煤矿机械用Q690高强钢抗裂性研究

对煤矿机械用Q690高强钢,采用其配套焊丝(GHS75M)进行抗裂性试验,并测定了焊丝熔敷金属扩散氢逸出特性,研究了焊缝金属残余扩散氢对试验用钢抗裂性的影响.结果表明:该钢具有一定的冷裂倾向.试验焊材熔敷金属扩散氢含量为1.7 mL/100 g,初期扩散氢逸出速率较大,在焊缝冷却过程中扩散氢可以较快逸出.残余扩散氢含量主要与从峰值温度到100℃温度区间的冷却时间t100有关,单道焊焊缝金属冷速快,t100较小,残余扩散氢较多,而多层多道焊增加了t100,且提高HDr100容许值,残余扩散氢含量很低.该钢采用焊后热处理是保守的工艺.

Influence of the instability of angular velocity of the rotating carrier itself on the stability of silicon micromachined gyroscope

In order to find out the influence of the instability of angular velocity of the rotating carrier itself on the stability of silicon micromachined gyroscope, the digital model for relative error of the high and low damping gyroscope’s output signal is given respectively, based on the motion equations of the silicon micromachined gyroscope. Theory proved that the output signal error of the silicon micromachined sensor is mainly caused by the instability of damping factor and the angular velocity of the rotating carrier itself. The result of experimentation indicates that the error of proportionality coefficient of output voltage which caused by the instability of the angular velocity of the rotating carrier itself reaches to 4.1 per cent. Theoretical demonstration and experimental verification show that the instability of angular velocity of the rotating carrier itself has an important effect on the stability of low damping silicon micromachined gyroscope.

Management of the Quality of Corrosion Protection of Structural Steel Based on Corrosion Risk Level

The paper deals with the theoretical and practical aspects of improving regulatory and technical framework for assuring the quality and safety of metal structures and their protective coatings under the exposure of corrosive environment. Methodological approach has been developed to managing technological safety, assessing the risks of corrosion failures, and extension of an industrial facility＇s life based on company standards taking into account the requirements for safe operation of buildings and installations. Basic provisions of the method of limit states design have been analyzed to determine： design characteristics of corrosion impacts, computational models and design cases for affirming compliance of corrosion resistance, and durability and maintainability of structures and their protective coatings. Presented are practical examples of justifying the choice of means of primary and secondary protection, taking into account classification of the established levels of facility corrosion hazard. On the basis of limit state design principles, logistical control- and decision-making system is generated for reliability assurance of steel structures and protective coatings. Assessment criteria are specified for the risks with the use of the materials and technologies of primary and secondary corrosion protection.     

Application of dynamic analysis of strength reduction in the slope engineering under earthquake

At present, the methods of analyzing the stability of slope under earthquake are not accurate and reasonable because of some limitations. Based on the real dynamic tensile-shear failure mechanism of slope, the paper proposes dynamic analysis of strength reduction FEM and takes the reduction of shear strength parameters and tensile strength parameters into consideration. And it comprehensively takes the transfixion of the failure surface, the non-convergence of calculation and mutation of displacement as the criterion of dynamic instability and failure of the slope. The strength reduction factor under limit state is regarded as the dynamic safety factor of the slope under earthquake effect and its advantages are introduced. Finally, the method is applied in the seismic design of anchors supporting and anti-slide pile supporting of the slope. Calculation examples show that the application of dynamic analysis of strength reduction is feasible in the seismic design of slope engineering, which can consider dynamic interaction of supporting structure and rock-soil mass. Owing to its preciseness and great advantages, it is a new method in the seismic design of slope supporting.
