Dynamics of Joints

1-Day Practical Workshop on Wednesday, 29th March

Structures are built-up from components connected by joints. For a structure with a vibration duty there are many uncertainties:

  • Can static joint design be used for dynamic design?
  • What is the dynamic stiffness of a joint?
  • How much damping is provided by a joint?
  • How do you model the dynamics of joints in simulation codes?
  • Can joints be designed to assist structural dynamic?
  • How repeatable and predictable is the behaviour of a joint?
  • Can joints be simplified to reduce weight and complexity?

Research into these issues has received growing attention and some answers are now available. This workshop introduced the problems, the current knowledge, some approaches and some solutions. Helping to reduce modelling uncertainty by gaining the current knowledge. 

In the morning there were talks from leading experts who described the current state of knowledge and provided the needed background knowledge.     

Practical Session

In the afternoon delegates were able to experiment with various joints. They applied dynamic loads to see how an instrumented joint responded. Delegates were able to assemble and disassemble joints and examined the dynamic behaviour.
