Instance: Mass-Spring-Damper System

System Explanation

An excellent instance of a second-order dynamic model is a mass-spring-damper model. Generally, a spring with stiffness kkk, a damper with damping coefficient bbb, and a mass mmm are encompassed.

For this model, the equation of motion is: mx¨+bx˙+kx=F(t)m \ddot{x} + b \dot{x} + k x = F(t)mx¨+bx˙+kx=F(t) where:

• xxx indicates the displacement,
• x˙\dot{x}x˙ specifies the velocity,
• x¨\ddot{x}x¨ denotes the acceleration,
• F(t)F(t)F(t) is described as the external force that is implemented to the mass.

• Typically, the output of the second Integrator must be linked to the Scope block.
• As a means to create the damping and spring forces, it is significant to join the Gain blocks to the suitable inputs of the Sum block.

5. Set Parameters:

• The parameters of the Step block should be initialized such as Final Value = 1, Step Time = 1, Initial Value = 0.
• With values such as k/mk/mk/m, 1/m1/m1/m, and b/mb/mb/m, we plan to set up the Gain blocks.
• Whenever required, our team initializes the preliminary conditions of the Integrator block.

6. Set Simulation Parameters:
