A Dictionary of Terms for the Dynamics and Handling of Single Track Vehicles (Motorcycles, Scooters, Mopeds, and Bicycles)

Motorcycle Technical Steering Committee
  • Ground Vehicle Standard
  • J1451_201909
  • Current
Published 2019-09-24 by SAE International in United States
This dictionary of terms was prepared for use by those with a need to describe and understand the dynamics and handling of two-wheeled, single track vehicles. It is intended to span the gap between vehicle dynamics specialists and those with a more general interest. This report is pertinent to such areas as vehicle design and development, the description of two-wheeler properties, rider training and education, and the preparation of standards and regulations. This report was prepared by the SAE Motorcycle Committee, which solicits suggestions for improvements and additions to be considered in future revisions. Comments should be directed to SAE Headquarters.

Motorcycle Terminology

Motorcycle Technical Steering Committee
  • Ground Vehicle Standard
  • J3133_201909
  • Current
Published 2019-09-24 by SAE International in United States

The motorcycle terminology presented herein addresses two-wheel single track vehicles, as well as motorized three wheel cycles. Although two-wheeled, single track scooters and mopeds are similar to traditional motorcycles, they have many characteristics which differentiate them from motorcycles, and while some terms will apply, this Terminology addresses motorcycles specifically, unless otherwise noted. Likewise, some three wheel cycles may have some similar design features and share components with motorcycle, the dynamics and handling of three wheel vehicles differs from two wheel, single track motorcycles.

Step & Repeat: Reduce Derivative Aircraft Development Risk with Design Reuse

Mentor-Muhammad Askar
Published 2019-09-16 by SAE International in United States
The complex and risky process of designing derivative aircraft, especially when it comes to electrical systems, can be a daunting task at best. There are a number of design strategies that can be employed to mitigate risk and increase the overall efficiency. Quite simply, the current methods of manual processes, design and integration approaches that were optimized from mechanical approaches, are no match for today’s complexities.One method gaining significant traction is to employ a central database serving global interface definitions for the entire design process. Automation through generative design minimizes manual intervention and repetitive work. Furthermore, detecting changes through design rule checks allows system engineers to verify their designs, capturing both inadvertent and planned changes. The ability to instantly update the design content from the new definition streamlines the change management process.Employing these technologies in a digital, connected thread, ensures that intelligent information is leveraged at every step along the way from aircraft conception, realization, and finally to utilization - thereby minimizing risk and maximizing efficiency.

Brake Pedal Feeling Comfort Analysis for Trucks with Pneumatic Brake System

Ford Motor Company-Wesley Bolognesi Prado, Silvia Faria Iombriller, Marco Andre Silva, Lázaro Renato Oliveira
Published 2019-09-15 by SAE International in United States
The brake pedal is the brake system component that the driver fundamentally has contact and through its action wait the response of the whole system. Each OEM defines during vehicle conceptualization the behavior of brake pedal that characterizes the pedal feel that in general reflects not only the characteristic from that vehicle but also from the entire brand.Technically, the term known as Pedal Feel means the relation between the force applied on the pedal, the pedal travel and the deceleration achieved by the vehicle. Such relation curves are also analyzed in conjunction with objective analysis sheets where the vehicle brake behavior is analyzed in test track considering different deceleration conditions, force and pedal travel.On technical literature, it is possible to find some data and studies considering the hydraulic brakes behavior. However, for pneumatic brake systems, the pedal feel theoretical study is not usual, where is normally used for these developments, exclusively the subjective evaluation which become necessary to have more specialists to define the brake pedal behavior.Throughout this article will be revised the characteristics concepts…

Perceptive Automata partners with Volvo Trucks to demonstrate AI technology that can determine when pedestrians will cross the road.

The automotive and commercial vehicle industries are working on answers to a tremendous number of questions no one bothered to ask before. Volvo, for example, wants to know if vehicles can have human intuition.
