Since the artificial bee colony (ABC) algorithm had drawbacks of slow convergence and easy to fall into local optimum, a modified optimization algorithm called fast artificial bee colony (FABC) was introduced by setting the selfadaptive scaling factor and replacing the traditional roulette wheel selection model with the fitness sorting method. The suitability of FABC for geometry optimization of structures was tested on four truss examples with discrete variables, compared with other optimal algorithms of GA, ACA, HPSO and GSO. The results show that FABC had advantages over other algorithms in convergence accuracy. 〖JP2〗Furthermore, due to the simple algorithm structure, both algorithms of ABC and FABC can apply to solving other optimal issues.

Lunar soil，as a kind of discrete mediums， whose mechanical behavior is not just affected by external factors， but by the interactions and constraints between the soil particles. The mechanical property of continuous mediums is difficult to simulate， and the discrete element method(DEM) as a numerical way to the analysis of discrete medium can be used to simulate the mechanical behavior between devices and the lunar soil. This paper was based on the former analysis of the drilling process on moons surface by Soviet Luna24.Analyzing the process of drilling and building the lunar soil modal with the discrete element software PFC3D was the first step， then we defined the lunar soils constitutive model by giving the particle contact stiffness， coefficient of friction， adhesion coefficient and so on. We contrasted the energy consumption and drilling resistance by stimulating the process of drilling. The results show that the screw pitch and rotate speed have great impact on the energy consumption and drilling resistance. The bigger the screw pitch is and the higher the speed is， the larger the energy consumption and drilling resistance are， and they have a linear relation. The results are conducive to the lunar surface sampling mechanisms design and optimization．

The effect of crease stiffness was discussed about force and deformation. Some suggestions are brought up for analyzing and simulating flexible structures which broad up the range for spring-mass model.

The shield machines thrust system can be seen as a vibration system. The computational formula of the vibration response of the nondamping system to initial conditions was derived by using modal superposition method in order to study the response of the EPBs thrust system to initial conditions， and based on which the 5 degrees of freedom nondamping thrust system vibration model was built considering the foundation spring. And then vibration response to initial conditions is derived that initial angles around the X-axis and Y-axis have great influence on the attitude of the thrust system， and the deflection of the thrust system will be up to 2753°when the initial angle is 1°， that makes a great challenge to adjust the angle of the shield machine attitude， and even the shield will deviate from the planned route and be unable to complete the excavation work.

In view of the serious high speed slide of a mining friction hoist， aiming at calculating the linings thermostress accurately， the most commonly used lining G was studied on thermal mechanical analyzer（ZRPY-300）， and the effect of load（0-10 N） and heating rate（1-5 ℃/min） on coefficient of linear expansion were analyzed. Experimental results show that the coefficient of linear expansion increases with the temperature increasing under the certain load and heating rate， and when the temperature reaches to 120 ℃， the curve occurres transition and then decreases gradually. When the temperature reaches to 195 ℃， the curve occurres the second transition and then increases again. The coefficient of linear expansion is obviously with the load increasing under a certain heating rate， and the coefficient of linear expansion is complexity with the heating rate increasing under a certain load. Finally the fitting equation is obtained by the multiple regression analysis. Based on this study， the experiment results can supply the basic data for the design of highperformance lining．

In order to solve the problems in aircraft rudder loading system such as strong interference， coupling and so on， we analyzed the characteristics of disturbance torque in passive loading system.For high order differential controller with feedforward compensation method in physics are hard to realize and models are mismatched, we put forward a composition control method based on the combination of the feedforward compensation structure and FCMACPID control algorithm. In the design of feedforward compensation controller，we used the loading motor output shaft angular velocity as the compensation input， this kind of compensator not only effectively eliminated the surplus torque， but also reduced the whole system as well as the compensator order.

Simulation results show that the compensation controller can effectively eliminate the disturbance, and the system can quickly and accurately track the load spectrum．
