Mechanical systems are generally classified as open-loop and closed-loop systems according to their architecture. The open-loop systems are driven by externally applied forces and moments with preprogrammed dependence on time. The closed-loop systems apply the feedback control principle based on sensing system motion parameters. Mechanical or robotic system architecture typically includes simple mechanisms executing either rectilinear or rotational motion.
The main objective of this experimental work and assignment is to understand behavior and to learn the basic dynamical properties of a simple mass-spring-damper system (ECP-210) under the action of externally applied force. The external driving force can be formed as a predefined function of time allowing you to understand different aspects of their dynamics and compare the observations with related mathematical models. You will be asked to draw conclusions from your experimental study and confirm them using theoretical analysis.
