Effects of flexible supports on explosion resistant capabilities of arches

Design of Die-cast Mould for Rotating Bracket and Its Die Casting Processing;

It is a general measurement to use the"typical equation"for either the force or the translocation when counting the statically indeterminable construction internal force in abutment remove,thus it makes the counting more common and regular.

Considering the reasons of the bending temperature stress and the characteristic distributed for it,in this paper,a measure is promoted by setting sliding support at the s.

This papes proposes one shock-resistant test for the construction with sliding support.

Meanwhile,various sliding bearings,swinging columns and steel shuttle-shaped truss columns are put into application to reduce the roof span and enrich the architectural image as well.

Some controlled sliding quantities of the connecting sliding bearing are calculated and suitable sliding bearing is designed.

Analysis on vibration characteristics of rotor system with pedestal looseness;

Chaotic behaviour of a rotor bearing system with pedestal looseness;

According to the specific features of a non-linear rolling element bearing-rotor system with pedestal looseness at one support, this paper derived its dynamical equations by using the theories of Hertz theory,nonlinear dynamics and rotor dynamics, which took into account the nonlinear condition of the looseness.
