| Abstract: | Based on the large finite element analysis software,i.e.ANSYSTM,and the nonlinear contact analysis,the pretightening dynamical properties of two plastic thread connections are studied.From the analysis results,it is found,that the stress of improved thread connection,which is recommended for applications,is significantly reduced with even distribution. |
