intermediate shaft) will be explored as well as the role of the upper steering in the occupant protection system, steering non-uni- formity, and how torque and angle at the pinion is converted to torque and angle at the steering wheel.. Day Two will be devoted to the power assist system anatomy/ architecture for hydraulic, electro-hydraulic and electric power steering. Day Three will begin with a discussion of common steering objective tests and how system design and tuning affect steering response, torque feedback and error state performance. The seminar will conclude with a discussion of advanced steering systems such as rear wheel steer, active front steer, active park assist and other driver assistance systems. Students will have the opportunity to participate in exercises throughout the seminar with the objective of calculating a power steering assist curve for both a hydraulic and electric power steering system. Many physical parts will be available for the students to examine. This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 12 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should mail a copy of their course certificate and the $5 student CEU fee to ACTAR, PO Box 1493, North Platte, NE 69103. Learning Objectives By attending this seminar, you will be able to: • Identify common steering and suspension system architectures • Compare and contrast different types of steering gears • Describe the function of the steering column and intermediate shaft subsystem • Describe the influence of system tuning on steering response and torque feedback • Compare and contrast different types of power assist systems • Describe the effect of power steering on fuel economy • Calculate important parameters that affect steering response and torque feedback • Describe some of the features of advanced steering systems Who Should Attend This seminar is designed for automotive engineers in the vehicle dynamics, chassis, suspension, steering and chassis controls fields who work in product design, development, testing, simulation or research. Prerequisites Participants must have a working knowledge of the fundamentals of vehicle dynamics acquired through sufficient work experience or by participating in seminars such as SAE’s Vehicle Dynamics for Passenger Cars and Light Trucks (ID# 99020), Chassis and Suspension Component Design for Passenger Cars and Light
specification and maintenance, driver-trainers, and truck accident investigators will also find this course of value.

Fundamentals of Steering Systems 3 Days | Classroom Seminar I.D.# C0716
Design and development of a modern steering system influences vehicle response to steering wheel input, driver effort, comfort, safety and fuel economy. In this interactive seminar participants will analyze the steering system from the road wheel to the steering wheel. Day One will begin with a deep dive into the anatomy and architecture of the lower steering system (wheel end, suspension geometry, linkages and steering gear), its effect on vehicle response and how forces and moments at the contact patch are converted to a torque at the pinion. Next, the anatomy and architecture of the upper steering system (steering column and
