 is a summing lever driven by the first and the third levers.
