In this investigation, the compression behavior of COx argillite with two different grain size distributions, which were obtained by two different crush procedures, was studied by running 1D compression tests with several loading-unloading cycles.
通过开展一维压缩试验,研究2种不同粉碎工艺下获得的粗/细COx土样的压缩特性,结果表明:压缩曲线受粒度成分的影响非常明显,为获得同等压实度,细粒土所需的压实功能较粗粒土高,除此之外,细粒土的压缩指数也高于粗粒土,表现出较强的压缩性;随着土样压实密度的增加,粗/细土样的压缩曲线逐渐靠拢,粒度成分对压实功能影响逐渐减弱;土样卸荷时回弹指数随干密度的增加而增加,受粒度成分的影响不明显;高压实ρ(下标 d=2.0g/立方公分粗粒土样在7 MPa的轴向应力下饱和时,体积发生明显的塌陷现象,饱和后土样的压缩指数小于饱和前,而回弹指数则较饱和前高。

Based on the analysis of the mechanism of robot manipulators, a trajectory tracking controlling research model is first built up with ADAMS, and its mathematical model is formulated through the study of robot kinematics and dynamics. After the modeling errors are analyzed in practical robotic systems, a conception of centralized error is brought forward according to the theory of weighting functions. In the case of modeling errors' exist, the robotic uncertain model is derived by introducing an auxiliary control variable into inverse dynamic analysis. The control strategy of robust exponential convergence is applied to the robotic uncertain model, the applicable conditions and the applicable controller with this application are presented. The stable control effect under three main model uncertainties (parametric errors, joint disturbs, joint frictions) are systematically studied on the previously built research model. The problems of robust exponential convergence controller which often results in unstable output and so produces a large relative error when the input trajectory is in a small range are resolved by adjusting the control parameters based on the controller's structure.

During aging, Gastel index which is sensible to aging condition decreased with increase of aging temperature and aging time. As the same time, the exponential relationship between the change of viscosity and aging time was discovered. Both the gastel index and the aging index can be used to evaluate the aging resistance of the colored paving asphalt.
