PRIMARY RESONANCE ANALYSIS OF ARM SYSTEM UNDER BOUNDED NARROW⁃BAND EXCITATION by YANG ZhiAn, MAN ZhiJun, LIU WenYang

“…By using multi⁃scales method,the first primary resonance of the human arm and vibration mechanical coupling system under random narrow⁃band excitation was analyzed,and the two⁃degree⁃of⁃freedom nonlinear dynamic equation of the arm system was established.The first primary resonance amplitude frequency response equation and Ito stochastic differential equation of the system were solved in turn.In order to study the distribution law of variables under random vibration,the approximate expressions of the expectation and mean square value of the first primary resonance random mean square response were calculated using the moment estimation method.The influence of the parameters of the human arm system on the primary resonance was obtained through numerical analysis.The results show that the mean square response curves of the first primary resonance have the same topological structure as their amplitude⁃frequency response curves,and the mean square value of the primary resonance amplitudes and the resonance region increase with the increase of the amplitude of the external excitation,while the increase of the system damping will reduce the mean square value and the resonance region.The change of nonlinear stiffness coefficient has little effect on the system.…”

内啮合齿轮泵隔离装置的平衡 by 郭善新, 余广炽, 关翔锋

“…In order to achieve a higher volumetric efficiency of an internal gear pump at higher pressures,a new isolation device with a compensating function in the diameter direction was developed.The device used a technical method of expanding high pressure chamber inside the pump.In order to obtain a better balance for the isolation device,according to the pressure distribution law of the transition zone,the calculation formulas of hydraulic pressure,the compensation force and the supporting force of the crescent block in the transition zone of the crescent block were derived,and then the equilibrium constraints of the device were established.The transition zone was enlarged until only two gear teeth.As an example,the fmincon tool was used to obtain the optimum center angle of the compensation cavity,and the force changes curve was obtained by MATLAB simulation.When an internal gear pump with a theoretical displacement of 50.8 ml/r was carried out under the condition of input pressure of 0.3 MPa,output pressure of 21.8 MPa,at 50℃ ±4℃,and the results show that the volumetric efficiency can reachs 94.3%.No abnormal wear was observed.…”

Slant Angle and Its Influence on Rock Cutting Performance by Yong Sun, Xingsheng Li

“…The slant angle of a pick is determined by its tilt angle and the inclination angle of the rock surface. The calculation of the slant angle is presented. A series of laboratory rock cutting experiments were conducted to investigate the influence of the slant angle on cutting force and rock fracture pattern, and two new findings were made: (1) the rotational angle of the groove cut by a tilted pick was possibly different from the tilt angle and (2) all forces on a pick increased significantly with the increase of the slant angle. …”
