Contenu
The course resumes the basics of rigid body mechanic before introducing less common notions such as shocks theory and vibration analysis. The movement is studied independently of its causes first. The kinematic and the associated torsor are introduced. The course focus and the point before extrapolating the results to generic solids. Mechanical actions and their modelling is presented in order to apply the dynamic notions. Newton’s laws are introduced et allow to link the movement to it cause. Energy is approached as well as the basics of shock theory, which is at the limit of the rigid body hypothesis. Finally, the vibration analysis and it matrix formalism is presented and applied at two degress of freedom systems. Exercises are done after each notion to put into practice formula and method introduced in the course.
