To shortly describe what was I learned and what do I know, I have divided my study into three parts:
1. Dynamics: Create equations of motion that describe given problem by Lagrangian or Newtonian formalism. Than compute natural frequencies and mode shapes or simulate the model behaviour under variety of excitations. Finally to interpret the results and optimalize the mass inertia stiffness or damping parameters with respect to requirements. We were using Matlab and Labview for numerical simulations.
2. Mechanisms: Propose and optimalize the multi-body systems with respect to requirements. Two dimensional problems are handled by vector algebra with corresponding loop equations and three dimensional problems are solved by matrix algebra. Both problems lead to nonlinear algebraic equations solved in suitable software. We have used MSC.adams which handles kinematics as well as dynamics of multi-body systems.
3. Strength and elasticity: Simple problems can be handled by analytical approach, but complex geometries require finite elements approach. To get the deeper understanding what is going on in the FEM softwares, cantilevered beam (based on Ansys beam3 element) was programmed in Matlab. Static, Modal ,Harmonic and Transient analysis were performed and results were compared with results from Ansys.
