In today's competitive market, all manufacturers attempt to improve their maintenance policy in order to decrease the cost of failure and increase the quality of products, but most of these attempts do not consider the role of humans involved in a manufacturing system. Human resources are the main factor in manufacturing that has an undeniable effect on products quality, machines reliability, s...

The hydraulic system of mobile garbage compression equipment was studied according to its actual working conditions. A simulation model of the hydraulic system was established with AMESim software, and the speed and acceleration of the piston rod were simulated. Simulation results show that the designed hydraulic system can achieve the action requirements. The experiment also shows the similar ...

Reciprocating compressors of the crosshead design have sealing elements around the piston and piston rod. These seals can be of lubricated or nonlubricated design. This paper will give details about our R&D-work for dry running piston rod sealings or packings for high pressure applications. Starting with an overview of packing design some details are given about tribological tests. Measurements...

The synergistic control of resistance reduction and sealing poses challenges to enhancing the rapid dynamic response ability servo hydraulic cylinders; key solving this problem is effectively controlling gap value. In study, a micro-variation between cylinder piston based on disadvantage conventional seals, constant lip seals was constructed; MSMA assist support blocks were designed form seal s...

A one-dimensional Casimir piston for massless scalar fields obeying Dirichlet boundary conditions in high-dimensional spacetimes within the frame of Kaluza-Klein theory is analyzed. We derive and calculate the exact expression for the Casimir force on the piston. We also compute the Casimir force in the limit that one outer plate is moved to the extremely distant place to show that the reduced ...

This White Paper describes the separate features of MES and Advanced Planning & Scheduling Systems and shows how an integrated MES/APS solution should work. It shows how an integrated and collaborative approach will help to significantly increase the benefits that would be obtained compared with a separate and independent implementation of these systems on a Make-to-Order plant.
