AS13003 Measurement System Analysis (MSA) Requirements for Aerospace Engine Supplier Quality

2021-06-30
AS 13003:2015 stipulates requirements to establish an acceptable measurement system (for variable and attribute features) for use on aerospace engines parts and assemblies. Measurement Systems Analysis (MSA) is used to evaluate and improve measurement systems in the workplace because it evaluates the test method, measuring instruments, and the process of acquiring measurements. The Aerospace Engine Supplier Quality (AESQ) Strategy Group published AS13003 to define the minimum requirements for conducting MSA for variable attribute assessment on characteristics as defined on the drawing specification.

Model-Based Systems Engineering (MBSE)

2021-06-08
As the complexity of products increases, traditional text-based systems engineering can no longer meet the needs. To solve the problem, Model-based Systems Engineering offers a unified communication platform among relevant staff by carrying out diagram-based unambiguous description, analysis and design for the demand, structure and behavior of complex systems in the form of a model. It, however, still remains a challenge to implement MBSE modeling and model-driven technology and application as well as its integration with the industry.

Design of a Cover Plate Cum Powerpack Loading Platform for Armoured Engineering Vehicles

2020-09-25
2020-28-0356
Armoured engineering vehicles are a class of vehicles that cater to the engineering needs such as repair, recovery, technical maintenance, clearing obstacles etc. in field conditions for Main Battle Tanks (MBTs) during times of combat. In addition to the above needs, such vehicles are also supposed to carry sufficient spares including a spare powerpack that includes an engine cum transmission for MBTs as a piggyback during field replacement. Such requirements entail challenges in the design as locating such a powerpack on the vehicle impose additional structural strengthening and stability concerns during both static and dynamic conditions without obviating the need to carry vehicle spares and weight constraints. This paper tries to address these design challenges through a case study, wherein a cover plate that is supposed to seal the powerpack compartment from dust and water ingress is converted to a cover plate cum loading platform.

Reliability, Maintainability, and Sustainability Terms and Definitions

2020-04-21
CURRENT
J3119_202004
A glossary of basic terms and definitions useful for working in reliability, maintainability, and sustainability (RMS). The terms used in most engineering technologies tend to be physical characteristics such as speed, rate of turn, and fuel consumption. While they may require very careful definition and control of the way in which they are measured, the terms themselves are not subject to different interpretations. Reliability, maintainability, and sustainability (RMS), however, use terms that are defined in a variety of ways with multiple interpretations. The variety of definitions given to a single term creates problems when trying to compare the performance of one system to another. To eliminate the confusion, a literature search that listed current and past RMS terms and definitions was conducted. The literature search included input from the U.S. military, UK military, NATO, SAE, IEEE, NASA, ISO, university research, and other publications.

Unsettled Technology Opportunities for Vehicle Health Management and the Role for Health-Ready Components

2020-03-17
EPR2020003
Game-changing opportunities abound for the application of vehicle health management (VHM) across multiple transportation-related sectors, but key unresolved issues continue to impede progress. VHM technology is based upon the broader field of advanced analytics. Much of traditional analytics efforts to date have been largely descriptive in nature and offer somewhat limited value for large-scale enterprises. Analytics technology becomes increasingly valuable when it offers predictive results or, even better, prescriptive results, which can be used to identify specific courses of action. It is this focus on action which takes analytics to a higher level of impact, and which imbues it with the potential to materially impact the success of the enterprise. Artificial intelligence (AI), specifically machine learning technology, shows future promise in the VHM space, but it is not currently adequate by itself for high-accuracy analytics.

FEA Beyond Basics: Nonlinear Analysis Web Seminar RePlay

Anytime
Finite Element Analysis (FEA) has been an indispensable tool for design simulation for several decades but this wide spread use has been limited to simple types of analyses. Relatively recently, more advanced analyses have given easy-to-use interfaces enabling design engineers to simulate problems formerly reserved for analysts. FEA Beyond Basics targets the FEA users who wish to explore those advanced analysis capabilities. It will demonstrate how to move past the ubiquitous linear structural analysis and solve structural nonlinear problems characterized by nonlinear material, large displacements, buckling or nonlinear connectors.

Fundamentals of Fatigue Analysis

Fatigue is a structural failure mode that must be recognized and understood to develop products that meet life cycle durability requirements. In the age of lightweighting, fatigue strength is an important vehicle design requirement as engineers struggle to meet stringent weight constraints without adversely impacting durability. This technical concept course introduces the fatigue failure mode and analysis methods. It explains the physics of material fatigue, including damage accumulation that may progress to product failure over time, and it provides the needed foundation to develop effective fatigue prediction capabilities.

2019-28-0124
Currently, for various military activities such as construction of bridges, digging trenches, construction of roads and clearing the area during landslides, separate unit of bulldozer for dozing operation and loader for loading operation is required. But the need is to develop a single unit which could perform both of these operations efficiently and simultaneously. The paper discusses about the development of dozer bucket mechanism as a single unit to perform dozing and loading operation and connected to the amphibious infantry combat vehicle. To develop the dozer bucket mechanism synthesis of mechanism (Linkages and Boom) has carried out and care has taken to fulfill the above stated functional requirement and satisfy the geometrical constraints. The synthesis of mechanism is done with the help of ‘CATIA’ software packages. The force calculation on various joints at the different position of mechanism has evaluated with the help of ’ADAMS’ software.

Building Multiple Resolution Modeling Systems Using the High-Level Architecture

2019-09-16
2019-01-1917
The modeling and simulation pyramid in defense states it clearly: Multi-Level modeling and simulation are required. Models and simulations are often classified by the US Department of Defense into four levels—campaign, mission, engagement, and engineering. Campaign simulation models are applied for evaluation; mission-level simulations to experiment with the integration of several macro agents; engagement simulations in engineered systems development; and engineering-level simulation models with a solid foundation in structural physics and components. Models operating at one level must be able to interact with models at another level. Therefore, the cure (“silver bullet”) is very clear: a comprehensive framework for Multiple Resolution Modeling (MRM) is needed. In this paper, we discuss our research about how to construct MRM environments.
