In this paper, co-simulation procedure for a multibody system that includes reeving mechanism will be introduced. The multibody system under investigation is assumed to have a set of rigid bodies connected by flexible wire ropes using a set of sheaves and reels. In the co-simulation procedure, a wire rope is described using a combination of absolute position coordinates, relative transverse deformation coordinates and longitudinal material coordinates. Accordingly, each wire rope span is modeled using a single two-noded element by employing an Arbitrary Lagrangian-Eulerian approach.

The load transfer control equations under bolt-surrounding rock interaction are established on the basis of classical beam theory and the trilinear shear slip model. The axial stress and transverse shear force distributions of the anchorage body are obtained by solving the equations. The equivalent forces obtained by the transverse force and axial shear stress of the bolts are applied to rock mass elements to simulate the support effect. A new dynamic algorithm for bolts is proposed in considering of the axial and transverse deformation of the anchorage body. The rationality of the algorithm is verified by comparing with laboratory pullout and shear tests of bolts. A dynamic time-history case study of underground caverns is conducted using this algorithm. Results indicate that (1) the algorithm may reflect the stress and deformation characteristics of bolts during an earthquake; (2) for the antiseismic support effect of the surrounding rock at fault, the bolt algorithm in this study is more valid than the algorithm that considered only the axial deformation of bolts; (3) in the support force of the bolt to the surrounding rock, transverse force is the key to limit fault dislocation and reduce the dynamic damage of the rock at fault.

Thermo-mechanical controlled rolling (TMCR) schedules have been studied on the wire line of 400/200 section rolling mill to manufacture 6.0 – mm - diameter reinforcing wire in coils by V-alloyed C – Mn – Si - steel that has dual-phase (DP - ferrite-martensite (bainite)) and multi-phase (MP - ferrite-martensite (bainite) - pearlite) microstructures.It has been established that high tensile strength and plasticity values were achieved in this 6.0 – mm wire in coils (YS0.2= 530-550 MPa; TS= 785 – 885 MPa; El5  = 15.0 – 29.0 %) which were in full compliance with national standard specifications such as ASТM A 615 (USA), JIS G 3112 (Japan) and KSD 3504 (the Republic of Korea)), when the TMCR schedules involving laying head temperatures ТLH from 1024 ºС to 1063 ºС were employed ensuring formation of MP microstructure.

Contact Pressures

Based on application the physical constraint equations of state of stress and strain of the metal for the isotropic medium, we get expressions for components of stress tensor. The new theoretical method for calculation of contact pressures and rolling force during rolling of double-T section in a universal beam groove was developed. Reliability of the method is confirmed by the results of experimental verification for conditions of rolling of H-beam No 35B1, 40K2 and 45B2 from steel 15CrSiNiCu on the universal beam mill of "NTMK". The average calculation error is 6.4%. The new method is recommended for calculation pass design and technological modes of H-beam rolling on rail-beam and section mills, equipped with universal stands.
