I.D.# C0948

Printable Description

Duration: 1 Day

August 2, 2013 (8:30 a.m. - 4:30 p.m. ) - Troy, Michigan

Hotel & Travel Information

Ride comfort engineering is an essential element in the design of heavy vehicles and has a direct impact on operator performance, market differentiation, and overall customer satisfaction. Practitioners in the commercial vehicle industry must be able to assess the effects of noise and vibration on operator comfort and performance. This one-day seminar provides a comprehensive evaluation of heavy vehicle ride comfort engineering, balancing fundamental concepts with contemporary issues.

This seminar begins with the fundamentals of ride comfort engineering, covering the elements that impact operator comfort and fatigue in heavy vehicles, particularly heavy trucks. This will include vehicle components that influence vibrations being transmitted to the operator such as cab and seat suspensions, cab layout, and sleeper arrangement. Additionally, this seminar includes an evaluation of the impact vibrations have on the human body and motor skills as they pertain to vehicle operation. This seminar concludes with two case studies that highlight some of the new technologies that can assist the attendee in evaluating and improving truck ride dynamics.

Please note: Individuals that have attended the Fundamentals of Heavy Truck Dynamics seminar should be aware there is considerable overlap in the content presented in this seminar.

Learning Objectives
By attending this seminar, you will be able to:

• Describe heavy vehicle ride engineering and the factors that influence it, both in theory and in practice
• Identify the vehicle components effecting vibrations in heavy vehicles
• Evaluate cab and seat suspension dynamics
• Identify the impact vibrations have on human comfort and fatigue
• Predict how various sub-systems interact with each other to influence truck dynamics
• Evaluate some of the contemporary issues in heavy truck dynamics

Who Should Attend
This seminar will benefit design, manufacturing, and customer support engineers in the heavy truck industry, most notably the original equipment manufacturers and their suppliers. Managers and marketing staff, as well as individuals in government agencies and educators in academic institutions that have a need for understanding heavy vehicle ride dynamics will also benefit from attending this seminar.

Prerequisites
A basic knowledge of college-level statics, dynamics, and vibrations will help the attendees to more easily follow the course material. Practical knowledge and common sense can replace the academic training in statics and dynamics.
