Aims of the course unit:
The aim of the subject is to familiarize students with the solution of mechanisms movements within instruments and devices of precise mechanics with an optimal use of computers.
Learning outcomes and competences:
The course enables students to acquire knowledge necessary for solving problems connected with movements within instruments and devices of precise mechanics with respect to kinematic and dynamic parameters of the system.
Prerequisites:
Equations of motion, matrices, functions, basic programming skills.
Course contents:
The course “Precise Mechanics I” familiarizes students with solution of opened and closed kinematic chains used in equipments of precision mechanics using matrix methods. Special attention is paid to analysis of precision and sensibility of mechanisms. Lagrange equations of second type with multiplicators are used to solve equipment dynamics. MATLAB software is used to solve selected problems.
