Analysis about Static Characteristics of Machine Tool Bolted Joint Based on Virtual Medium

Abstract

The Department of Heavy NC machine tool is a complex structure. The working performance of the machine has the very big impact. The machine tool of influence is very important. In this paper the bolt combined with sub structure of Heavy NC machine tool as the research object, the. In conjunction with the Ministry of the virtual medium dynamics model method to establish the combination of fixed bolt. In this paper the bolt joint of Heavy NC machine tool as the research object. Combination of bolts binding kinetics model is established by using the virtual medium method The parameters change the dynamics of model, the influence of bolt pretightening force, tool materials and processing, has been part of the characteristics and rule of machine tool joint.
