Reliability analysis of dynamic accuracy for the heavy-duty machine tool segmented beam
نویسندگان
چکیده
The dynamic reliability of the heavy-duty CNC machine tool beam is directly related to machining accuracy which challenging maintain because gantry structure. It important evaluate and components, especially beam. This research investigated a segmented heavy by studying surface morphology joint surface. mechanical model single asperity established based on finite element method. elastic plastic stage deformation boundary values are obtained, contact full using Gaussian distribution characteristics. sectional developed transforming parameters verified field modal experiment. Additionally, proposed used analyze impact vibration accuracy. results revealed that highly reliable.

Heavy duty vehicles have a great share on fossil fuel consumption and greenhouse gases in the world, while they waste two third of chemical energy of fuel. On the other hand, simplicity and long life of thermoelectric generators (TEGs) are considered more and more to convert thermal energy to electrical one. In this paper a TEG designed in the exhaust system of Renault Midlum 195 Dxi Engine. Th...

Study on the Dynamic Performance of Heavy-duty Forging Manipulator
Cooperating with heavy forging press, the heavy-duty forging manipulator is used for handling the workpiece during the free-forging process. Therefore, the size accuracy of the forgings is related to the dynamics performance of the forging manipulator. This paper aims to study the dynamic performance of DDS heavy-duty forging manipulator. The kinematics model is firstly built to predict the tra...
