Free Multibody Cosimulation Based Prototyping of Motorcycle Rider Assistance Systems

2020-11-30
2020-32-2306
Due to the increasing computational power, significant progress has been made over the past decades when it comes to CAD, multibody and simulation software. The application of this software allows to develop products from scratch, or to investigate the static and dynamic behavior of multibody models with remarkable precision. In order to keep the development costs low for highly sophisticated products, more precisely motorcycle rider assistance systems, it is necessary to focus extensively on the virtual prototyping using different software tools. In general, the interconnection of different tools is rather difficult, especially when considering the coupling of a detailed multibody model with a simulation software like MATLAB Simulink. The aim of this paper is to demonstrate the performance of a motorcycle rider assistance algorithm using a cosimulation approach between the free multibody software called FreeDyn and Simulink based on a sophisticated multibody motorcycle model.

CALS Configuration Management SOW and CDRL Guidance

2020-10-20
WIP
CMB7_3A
the purpose of the Statement of Work is to define the Configuration Management requirements necessary to maintain and control CALS databases and provide transmission, access and receipt of digital data between contractors, subcontractors, vendors and the government. Digital data includes not only traditional configuration management documents such as specifications, drawings, and ECP's but includes all technical data listed in the CDRL. This Model SOW document will provide the government suggested SOW wording that should be included in RFP's and guidance in applying those SOW paragraphs.

Unsettled Topics Concerning Adopting Blockchain Technology in Aerospace

2020-10-19
EPR2020021
Aerospace is an industry where competition is high and the need to ensure safety and security while managing costs is foremost. Stakeholders, who gain the most by working together, do not necessarily trust each other. Changing backbone technologies that drive enterprise systems and secure historical records does not happen quickly (if at all). At best, businesses adapt incrementally, building customized applications on top of legacy systems. The complexity of these legacy systems leads to duplication of efforts and data storage, making them very inefficient. Technology that augments, rather than replaces, is needed to transform these complex systems into efficient, digital processes. Blockchain technology offers collaborative opportunities for solving some of the data problems that have long challenged the aerospace industry.

CURRENT
AS6969A_DA
Enhanced License and UML Model for Data Dictionary for Quantities Used in Cyber Physical Systems (AS6969) allowing for greater usage as outlined in the terms of the Enhanced License. Data Dictionary for Quantities Used in Cyber Physical Systems (AS6969A) This data dictionary provides definitions for quantities commonly used in the command and control of cyber physical systems. It defines mathematical and logical terms, quantities, measurement units, reference systems, measurands, and measurements. It also defines common quantity modalities. The dictionary is structured to be convenient to data modelers. It is also extendable so that users can create their own quantity domains.

This data dictionary provides definitions for quantities, measurement units, reference systems, measurands, measurements and quantity modalities commonly used in the command and control of cyber physical systems. A cyber physical system is an engineered system that is built from, and depends upon, the seamless integration of computational algorithms and physical components. Cyber physical systems are often interconnected via data links and networks. The term encompasses intelligent vehicles and devices that operate in any environment, including robotic and autonomous systems.

CURRENT
J3067_202010
This document is not a standard, it is a candidate for a standard being submitted to SAE for their consideration as a comment to SAE J2735. The term SAE J2735 SE candidate is used within this document to refer to this submission. This document specifies dialogs, messages, and the data frames and data elements that make up the messages specifically for use by applications intended to utilize the 5.9 GHz Dedicated Short Range Communications for Wireless Access in Vehicular Environments (DSRC/WAVE, referenced in this document simply as “DSRC"), communications systems. Although the scope of this Standard is focused on DSRC, these dialogs, messages, data frames and data elements have been designed, to the extent possible, to be of use for applications that may be deployed in conjunction with other wireless communications technologies.
