Translational Mechanical System Example 2 | 2D Freedom | Calculations & Simulink/Simscape Simulation

In this video, we will determine transfer functions in a translational mechanical system having two degrees of freedom. The complete system is composed of two masses, two dampers, and two spring. This is a model of car mass on top of a shock absorber and tire.

We will discuss how we can setup the differential equation for the system and from there determine the transfer function. Step by step, we will carry out the calculations. Using simulations in MATLAB and Simulink with Simscape, we will check our calculations and thereby verify that the element values are correct.
