Wear Characteristics Analysis of Pin-on-Disc Pairs Based on Finite Element Model

The stress field distribution and change law of the friction surface are analysed in order to get the mechanism and characteristics of the wear pairs. The theoretical stress model of pin-on-disc pairs are observed according to the model of elastic half-space and the finite element model of it is built using the software of ABAQUS. The boundary condition and load are set and the stress change of the stationary state ,running-in period and stable situation are analysed respectively. The Mises stress ,contact stress and friction in different period are described and compared according to the simulated result of the finite element model.The experiment result shows the same characteristics of the simulation, so the advise is given to improve the frictional performance of the pin-disc pairs.

Hydrocarbon Migration Mechanisms of Hailar - Tamsag Basin

Based on the discourse of Hailar - Tamsag Basin description of hydrocarbon accumulation period and the distribution of hydrocarbon accumulation controlling factors, the paper pointed out Hailar - Tamsag basin specific landforms, which has significance to the study of ocean basins hydrocarbon migration mechanisms.

Study on the GFRP Tube Columns by Eccentricity and Concrete Strength Affection

For the study of eccentrically loaded GFRP tube columns filled with reinforced concrete, simulations were made with 21 specimens to study their load-displacement curves, treat concrete strength and eccentric load as main parameters.

Clastic Rock Physical Characteristics of Southern Songliao Basin Shiwu Fault Depression Layer

We sum up the reservoir space types and characteristics of clastic rock reservoir ShiWu fault depression rift layer study area, through core observation, microscope, scanning electron microscope and mercury injection methods, and discuss the development characteristics and formation mechanism of pore and fracture. A large number of core analysis, drill results and test mining research has confirmed that the study area is constructed by the strong force, the micro-cracks are well developed, it is not only important reservoir space, but also the flow of oil and gas wells to obtain high yield important seepage paths, is to obtain yield the necessary conditions.

Clastic Rock Reservoir Physical Characteristics of Southern Songliao Basin Changling Fault Depression Layer

We study the Changling fault depression layer reservoir space type and characteristic of clastic rock reservoirs in the study area, by core observation, thin section analysis, cathodoluminescence analysis, scanning electron microscopy and mercury intrusion method, and discusses the development of secondary porosity and fracture characteristics and formation mechanism.

Seismic Response Analysis of the Tank by Base Isolation

The storage tank plays a more and more important role in economic construction and the development. It always stores inflammable, explosive medium. The consequences are very serious, when the earthquake disaster occurs. In this paper, we build models of model tank and 20,000 m3 tanks with the finite element method, and analyze their seismic response between the former structure and the isolatied structure. We wish that the research can provide fundamental data for the similar studies.

Analysis of the Reinforced Masonry on Shear Capacity

The reinforced masonry structure system is turned up as a new group of high-rise building structure type. This paper mainly researched the shear of reinforced masonry structure under earthquake. The maximum shears of the structure are calculated in X and Y direction by numerical analysis method. The changing of the shear bearing capacity is presented under three kinds of seismic waves.

Comparative Analysis of the Reinforced Masonry Structure Bearing Capacity with Different Methods

At present, the reinforced masonry structure has been widely concerned. The development of the reinforced masonry structure with a good seismic performance and simple construction is very important. This paper mainly studies on the bearing capacity of the ten storey reinforced masonry structure under the action of earthquakes with three different methods, and given the corresponding data.

Study on the FRP Tendons in Acid Erosion Test of the Durability

Abstract：In this paper,HCI solution in the chemical corrosion tests carried out in room temperature,measured mass loss of CFRP tendons. After extraction and analysis, preliminary search the FRP reinforcement corrosion mechanism under acid erosion. The tensile test is done at 60d and 120d,respectively. Determination of the tensile strength of CFRP tendons. The experimental analysis of the data collected, identify the law of CFRP reinforcement corrosion. Fiber reinforced composite material (Fiber Reinforced Polymer, of FRP ) is a continuous non-metallic fibers and fabric reinforced thermosetting or thermoplastic resin matrix composite made of a new material . Fibers and resin matrix composed of FRP bars under normal circumstances is not easy to rust, but in recent years, the study found that acid salt , moisture , UV , temperature and other environmental conditions on the long-term performance of FRP bars have a certain impact[3-5]. By CFRP tendons under acidic corrosion durability test study reveals CFRP tendons under the corrosive effect of the variation of the quality and strength . Can provide a theoretical basis for CFRP tendons durability design , to provide theoretical guidance to improve the efficiency of the FRP bars in harsh conditions .

Research on The Internal Force and The Normal Displacement of The Storage Tank under Earthquake Action

Vertical storage tank is widely used as a liquid storage container in the oil deposit, petrochemical industry and related enterprise. It always stores inflammable, explosive medium. The consequences are very serious, when the earthquake disaster occurs. In this paper, we build models of model tank and 30,000 m3 tanks with the finite element method, and analyze their vibration characteristics and seismic response. We wish that the research can provide fundamental data for the similar studies.
