Fundamentals of Spring Design

A practical problem-solving seminar created for those who design compression,
extension and torsion springs, and who select materials. This two-day program will
incorporate the use of the SMI spring design software.

Spring Design Basics
"In most cases, the primary objective of the spring designer is to design a spring which will do the job required and at the same time be the most economical, all things considered." - A.M. Wahl, Mechanical Springs

Wahl never had to deal with so many types of materials and cost considerations as designers face today.

With the pressure to meet deadlines plus superior quality considerations, today's spring designer faces problems that were virtually unknown just a few years ago.

This seminar will cover the basic problems faced by designers and offer solutions to help meet customers' needs.

The primary tool will be the computer and SMI's spring design software. It is not necessary to purchase the software to participate in the seminar. Effort is made to provide students with individual computers for the session, and practical applications will be developed during this intensive two-day seminar.

In addition to dimensional and load characteristics, intelligent spring design depends upon the considerations of many factors, such as stress, fatigue life, tensile strength and tolerances.

The selection of materials is another major step in the design of all types of springs. The seminar will consider the four major metallurgical classifications: carbon steels, alloy steels, stainless steels and non-ferrous spring materials. For proper design, factors such as temperature and corrosion, conductivity, physical properties, and available material types must be considered.

Who Should Attend
All those interested in acquiring a basic understanding of spring design, blueprints and SMI's spring design software. This group may include spring company inspectors and supervisors, and design engineers, as well as those in management, purchasing and quoting.

Requirements
Students should have basic math skills and a moderate understanding of how springs are manufactured. The SMI spring design software will be used in the seminar, but it is not necessary to own either a computer or this particular software. You may, however, purchase the software from SMI for use in your later daily work.

Confirmation
A confirmation will be sent to all participants 30 days before the start of the seminar. Attendees are responsible for their own travel and hotel accommodations, if necessary.

Cancellation Policy
SMI reserves the right to cancel the program 30 days prior to the session if an insufficient number of students apply for participation. It is recommended that participants not purchase airline tickets until 25 days before the program. In case of cancellation, SMI will refund all deposits but will not assume responsibility for airline costs.

The enrollment fee (less a $50 nonrefundable registration charge) will be refunded up to 14 days prior to the start of the program if an attendee must cancel for any reason. Personnel may be substituted up to the time of the seminar at no additional cost.
