This document discusses hierarchical design models for use in the mechatronic product development process, specifically for synchronous machines. It proposes a hierarchical design process where domain-specific design tasks are not fully integrated at the mechatronic level, but instead models cover different views and levels of detail of a system. Models represent structural, behavioral, and functional knowledge and views of a system. The approach is demonstrated through the design process of synchronous machines.
This document summarizes a research paper that proposes a computer-aided mass balancing method for rotary fixtures on CNC machines. The method uses CAD software to divide the fixture into four quadrants and calculate the mass properties of each quadrant. It then analyzes the mass distribution to determine any imbalances and calculates the necessary counterweights to balance the fixture. This approach allows imbalances to be predicted and addressed during the design phase before manufacturing, which can save costs and improve productivity compared to traditional post-manufacturing balancing methods. The paper presents this proposed computer-aided mass balancing method as applied to the specific case of designing a rotary fixture for machining a TEE body component on a CNC turning center.

IRJET- Optimization of Fink and Howe TrussesIRJET Journal
This document describes research on optimizing the weight of different truss configurations, including double fink, triple fink, modified fink, double Howe, and triple Howe trusses. The optimization problem aims to minimize weight by treating cross-sectional areas as design variables, while satisfying stress, buckling, and deflection constraints. An improved sequential linear programming technique is used to solve the optimization problem. The process involves developing a C program for load calculation, using MATLAB for truss analysis, and applying an optimizer based on improved SLP to determine optimized cross-sectional areas. A parametric study is then carried out by varying span, height, and spacing to identify the most economical truss configuration under the given conditions.

Active vibration control of flexible beam system based on cuckoo search algor...IJECEIAES
A flexible beam is recognized as a lightweight structure that is prone to excessive vibration, resulting in poor performance. Thus, controlling unwanted vibration is necessary to maintain the system’s performance. Therefore, this study presents a technique to suppress undesired vibration in a flexible beam structure by introducing active vibration control (AVC). However, to develop an effective controller, an appropriate flexible beam model must first be obtained. In recent times, one of the best methods employed to model a flexible beam structure is system identification via a swarm intelligence algorithm. In this study, an intelligent algorithm acknowledged as cuckoo search (CS) was acquainted. The capability of the proposed algorithm was verified using three robustness techniques which were correlation test, pole-zero diagrams and mean square error (MSE). The simulation result showed that the CS algorithm achieved superior performance by achieving the lowest MSE of 6.1547x10 -9 , a correlation test between a 95% confidence level and high stability. Next, a proportionalintegral-derivative (PID) controller tuned by the Ziegler-Nichols method was developed using the transfer function accomplished from the CS model. Two types of interference, namely single and multiple sine waves were introduced to validate the effectiveness of the controller. The controller successfully achieved a 30.2 dB of attenuation level for both disturbances.

Basic Concepts
The finite element method
(FEM), or finite element
analysis (FEA), is based on the
idea of building a complicated
object with simple blocks, or,
dividing a complicated object
into small and manageable
pieces. Application of this simple
idea can be found everywhere in
everyday life, as well as in
engineering.

A diversity of specializations under the union of the mechanical engineering
discipline (such as aeronautical, biomechanical, and automotive industries)
commonly use integrated FEM in design and development of their products.
Several modern FEM packages include specific components such as thermal,
electromagnetic, fluid, and structural working environments. In a structural
simulation, FEM helps tremendously in producing stiffness and strength
visualizations and also in minimizing weight, materials, and costs.

FEM allows detailed visualization of where structures bend or twist, and
indicates the distribution of stresses and displacements. FEM software provides
a wide range of simulation options for controlling the complexity of both
modeling and analysis of a system. Similarly, the desired level of accuracy
required and associated computational time requirements can be managed
simultaneously to address most engineering applications. FEM allows entire
designs to be constructed, refined, and optimized before the design is
manufactured.

This powerful design tool has significantly improved both the standard of
engineering designs and the methodology of the design process in many
industrial applications. The introduction of FEM has substantially decreased the
time to take products from concept to the production line. It is primarily through
improved initial prototype designs using FEM that testing and development have
been accelerated. In summary, benefits of FEM include increased accuracy,
enhanced design and better insight into critical design parameters, virtual
prototyping, fewer hardware prototypes, a faster and less expensive design cycle,
increased productivity, and increased revenue.

2.1.1 Direct approach for discrete systems
Direct approach has the following features:
• It applies physical concept (e.g. force equilibrium, energy conservation,
mass conservation, etc.) directly to discretized elements. It is easy in its
physical interpretation.
• It does not need elaborate sophisticated mathematical manipulation or
concept.
• Its applicability is limited to certain problems for which equilibrium or
conservation law can be easily stated in terms of physical quantities one
wants to obtain. In most cases, discretized elements are self-obvious in
the physical sense.

2.1.2 Coordinate Transformation approach
In many cases, one can introduce a local coordinate system associated with
each element in addition to a global coordinate system. A local coordinate
system can be defined in many cases in a self-obvious way inherent to the
element itself. It is much easier to determine the stiffness matrix with
respect to the local coordinate system of an element than with respect to the
global coordinate system. The stiffness matrix with respect to the local
coordinate system is to be transformed to that with respect to the global
coordinate system before the assembly procedure.

2.1.3 Direct approach for Elasticity Problem (plane stress, plane strain)
In this section, we are concerned about an elastic deformation problem in
twodimensional continuous media (therefore, not a discrete system).
2.1.4 Assembly Procedure
The assembly procedure is based on compatibility and conservation law
(e.g. force balance, mass conservation and energy conservation).
2.1.5 Variational Approach in Finite Element Formulation
Differential formulation, physical phenomena can be described in terms
of minimization of total energy (or functional) associated with the
problem, which is called “variational formulation”.

2.1.6 Principle of Minimum Total Potential Energy
There is a very important physical principle to describe a deformation
process of an elastic body, namely Principle of Minimum Total Potential
Energy, which can be summarized as below:
24. Finite Element Method versus Rayleigh-Ritz Method
24
BY: SACHIN CHATURVEDI
One of the historically famous approximate methods for this kind of problem is
Rayleigh-Ritz Method, and the other modern method is the Finite Element
method. Here we will discuss both methods with the comparison in mind.
i) Rayleigh-Ritz Method: This method is very simple and easy to
understand. However, it is not easy to find a family
of trial functions for the entire domain satisfying
the essential boundary conditions when geometry
is complicated.
ii) Finite Element Method: In this case, the shape functions can be found
more easily than the trial functions without
having to worry about satisfying the essential
boundary conditions, which makes FEM much
more useful than Rayleigh-Ritz Method. In this
regard, the Finite Element Method is a
modernized approximation method suitable for
computer environment.

We will discuss the element types, shape functions and discretization in this
section. It is important to be able to select an element type which is most suitable
for the problem of interest, and to determine the shape functions for the chosen
element type. Finally, automatic mesh generation techniques are, in practical
sense, also important to finite element analysis applications.

Note that N (x, y) in our current form is represented in terms of the nodal
coordinates (xi , yi ) and a global coordinate (x, y). One can have a better form in
terms of so-called “Natural Coordinate”, in particular for triangular type of
elements (or “Normalized Coordinate” for a quadrilateral type of elements ).
