Advanced Topics in Seat Suspension Design and Human Body Vibration Control
Duration: 2 Days
The objective of this two-day seminar is to provide the latest technology and research on testing and evaluation of ride comfort and proposed seat suspension design. Attendees will focus on how to evaluate and control human response to various types of vibration in different vehicles. Models of the seat and operator subjected to various types of input including impulses, multi-frequency sinusoidal types of vibration, and random excitation will be addressed as well as the examination of current seat suspension designs using passive, semi-active optimization and control strategies.
Learning Objectives
Upon completion of this seminar, attendees will be able to:
- Identify modeling techniques of seat/driver/passengers
- Review seat suspension optimization
- Discuss ride comfort quantification
- Describe sensor selection, data acquisition, calibration and filtering
- Compare active versus semi-active suspension
- Recognize how to further evaluate seat comfort dynamics that contribute to better seat design
Who Should Attend
This seminar will be especially beneficial to those involved in seat design and those evaluating seat ride dynamics and how vibration affects the human body.
Prerequisites
An engineering background in a related field and some knowledge of human body vibration is recommended.
