Research on Parameterized Modeling Technology for the Bolted Joints Structure

Abstract

Bolted joints structures exist in modern mechanical system, it is difficult to simulate the characteristics of the bolted joints accurately and effectively because of their complexity and diversity, which bring a great challenge to the whole structure modeling. Based on theoretical derivation of the bolted joints mechanical characteristics, the parameterized simulation technology and modeling method was used to equivalent simulate the bolted joints and with the example of a certain type of modern turbofan engine to elaborate the application of the parameterized modeling method. The research results have shown that the parameterized modeling method can not only simulate the true characteristics of bolted joints but also can improve calculation efficiency and saving computing cost effectively.
