MECHANICAL DESIGN
What is Mechanical Design?
Mechanical design is developing a system, component, or process within the limits of manufacturability to meet desired needs. Mechanical designers produce machines, products, and new technologies. CAD software support this process. Mechanical designers need to have knowledge of production quality and standards depending on the industry and products for which they are designing. Knowledge of simple limit tolerance techniques or geometric dimensioning and tolerance may be required.
About Mechanical Design
Among some of the largest industries using mechanical design are aerospace and defense. A product requiring continuous mechanical design and development, which is successful in industrial design but fails to support the necessary criteria in mechanical design, is only visually impressive. At the same time, it is the study of reflecting the pre-planned scenarios on the product in order for the product to pass through the production method, working logic, assembly conditions, possible tests, and verifications. Mechanical design contains the fundamental dynamics of mechanical engineering. It is an interdisciplinary study subject that includes the concepts of force, materials, machine elements, mechanism technique, and kinematics. Simulation and analysis studies are carried out in order to predict problems before production during mechanical design. This practice is called “virtual prototyping” The conditions -under which the product/system will work- are prepared as a scenario in the simulation program, and a virtual test is performed. According to the results, the design is subject to the necessary revisions.
Advantages of Mechanical Design at GMKA
1. With a good knowledge of materials, machinery technique, we can professionally design moving, interlocking, working systems.
2. We plan the mechanical design with the production method.
3. With simulation and kinematic analysis, we examine the working performance of the design under real conditions is examined in a computer environment and make the necessary revisions quickly.
4. In addition, we analyze the mechanical design, the load it will be exposed to during its working life and the necessary effort in a computer environment.
5. We provide the advantage of working with different types of materials.
• A powerful tool in competition
• The impact of the design
• The advantage of professional support
What is Reverse Engineering?
Reverse engineering has various meanings depending on the occupational groups. For the manufacturing sector, it refers to the process of creating CAD data for a manufactured product using digitization systems. In other words, it is the discovery of engineering secrets.
How does reverse engineering work in GMKA Defense?
Optical and laser scanning systems are generally used for reverse engineering. Firstly the target data of the part is obtained with the scanning system. Sections are taken from the obtained data using software. Sketches are created from the sections taken. These sketches are finalized by creating solids or surfaces.
• Since solid surfaces can be obtained from sketches with draft-based modeling and parametric modeling, the changes made are reflected in the entire design.
• Data can be created easily with fast surface modeling. Editing is done on the scan data (such as closing gaps, cleaning deformations, regulating the number of polygons, smoothing or sharpening polygon transitions).
We choose the most suitable method according to part geometry, precision, cost, or application. The difference between these two processes is that one of them is controlled data, and the other is data generated according to the software’s algorithm.
Application Areas of Reverse Engineering
• If the original manufacturer of a product is no longer producing the product, producing 2D/3D drawings of it,
• Using the original design to build on when we find it inadequate,
• When the original design data is lost or not available,
• Fully revealing the good and bad features of competitor products,
• Creating data to perform mechanical analysis on competitor products in the development of new products,
• Discovering new ways to improve product performance and properties,
• Analyzing deformation and displacement of worn parts,
• Archiving studies.
• Fast results
• Precision
• Modeling complex geometries
• Low cost

Due to dynamic combat conditions, the use of electronic mission systems in today’s military vehicles is increasing. In a typical combat vehicle, many sub-systems such as vehicle electronics, weapon systems, communication, reconnaissance-surveillance, countermeasures, situational awareness, etc. are expected to work together. This situation necessitates the diversity, reliability and long-term autonomous (independent of the vehicle engine) use of the energy sources in the vehicle.
