deformation chain
1.The arbitrary motion of a viscoelastic fiber modeled by a 3-bead-2-rod link suspendedin a homogeneous flow field whose velocity is linear in the Cartesian coordinates is developedby means of resolving the motion and deformation of the chain model into itsquasi-rigid-chain motion and pure deformation components.
2.Base on the elasticity contact and deformation theory, study the contact load and deformation of the pin and the link chain.
3.Exceed the load-carrying resistance and wear resistance for top layer of pin and bush, resistance to plastic deformation for centre of pin and bush, circular softness and hardening characteristics for top layer, they are key factors for the tribology design of the high-speed automotive chain.
4.For a finite chain, the Bethe Ansatz equations(BAE) are very complicated. In terms of q-deformation Young operators this Hamiltonean system can be reduced to a set of coupled linear algebraic equations, which could be explicitely solved.
5.Link chain products of the C grade made of domestic 23MnNiCrMo54 steel were often accompanied with the uneven pretensile deformation and low fatigue life. For this reason,the microstructure of rolling bar from the domestic and imported steels was analyzed and compared with SEM. The results shows that the uneven microstructure exists in the domestic steel remarkably,which will effect on the distribution of carbide after quenching and tempering.
