High strength stainless steel wire mesh-polymer mortar reinforcement method was a kind of advanced reinforcement technique.The present study attempted to do a model analysis on the test of the high strength steel wire mesh-polymer mortar reinforcement of less stress beams by using finite element software ANSYS. The study was conducted through the analysis of the three factors of the tested bending reinforcement beam’s deflection, deformation and stress and comparison of the changes of the beam’s ultimate load and failure mode before and after reinforcement.The results of ANSYS analysis and the test showed that the failure mode shifts from less reinforcement damaged into reinforcement destruction;the crack loading value of the reinforced beams increased indicating that the beam bottom reinforcement layer had a significant effect on the increase of the beam’s crack loading. Increased significantly compared to non-reinforced ultimate bearing capacity of reinforced beams. the ANSYS finite element simulation agrees well with the experimental value.

A steel reinforced plastic pipe (PSP), which is composed of two layers of high density polyethylene (HDPE) matrix and a high strength steel wire mesh skeleton, has wide applications in many industrial areas, such as gas and petroleum transportation, etc. In order to achieve higher efficency and lower costs, a large diameter PSP has been developed. However, requirements of the large diameter PSP in safety and economy are much higher, compared with those small diameter PSPs, and some potential problems should be taken into account. In this paper, relevant structural parameters of the large diameter PSP are determined, based on a previously proposed model, and a short-term burst test is carried out. The experiment results agree with the theoretical results quite well. Subsequently, the resistance of vertical pressure and uniform external pressure are evaluated by using experiment investigation and finite element method, respectively. And corresponding results indicate the large diameter PSP with determined structural parameters is qualified to use.

Before And After

Based on the computer simulation technique, this paper used the professional gear design software MASTA and finite element software ANSYS combined with the method of gear micro-modification to redesign the gear profile and eventually realized the optimization design of gear micro-modification. Then the gear transmission model of one-level reducer was established to simulate and analyze the contact equivalent stress, transmission error, and meshing impact before and after gear modification. By comparing the simulations results it is found that gear micro-modification can lower meshing impact load, reduce the vibration strength, make gear transmission steady, and improve the gear bearing capacity. By comparing the transmission error curves and meshing impact load curves before and after gear micro-modification, this helps to understand the effects of gear micro-modification on the gear transmission and provides basis references for the future redesign of the marine gears with high strength and long service life.

Reinforcing reinforced concrete (RC) beams with galvanized welded steel wire mesh is one of the latest technologies applied in retrofitting. For each sample, the experimental evaluation of 18 small reinforced concrete beam samples with a total length of 1200 mm was carried out to study the bending strength under static load conditions. Experimental testing has been carried out to the activated failure mode, with 11 reinforced samples, 4 integrally cast control beams and three original control beams. Based on the test variables, namely SWM characteristics and connection mechanism, the reinforced beams are divided into two groups A and B. This study also clarified the bending resistance, ductility, stiffness, crack width and deflection. According to the test results obtained, all reinforced beams are designed to fail ductilely. The first group of reinforced beams recovered to an average of 110% of the bearing capacity of the original control beam, while the second group of reinforced beams recovered to an average of 163%. Furthermore, it was found that the reinforcement beam functions in the same way as the general control beam and works as a unit. Therefore, the bottom line is that this reinforcement technology can be used confidently in real-life applications, especially in low- cost buildings.

Few Data

Damping materials made of pressing wire, such as Metal Rubber (MR material), “metal-flex”, “spring cushion” etc. are used widely in vibration protection systems. They have high strength and damping, however they are non-linear and anisotropic. To use contemporary finite element software for calculation of vibration insulators made of wire damping material one should know constants of this material. Till this time this problem almost isn’t researched, there is only a few data in linear approximation. A Young modulus for pressure and bending, shear modulus, Poisson ratio, friction force for pressure and for shear, friction coefficient between wire material and steel plate are obtained for MR material made of stainless steel wire for different load directions by static experiment in the present research. An influence of deformation, relative density, wire diameter, pressing force, deformation in other direction on these constants is considered. Peculiarities of pressing wire material deformation process are discussed: a difference of Young modulus for pressure and bending, a stabilization of hysteretic loop for one direction during load in another direction, an energy dissipation coefficient for different load directions. Results of the present research not only allow calculation of vibration isolator made of MR material by finite element software, but give a method for research of other pressing wire damping materials.
