In the process of Finite Element Analysis (FEA) of mechanical structural system, the bolt pretension was often simulated in bolt fastening with components. Three methodology of Pretension Elements Method, Falling Temperature and Penetrative Contact Method as well were proposed and compared with each other using FEA technology in ANSYS. The simulation result was close to the theoretical value when using Pretension Elements Method, while was much bigger than the theoretical one when using the way of Falling Temperature as well as Penetrative Contact. It has been proved to be a very good way as well as reliable theory and application foundation for Pretension Elements Method in simulating real preloading in jointed bolt using Finite Element Analysis.
