AS91002016 Rev D Understanding the Requirements

2021-06-17
Individuals responsible for quality management system, implementation, and auditing to the AS9100:2016 series of standards for Aviation, Space, and Defense will require an understanding of the requirements for the preparation and execution of the audit process as defined in these revised standards. Management and implementers of AS9100:2016 Rev. D within these organizations must also be aware of what these requirements mean for their company.

Theories and Methods of Future HMI Design for Automobiles

2020-11-12
HMI design is an Interdisciplinary, which is based on human cognitive psychology and combines humanities, sociology, aesthetics, information science and other disciplines. While automotive technologies can be applied regardless of regions, HMI must be localized, as it is closely related to regional culture, people's living habits and characteristics. At the same time, HMI design has its own complete theoretical system, research and design methods and testing methods, instead of relying on experience. The purpose of this course is to equip people involved in the automotive industry with a basic sense of HMI design of vehicles.

Design and Evaluation of Automotive Static Perceptual Quality

2020-11-06
Static perceptual quality is the term applied to the customer’s first impression of a car at the beginning of the buying process including how it looks, feels, and smells. This “first feeling” largely determines whether the customer continues through the purchase process. At present, OEMs have no systematic method for static perceptual quality in the whole vehicle design and development process, especially for the static perceptual quality review in the early stage of design and development before data freezing. Usually, it can only be evaluated after the vehicle is produced and assembled.

Wall Heat Flux on Impinging Diesel Spray Flame: Effect of Hole Size and Rail Pressure under Similar Injection Rate Condition

2020-10-30
2020-32-2313
The fuel economy of recent small size DI diesel engines has become more and more efficient. However, heat loss is still one of the major factors contributing to a substantial amount of energy loss in engines. In order to a full understanding of the heat loss mechanism from combustion gas to cylinder wall, the effect of hole size and rail pressure under similar injection rate conditions on transient heat flux to the wall were investigated. Using a constant volume vessel with a fixed impingement wall, the study measured the surface heat flux of the wall at the locations of spray flame impingement using three thin-film thermocouple heat-flux sensors. The results showed that the characteristic of local heat flux and soot distribution was almost similar by controlling similar injection rate except for the small nozzle hole size with increasing injection pressure.
