Most muffler design in the automotive industry is accomplished by using "cut-and-try" methods that rely on what has worked in the past and/or extensive full-scale testing on engines for validation. New computer software aimed at muffler design can shorten the design cycle and yield more effective results. This four hour seminar provides an introduction to the behavior of mufflers and silencers including a description of the two-port approach to muffler design. This seminar covers the acoustic simulation of muffler and silencer systems and the use of experimental methods to measure muffler performance.

Workflow knowledge comprises both explicit, verbalizable knowledge and implicit knowledge, which is acquired through practice. Learning a complex workflow therefore benefits from training with a permanent corrective. Augmented Reality manuals that display instructive step-by-step information directly into the user's field of view provide an intuitive and provably effective learning environment.

Standard paper or electronic forms of work instructions have been used to standardize manual processes since the first days of manufacturing, and are still in wide use today in factories around the world. As augmented reality (AR) technology has continued to advance at a rapid pace, it is opening new doors to drive higher levels of quality, productivity, and training efficiency into worldwide manufacturing processes through its unique ability to place the right information, at the right place, and at the right time.

Discuss and demonstrate the advances in Man Wearable AR/VR systems that have been under development at Lockheed Martin. The trials and successes of designing, prototyping and manufacturing plastic Asymmetric lens for AR displays that provide Wide Field of views using COTS displays. The second display takes advantage of a specially designed Fresnel lens set to create a 170 degree VR display. These display systems designs are focused on Military Training requirements but should not be limited in their use.

During development phase of new vehicles prototypes are traditionally assembled manually by operators. Two of the main challenges for workers are to position flexible parts (such as brake tubes, cables and wiring) at exactly the right position and to verify if all parts are present during the assembly. To complete this process, operators are currently using drawings to compare the real prototype with the virtual CAD Data. One issue is that no measurement tools can verify exactly the position of flexible parts within a reasonable time frame. Augmented Reality solutions stand to both accelerate detection of construction and design errors while helping operators to place components or flexible parts at the exact position required. By overlaying the virtual CAD 3-D model on the real prototype with a high accuracy, operators are able to quickly compare the potential points of failure and detect if any components are missing. Furthermore the system allows designers to preview or evaluate design alternatives in real scale while minimizing the production of physical prototypes.

Augmented Reality (AR) enriches the user’s view by superimposing available digital information in context with the real world in the right place at the right time. These systems usually consist of four different elements: tracking, real images, virtual content and visualization. Tracking is the centerpiece of our technology. The perspective and coordinates of a camera - the so-called “pose” -are determined optically, with external or internal sensors. Depending on the use case, a wide range of virtual content is applicable, from simple text or symbols to 3D models that originate from a CAD system. Visualization means that the actual scene and virtual content are aligned correctly regarding perspective, scale and position, while being displayed for the user. The workshop will focus on the creation of an Augmented Reality scene and will be demonstrated through a live demo, which shows how to create your own AR scenarios. It will also explain the different tracking possibilities and how to choose the most appropriate one.

Augmented reality has tremendous value in many aspects of life. Applications in a traditional manufacturing facility bring with it opportunities but also unique challenges. We will explore the value which AR can expose and open up to improve productivity and cost controls. The presentation will show how AR technologies can be used for work cell planning and layout, dynamic work instruction presentation to operators, and mistake proofing assistance.

Virtual Reality systems are quickly hitting the consumer market at a significantly reduced price point. This will have an impact across many industries, including the mobility market. More than just a reduced cost implication, we will examine the benefits the newly accessible technology will have on everyday operations where usage will be at the desk and in the field versus the lab, product design where lower-cost technology does not compromise quality, and hands-on employee training that can be conducted in boundaryless classrooms.

The presentation will hopefully cover research that JLR are doing with the UK universities to progress the virtual experience, thus enhancing the virtual sign off process. It will cover how this research is bolstering current effective virtual work practices, it will touch on the benefits and justification we use to develop and invest, whist also highlighting the passion of virtual reality.

In this study, numerical simulations of in-cylinder processes associated to fuel post-injection in a diesel engine operated at Low Temperature Combustion (LTC) have been performed. An extended Conditional Moment Closure (CMC) model capable of accounting for an arbitrary number of subsequent injections has been employed: instead of a three-feed system, the problem has been described as a sequential two-feed system, with the conditioning scalar being the total mixture fraction. A reduced n-heptane chemical mechanism coupled with a two-equation soot model is employed. Numerical results have been validated with measurements from the optically accessible heavy-duty diesel engine installed at Sandia National Laboratories, comparing apparent heat release rate (AHRR), in-cylinder soot mass evolution and exhaust filter smoke number (FSN) for a wide range of post injection dwell times. Subsequently, numerical investigations on the effects of different post injection timings on soot formation and oxidation processes is presented, with particular emphasis on the role of the increased mixing by post injections.
