Syllabus
Prerequisites: None
Target skills and knowledge: Providing students with the basic technical knowledge (laws, equations, theorems) for modeling mechanical systems. Presenting the chief components for motion generation and power transmission. Investigating the methods for the kinematics and dynamics analysis of machines, with reference, in particular, to planar motion.
Examination methods: Written assessment
Course unit contents: INTRODUCTION: definition of machine and mechanism. Equilibrium, constitutive and congruence equations, simplifying hypotheses. Analysis and synthesis of machines: definition of forward and inverse kinematic analysis, definition of forward and inverse dynamic analysis, kinematic synthesis.

KINEMATICS OF PLANAR LINKAGES: relative motion, kinematic pairs, Grubler equation, loop-closure equations, choice of the independent equations. Assur groups, identification of Assur groups in a mechanism. Loop closure equation Jacobian matrix, numerical iterative solution of position loop closure equations; Newton-Raphson iterative scheme. Solution of position, velocity and acceleration kinematics analysis, velocity and acceleration ratios. Singular configurations. Basic examples: slider-crank mechanism, four-bar linkage, turning-block linkage. Exercises.

DYNAMICS OF PLANAR LINKAGES: essentials of rigid-body mechanics and mass distribution. Principle of virtual work: definition and application to inverse dynamics problems. D’Alambert principle; kinetostatic application of the principle of virtual work. Lagrange equations. Solution of inverse dynamics problems using Newton’s approach, computation of joint reactions. Forward dynamics essentials. Exercises.

POWER TRANSMISSION COMPONENTS: gear trains: definitions, essentials of gears, ordinary and planetary gear trains, Willis equation, computation of the actual gear ratio, efficiency, epicyclic speed-reducers.
