Human motion recognition is a challenging task, especially when motion capture data is huge. Existing approaches for this task focused mainly on how to extract features from motion capture data to achieve high recognition performance. However, due to the presence of redundant features and the high dimensionality of data, these approaches may not achieve the optimal performance. In order to rapidly...
The catalytic steam gasification of municipal solid wastes (MSW) for syn-gas production was experimentally investigated in a combined fixed bed reactor using the newly developed tri-metallic catalyst. A series of experiments have been performed to explore the effects of catalyst presence, catalytic temperature, catalyst to MSW weight ratio (C/M) and steam to MSW ratio (S/M) on the composition and...
Considered the effect of temperature on the main bearing, the temperature distributions of journal, bearing and lubricant were calculated, and the thermo hydrodynamic performances of the main bearing were analyzed by solving generalized Reynolds equation, energy equation and solid heat conduction equation, etc. The results show that the bearing has obvious effect on the temperature of lubricating...
This paper studies the nonlinear vibration of robotic manipulator with parallelogram hinged mechanism while it motioned in plane. The controllable motor and the hinged mechanism are studied in an integrated manner, and the electromechanical coupling nonlinear dynamic equation of the system is established by finite element method. The relation between the nonlinear vibration of the system and the parameters...
Traditional multi-cylinder engine crankshaft stress calculation would generally use simplified continuous beam model, but the accuracy is not high enough. The paper presents a whole dynamic model for analyzing the dynamic behavior of a diesel engine crankshaft by means of three-dimensional FEA. Based on the finite element commercial software ANSYS, an overall three-dimensional model of the four-cylinder...
Based on the average Reynolds equation, this paper studied the friction and lubrication of piston skirt-cylinder and piston ring-cylinder. Combined with the piston secondary motion equation, an coupling model of cylinder - piston - piston ring oil film lubrication system is presented. The model considered the effects of piston ring lubrication characteristic on piston secondary motion and the effects...
Because of automated guided vehicles (AGVs) routing flexibility, they have been used in many manufacturing systems, especially those in which parts with diverse and complex processing routes are made. This paper introduces the design of an material handling flow path control system in a partitioned zone through the timed Petri Nets. The initial requirements of a system specified with sequence diagrams...
