Syllabus
Prerequisites: Knowledge and basic skills of physics (kinematics and dynamics of a point and of a rigid body), of mathematical analysis and linear algebra.
Target skills and knowledge: The course aims to provide students with the fundamental technical knowledge (laws, equations, theorems) for mechanical modeling. The course allows acquiring knowledge on the main components for motion generation and power transmission.
The course provides methodologies and tools for solving the kinematic and dynamic analysis of machines, with reference, in particular, to planar motion.
Examination methods: The assessment of knowledge and abilities is carried out through a written assessment divided into two parts done in the same day:
- in the first part, through at least two separate open-ended questions, the student's knowledge of the course topics is ascertained,
- in the second part, through the solution of a practical problem (exercise), the abilities related to mechanical modeling and the computational capabilities are ascertained.
Assessment criteria: The evaluation criteria by which the knowledge and abilities acquired will be verified are:
- the completeness of the theoretical knowledge acquired on the course topics;
- the level of autonomy acquired in the interpretation and solution of mechanical of machine problems.
- proved ability to apply theoretical knowledge to the development of kinematic and dynamic models of mechanisms;
- the presentation capabilities and the rigorousness in the discussion of the issues discussed
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. The instantaneous center of rotation. 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. Projected inertia. Solution of inverse dynamics problems using Newton’s approach, computation of joint reactions. Forward dynamics essentials. Exercises.

KINEMATICS, DYNAMICS AND SYNTESIS OF CAMS: mechanisms with planar cams: classification, definition of the pressure angle, kinematics analysis and synthesis (basics), introduction to motion profiles and to trajectory planning, kinetostatic analysis.

POWER TRANSMISSION COMPONENTS: gear trains: definitions, essentials of gears, ordinary and planetary gear trains, Willis equation, computation of the actual gear ratio, epicyclic speed-reducers. Power transmission with flexible components (ropes, chains, belts). Basics of other power transmission mechanisms (leadscrew, rack and pinion). Lagrangian dynamic models for single-degree-of-freedom mechanisms with power transmissions. Mechanical efficiency of power transmissions. Exercises.
Planned learning activities and teaching methods: - Lectures also with the support of computer material (power point and pdf files prepared by the lecturer, plots and elaborations in Matlab, videos and images, industrial catalogs)
- Exercises developed on the blackboard
Additional notes about suggested reading: All teaching material (lecture notes, exercises, exam topics) is made available by the "moodle" platform (https://elearning.unipd.it/dtg/)
