The Participation of Students in the Transfer of Technology with Regard to Probabilistic Design Methodology.
Landon C. Onyebueke, Chinyere Onwubiko Tennessee State University
The variability and complexity of human needs and demands always lead to advancement in technology, new discoveries and hence, the need for technology transfer. Probabilistic Design Methodology (PDM) is a computational simulation method based on simple engineering models. It is concerned with the probability of non-failure performance of structures or machine elements. This technology has been successfully applied to various loading conditions encountered during space flights. However, this technology is yet to be accepted in the industries. This paper uses PDM to demonstrate the role of students in the transfer of technology. Included in the paper are overview of PDM, the different stages that are necessary in preparing students for effective technology transfer. Projects carried out by engineering students at Tennessee State University are used to illustrate the features of PDM and how students can be used as a means for the transfer of the technology to industries.
The effectiveness of any new technology is reflected in its usefulness. Its popularity depends on the application and success in transferring the technology. One of the most important areas in engineering that requires precision and accuracy is engineering design. Engineering design mostly depended on deterministic design methodology. As a result, deterministic design has reached a very high level of sophistication to the point that modern computational techniques make it possible to determine the stresses, strain and displacement of complex structures. In deterministic design the contingency of failure is totally discounted, which leads to the choice of a high factor of safety. Unfortunately, the design of structures are really clouded with uncertainties. The fact that deterministic design methodology does not account for uncertainties in a direct manner makes it impossible to know when a system is over-designed or vice versa. This fact has led to a more focus on PDM. PDM is increasing in popularity among researchers due to the fact that it takes into consideration reliability, optimization, cost parameters and the sensitivity of design parameters. Deterministic method, which is the most common design method in the design of machine elements lacks most of these features. Probabilistic design approach is concerned with the probability of non-failure performance of structures or machine elements. It is much more useful in situations where the design is characterized by complex geometry, possibility of catastrophic failure or sensitive loads and material properties. The PDM normally requires a lot of computation but the advancement in technology has reduced the rigors that normally accompany
