An Overview of Methods for Modelling Bolts in ANSYS
WebOct 2, 2024 · •Insufficient bolt preload may cause the bolts to become loose, leading to failure of the machine assembly or separation and lateral movement of the mating parts. •Since tightening of bolts produces tensile loads in the bolt, the bolt preload is also known as bolt pretension. 2 WebDec 1, 2024 · Ansys Mechanical provides a simple tool for applying a pre-tension load. If you have a model that contains a full bolt assembly representation, then you can simply select the cylinder surface (or half surface) that represents the bolt shaft and attach a bolt pretension load. shoal creek rehabilitation
