To investigate how fatigue damage is accumulated, experimental work was conducted in the present study. Aside from the regular tensile test, the experiment includes constant-amplitude, two-stress-leve....
In the automotive industry, a lot of attention has been paid to the effort required for opening/closing the doors, and for a good reason. The door closing and opening effort creates an impression in t....
In this paper, the Axiomatic Quality method is introduced in terms of three sequential phases: The Customer Attributes-to-FRs mapping phase, the Conceptual design For Capability (CDFC) phase and the O....
One of the goals of designing engineering systems is to maximize the system's reliability. A reliable system must satisfy its functional requirements without failure throughout its intended lifecycle.....
Avoiding failure modes is the ultimate goal of reliability engineering [1, 2]. Design for Six Sigma [3] coupled with Transfer Function [4] analysis is a process that can help to achieve this goal at e....
The concept of product or system function is considered as described in the Taguchi System of Quality Engineering. The importance of transfer functions is also discussed and a review of conventional v....
Deficiencies in understanding port flow have created an elongated design process involving computer automated engineering tools and empirical results. Analytical flow models could solve the problem ho....
Design for Six Sigma (DFSS) has evolved as a worthy predecessor to the application of Six-Sigma principles to production, process control, and quality. At Lawrence Livermore National Laboratory (LLNL)....
The U.S. Army's Stryker vehicle was in need of a design upgrade on one of its components. A newly designed hydraulic reservoir was tested and analyzed on a component level to gain acceptance to be use....
Comparing OEM vehicle launch requirements to the US Army Materiel Release procedures can be confusing at times. If done well, the work team could achieve minimal disruption while completing requiremen....
Existing methods for design optimization under uncertainty assume that a high level of information is available, typically in the form of data. In reality, however, insufficient data prevents correct ....
Occupant packaging practice relies on statistical models codified in SAE practices, such as the SAE J941 eyellipse, and virtual human figure models representing individual occupants. The current packa....
The purpose of this paper is to improve the understanding of the advantages of a non-contact electronic throttle control (ETC) air control valve position sensor over the potentiometer technology of co....
One of the main threats to military vehicles originates from landmine blasts. In order to improve the survivability of the occupants it is important to design a military vehicle for increased occupant....
Many previous studies on spot weld were focused on how to simulate the rapture behavior with high accuracy at a single simulation under deterministic analysis conditions. In this paper, a stochastic a....
Response surface methods have been widely used in robust design for reducing turn-around time and improving quality. That is, from a given set of CAE data (design-of-experiments results), many differe....
Electric Active Stabilizer (EAS) system, that is capable of having a good balance between roll angle control and comfortable driving, has been developed. The EAS system can automatically control a rol....
This paper presents a pioneer work and first time application of Multi Objective Robust Optimization to analytically improve Idle Shake Performance. The method is developed to obtain a robust design w....
Axle cover pan bolted joint sealing with a fiber composition gasket material can be challenging to achieve leak-free sealing. A project was conducted to optimize a stamped steel cover pan/fiber compos....
Robust design methods are becoming widely adopted in automotive industries because of their cost- and time-efficiency for quality improvement in a vehicle development process. These methods were pione....
