Modern turbine blades and vanes possess very complex internal geometry. As a result of this complexity the design through conventional means, such as a Computer Aided Design (CAD) package, can take a large portion of the allocated time, preventing thorough testing and optimization. The aim of this thesis is to produce a parametric design methodology that can be used to create turbine blade and vane geometry from designer-specified parameters. This work includes a thorough study of the current blade and vane design process, an in-depth analysis of the most commonly used geometry represention methodologies, as well as a review of existing works on the subject. The research code, based on the created design methodology, was tested on the existing blade and vane design schemes. The result of this comparison is presented. The developed methodology can be used to shorten the design time necessary to produce the blade and vane geometry, thereby increasing the time available for analysis and optimization.

This article describes a sophisticated determination and presentation of a workspace volume for a delta robot, with consideration of its kinematic behavior. With the help of theoretical equations, optimization is performed with the aid of the stiffness and dexterity analysis. Theoretical substructure is coded in Matlab and three-dimensional (3D) data for delta robot are developed in computer-aided design (CAD) environment. In later stages of the project, both 3D and theoretical data are linked together and thus, with the changing design parameter of the robot itself, the Solidworks CAD output adapts and regenerates output with a new set of parameters. To achieve an optimum workspace volume with predefined parameters, a different set of robot parameters are iterated through design optimization in Matlab, and the delta robot design is finalized and illustrated in the 3D CAD environment, Solidworks. This study provides a technical solution to accomplish a generic delta robot with optimized workspace volume.

Instrumentation utilizing the thermoelastic effect has become established in recent years as an important tool for experimental stress analysis. This instrumentation provides full field stress data in a digitized form that can be integrated with computer aided design methods for experimental optimization and validation of designs. More recently the same full field data acquisition techniques have been applied to vibration measurements. As a result stress and vibration data can be obtained from the same experimental set-up. The paper describes theoretical aspects of the thermoelastic effect upon which the stress measurements are based. It goes on to show how laser Doppler interferometric techniques can be incorporated into stress measuring instrumentation. Results from typical aerospace components are used to illustrate applications of commercially available instrumentation (Fig. 1).

A successful product designer must combine natural creativity with the systematic use of structured design methodology and modern computer-aided design tools. Practice without proper instruction and formal guidance fails to recognize the vast knowledge of the design process developed by successful professionals. However, designing a product solely by theory without the experience derived from practice is ineffective because many subtleties and exceptions are learned by working on actual design project. In this paper, the authors discuss how formal lectures on product design and development methodology can be effectively combined with a hands-on design project leading to viable solutions by novice engineering students to open-ended problems.

3D digital models of the upper limb anatomy represent the starting point for the design process of bespoke devices, such as orthoses and prostheses, which can be modeled on the actual patient’s anatomy by using CAD (Computer Aided Design) tools. The ongoing research on optical scanning methodologies has allowed the development of technologies that allow the surface reconstruction of the upper limb anatomy through procedures characterized by minimum discomfort for the patient. However, the 3D optical scanning of upper limbs is a complex task that requires solving problematic aspects, such as the difficulty of keeping the hand in a stable position and the presence of artefacts due to involuntary movements. Scientific literature, indeed, investigated different approaches in this regard by either integrating commercial devices, to create customized sensor architectures, or by developing innovative 3D acquisition techniques. The present work is aimed at presenting an overview of the state of the art of optical technologies and sensor architectures for the surface acquisition of upper limb anatomies. The review analyzes the working principles at the basis of existing devices and proposes a categorization of the approaches based on handling, pre/post-processing effort, and potentialities in real-time scanning. An in-depth analysis of strengths and weaknesses of the approaches proposed by the research community is also provided to give valuable support in selecting the most appropriate solution for the specific application to be addressed.

The effort of human creativity in the field of hydraulics in overcoming the problem of irrigation, one of which is using floodgates. The discharge from the floodgates needs to be adjusted to the water needs of the plant. However, due to the long design process, the computer aided design of sluice on tertiary irrigation channels is needed in order to be able to set the optimum dimensions and output discharges of crops water needs with fast design time. The tool used in the form of a computer device with Ms Excel and AutoCAD software and materials used were secondary data, that is water needs of local varieties of rice plants in Mangkung, Rambitan, NTB on an area of 50 ha. The data’s then calculated and the largest discharge is 0.12 m3/s with plant evapotranspiration of 5.10 mm/day and 6.43 mm/day of effective rainfall, meanwhile the smallest is 0.02 m3/s with plant evapotranspiration of 3.17 mm/day and 3.47 mm/day of effective rainfall. The dimensions of the steel sluice gates obtained are width of sluice gate 0.40 m, height of sluice gate is 0.80 m with an estimated cost of making Rp 7,547,000 per one sluice. The dimensions of the GFRP sliding sluice gates are width of sluice gate 0.50 m, height of sluice gate is 0.75 m with an estimated construction cost of Rp 7,547,000 per one sluice.
