Scientific Challenge

AbstractThe global megatrends of digitization and individualization substantially affect manufacturing enterprises. Assembly workers are exposed to increased process complexity resulting in physical and cognitive workload. Worker guidance systems (WGS) are used to overcome this challenge through output of information regarding what should be done, how it should be done and why it should be done. An unsolved scientific challenge in this context is efficient information supply of WGS. Information such as worker’s instruction texts, pictures or 3D representations are created by employees of the work preparation department and transferred to the WGS. Manual information supply is a time-consuming and complex process, which requires a high (non-value-adding) effort as well as comprehensive knowledge in handling 3D CAD modelling and software programming. This paper presents a novel approach to reduce the required manual effort in information supply process. A knowledge-based model is proposed that enables an automated information supply of WGS in smart assembly environment by means of algorithms and self-learning expert systems, which pursues a holistic and consistent approach without media breaks. The automated approach assists employees of work preparation department, which means they can concentrate on their essential core competencies instead of being busy, for example, creating assembly plans, instruction texts or pictures for individual WGS. Finally, the technical implementation as a software-based proof-of-concept demonstrator and sub-sequent integration into the IT environment of TU Wien Pilot Factory Industry 4.0 is outlined.

This paper details a thermo-fluid model of the cylinder-piston-valve assembly of a pneumatic rodding boiler port cleaner. The relationship among the governing parameters is established. Model-predicted results are presented graphically and compared with experimental curves to verify the validity of the model. Small exit orifice areas offer a better cushioning effect. Numerical simulations show that the piston velocity increases with supply pressure and the weight of the piston, decreases with orifice area and is independent of the inclination angle of the device.

Reverse engineering has become the one of the most relevant concepts in modern design doctrines. Advances in technology demand shorter lead time in the overall product development stage, especially in the automobile sector. Hence as a study in reverse engineering, the author has reverse engineered a twin tube shock absorber. The process involved the obtaining of subassemblies of the damper mechanism to generate a 3D CAD model of the damper in PTC CREO 2.0. The model was used to conduct static structural and CFD analysis of the same using ANSYS 15.0 Workbench. The data obtained was used as the datum for the design modifications and performance enhancement of the part. It was seen that the design of the piston valve was optimum hence modifications to the base valve were done. Following the generation of the datum, similar analyses were conducted on the modified assemblies. The results were compared to the datum for the selection of the most appropriate design. Four designs are analyzed and compared with the datum and the set with four orifices in the valve disk was found to be optimum.

Creative thinking is an essential part of learning for sustainability, as recent studies indicate. Creativity enables the engineer to find solutions for the design of a new product or for the improvement of one already designed, to make it more sustainable. However, currently, engineering education does not usually assess academic performance in terms of creativity, and although interest in creative processes in engineering is growing, its implementation in the classroom is still scarce. In the present study, a creativity workshop was conducted in order to find multiple solutions to the problem posed, in accordance with divergent thinking. The workshop was based on a 3D CAD modelling activity, and the students needed to give different 3D design solutions starting from a two-dimensional shape. The participants were 72 engineering students from the engineering graphics subject in the degree in agricultural engineering and rural areas. Nine different creative components were evaluated. That way, not only was a generic measure of creativity obtained, but it was also possible to know the evolution of the student after the workshop for each of the components of creativity separately. The results of the workshop confirmed that creativity could be enhanced, and therefore, the learning process for sustainability can be improved in engineering.

Brake Drum

A Brake drum is specialized brake that uses the concept of friction to decelerate the vehicle speed. The deceleration is achieved by the assistance of the friction generated by a set of brake shoes or pad, when operator presses against a rotating brake drum. The material generally preferred for making the brake drum is grey cast iron or vermicular cast iron. The drum brake is highly efficient for hand brake and service brake applications. During the operation of drum brake excessive heating of brake drum may occur. This excessive heating occurs due to repeated or frequent contact of the brake shoes against the drum. This causes the drum to crack, oversize, extreme wear, out of round drums and also leads to vibration which while braking will leads to reduced brake drum life and braking efficiency. The Un-laden weight of the vehicle will result in increased fuel consumption, reduced payload and ride handling characteristics. The objective of the paper is to improve the thermal characteristics by incorporating fins in the brake drum and to reduce the un-laden weight of the vehicle by changing the rib thickness, wall thickness and base flange thickness. The design is done by using 3D CAD Modelling software and Hexahedral finite element model prepared by using CAE pre-processing software and Stiffness analysis. Design iterations are carried out by using Linear/Non-linear Finite Element Solvers, Stress Displacement and Temperature is post-processed for design validation. Optimized design solution obtained based on the comparison study between the iteration with rib thickness 75 mm, star shaped removal and wall thickness 17 mm has been chosen. 1.8Kg of weight is being reduced from the brake drum including fins. Keywords: Drum Brake, 3D CAD Modelling, Para Metric Matrix, Structural Analysis, Fins.
