Precise Mechanics I
FSI-TP1Acad. year: 2018/2019
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.
