As a junior stress engineer, I was involved with the strength calculation of the generators during different load case scenarios. Next to that, I had to assess the bolt and weld strength of these structures. Most parts of strength calculation were carried out using ANSYS Workbench and the rest were done by hand calculation and Excel spreadsheets. The strength calculations should meet Eurocode, DNV, Noble Denton and VDI2230 As a junior stress engineer, I was involved with the strength calculation of the generators during different load case scenarios.

The floating frame formulation is a well-known method that has a wide variety of applications in flexible multibody dynamics. In terms of formulation, absolute generalized coordinates of a body-fixed frame are used to the rigid body motion whereas, local coordinates describe the flexible behavior. In most cases, the flexibility is small in comparison with rigid body behavior. Hence, it would be more challenging to keep only working with nonlinear finite element techniques. Thus the rule of the floating frame method becomes important. However, one prominent drawback of this method is that it requires Lagrange multipliers for satisfying the kinematic constraint equation. Which are usually highly nonlinear and are expressed in terms of both absolute generalized and local coordinates. In case of considering more complicated structures with large size of both mass and stiffness matrix, the calculation becomes more cumbersome therefore some strategies have to be taken into account to reduce the size of those matrices. Similar to Irons Guyan reduction, Craig-Bampton is one of the common reduction methods that is based on both static interface and internal vibration modes. But, the static Craig-Campton modes can be obtained by setting a unit displacement for one interface point while the rest of the interface points are fixed. Then, the vibrating modes are considered as internal Craig-Bampton modes. As a result, the first goal of this project is to develop a Python program with including both Lagrange multipliers and Craig-Bampton reduction that can be compared with the new method which does not include Lagrange multipliers and SPACAR and ADAMS. Similar to the first goal of this project, a MATLAB program has been developed which includes only a combination of both Lagrange multiplier and Craig-Bampton reduction. The second goal of this project is to consider the analyze the CAE model with this software. Show less

Investigation of the dynamic parameter of the pallet racking As a trainee, I worked in the department of design principles & prototyping at NEDCON. Within three months and under the supervision of Beinte Groen, I investigated the parameters that can affect the dynamic behavior of pallet racking.

Nonlinear Oscillation Analysis By Invariant Manifold Approach (was written in Persian) Nonlinear Oscillations Analysis Of A Multi Degree Of Freedom System with Using Nonlinear Normal Modes Can Be Comprehensive Solution For Analysing Of Nonlinear Structure Dynamics Therefore in This Thesis with Computing Of Nonlinear Normal Modes with Invariant Manifold Method And Utilizing This Method In Oscillations Of A Multi Degree Of Freedom System And A Bending Beam will Be Studied. An Analysis Of Nonlinear Oscillation With Using Invariant manifold it is assumed that degrees of freedom some points are functions of the other points therefore instead of solving of Differential Equations System which presents the motions of System and is also ordered with all degrees of freedoms of system , it can be solved differential equation systems which are ordered with only some degree of freedoms of system which leads to reduce the computational time of differential equation system which presents the motion of system . For studying the dynamical behavior of systems Invariant manifold uses Parametric And Symbolic Relation, therefore, it will be better to comprehend of dynamics of system. Therefore it can be used for various continuous and conservative and non-conservative discrete systems Show less
