OBJECTIVE: To create a suspension template using the template builder in ADAMS Car and run a Kinematic Analysis on it.   THEORY: MSC ADAMS is one of the most powerful tools in Multibody Dynamics, which focuses more on automobiles, especially on the suspension design. ADAMS Car provides us with a Template builder option,…
