To set an accurate engine mount durability specification it is important to know actual 3 axis movement of the engine mount on the proving grounds. Due to the size of test equipment and the limited sp....
In the automobile industry, the reliability and predictive capabilities of computer models for a dynamic system need to be assessed quantitatively. Quantitative validation allows engineers to assess a....
Electric & Electronic testing and simulation techniques are becoming widely used in automotive field to ensure higher quality and cope with dramatic shrink in projects schedule and budget. These techn....
Computer Aided Engineering (CAE) has become a vital tool for product development in automotive industry. Various computer models for occupant restraint systems are developed. The models simulate the v....
The mechanical behavior of rubber-like materials is usually characterized by a strain energy density function, w. The parameters defining the density function, w, are considered as material parameters....
Seals are commonly made by using o-rings in many liquid and gas filled system. Since the introduction of mini-concentric fuel pressure regulators mounted on fuel rails, issues have arisen related to a....
Predicting the optimum performance parameters of an automotive cyclone particle separator (separation efficiency and pressure drop) using computational fluid dynamics by varying its geometrical parame....
This paper presents an approach to product design and development based on function failure avoidance, using of series of well known engineering tools including Function Fault Tree Analysis, P-Diagram....
A DFSS study identified a new mechanism for clamp load loss in aluminum threads due to thermal cycling. In bolted joints tightened to yield, the difference in thermal expansion between the aluminum an....
After era of productivity and quality, creativity is considered as an important issue to become winner and build paradigm in the global market. In the past, brainstorming based on inspiration and expe....
Dimensional variation analysis is a critical step of the dimensional management process for understanding the predicted dimensional variation from manufacturing process. Through analysis, product and ....
The T-method is a technique developed by Genichi Taguchi to calculate an overall prediction based on the signal-to-noise ratio without the use of Gram-Schmidt orthogonalization. The Taguchi methods, a....
The air intake system consists of air cleaner, air intake hose, air duct and several resonators. Its function is generally to maximize the engine power and minimize the air induction noise. However, t....
Many efficient modeling methods have been developed for analyzing the effects of component-level variations and uncertainties on the system-level response of complex structures. However, relatively li....
Operation & support costs for military weapon systems accounted for approximately 3/5th of the $500B Department of Defense budget in 2006. In an effort to ensure readiness and decrease these costs for....
In this article, the authors illustrate the benefits of axiomatic design (AD) for robust optimization and how to integrate axiomatic design into a total robust design process. Similar to traditional r....
This study shows how to apply the principles of Axiomatic Design to develop a system for cutting parameter selection for milling-one of the widely used material removal processes. The attention is giv....
The concept of complexity is an essential constituent of axiomatic design and axiomatic quality. A reciprocal transformation is used to compute quality loss for larger-the-better performance character....
This paper is a discussion of topics presented by the author at the Panel Session “Evaluation of Studies on Non-Deterministic Approaches (NDA) for Complex Systems” at the 2007 SAE World Congress. The ....
Accounting for more than 90% of the molecules and more than 75% of the mass [1], hydrogen is the most abundant element in the universe. Due to the small molecule size and high buoyancy, it is not avai....
