Abstract :
The structural design and analysis of the BPX central solenoid are presented. The large-scale structural behavior of the solenoid is simulated with a 2D axisymmetric ANSYS finite element model. The computer model is used to determine the time-dependent stress history in the coils and tie rods, and to perform various structural performance studies. Some of these studies are included, such as tie-rod preload optimization, relative movement at low-friction surfaces and alternate material and transient cooldown effects. The results of these simulations are presented and discussed. A fatigue analysis of the conductor stresses is presented based on the BPX design criteria and preliminary material property data. The relationships between the 2D solenoid model and more detailed 3D models of subcomponents are also discussed
