Prerequisites:
|
Mathematical Analysis 1
Numerical Analysis
Engineering Drafting
Physics
Topics in Linear Algebra and Geometry |
Target skills and knowledge:
|
Theoretical and computational tools to solve kinematics and dynamics and synthesis of planar mechanical systems. |
Examination methods:
|
The exam includes two mandatory activities: in-course homework assignments and final written exam. The homework assignments contribute 5/30 of the final grade while the written exam contributes 25/30. The assignments require to solve numerical exercises using Matlab and a commercial multibody SW. The written exam consists in solving two numerical exercises and answering three open questions in max 2h30; the use of lecture notes and/or textbooks is not permitted. The exam may be carried out either in Italian or in English, according to the student’s preference. |
Assessment criteria:
|
ASSIGNMENTS
• correctness of the final solution
• clarity and synthesis in the presentation of the results
WRITTEN EXAM
• correttezza della soluzione finale
• chiarezza e sintesi nella presentazione dei risultati
• knowledge and understanding of the course contents
• ability to illustrate the topics in a clear and concise way
• appropriateness of use of technical terminology |
Course unit contents:
|
Kinematics: degrees of freedom, main planar joints, rigid body kinematics, rotation matrices, velocity centers, analysis of open and closed-kinematic chain systems, analysis of cam systems, gear trains (ordinary and planetary), car differential, kinematic design for the generation of rigid motion, trajectories and functions, cam design.
Dynamics: elements of tribology (sliding and rolling friction, wear), equations of motion (energy approach and newtonian approaches) for single degree of freedom systems, dynamic equivalence for rigid bodies, efficiency in mechanical systems, rotordynamics (static and dynamic imbalances, vibration modes, critical velocities, self-balancing), balancing of the slider crank, motion regulation in mechanical systems.
Mechanical vibrations: modal analysis (mode frequency and shape), forced response, vibration isolation.
Essentials of control of linear mechanical systems: block diagrams, step response, ramp response, harmonic response, feedback control. |
Planned learning activities and teaching methods:
|
Lectures in class (75% of the course) and in the computation lab (25% of the course) for numerical simulation activities using Matlab and a commercial SW for the kinematic and dynamic analysis of planar mechanical systems; individual assignments. |
Additional notes about suggested reading:
|
Lecture notes, matlab scripts on moodle, reference books. |
