Course content
When mechanical structures break down or faile, the fracture often occurs at bolted joints, rivets and welded portions. In this lecture, we pick up the bolted joints technology that you should know as the basis of the machine, and explain the strength of the bolted joints based on knowledge of material mechanics, material strengths, and design engineering. Students can learn how to design bolted joints and how to design fatigue.
Purpose of class
The purpose of this lecture is to learn about the basic mechanism of bolted joints in order to design with fatigue and loosening of bolted joints taken into consideration. For this purpose, students learn the importance of appropriate clamp force of bolted joints, and become to be able to calculate the tightening torque.
Goals and objectives
  1. To understand the strength system of bolted joints and to calculate the strength of bolts from the property class.
  2. To understand the mechanics of bouted joints and to explain the tightening method.
  3. To calculate fatigue strength of one member.
  4. To design some parts and bolted joints taling into account fatigue.
  5. To explain several joining techniques.
