Based on elastohydrodynamic Lubrication theory (EHL), the EHL oil film thicknesses and those distributions for two operation cases on meshing line were calculated: one case is the sun gear as the driving gear and another case is the ring gear as the driving gear in the Planetary Gear Transmission. From the graph, gear lubrication can be reflected by the gear mesh lubrication at the node. The worse...
Based on elastic hydrodynamic lubrication (EHL or EHD) theory, an EHL model of the internal meshing between ring gear and planet gear in Planetary Gear Transmission was established. The EHL oil film thicknesses and those distributions for two operation cases on meshing line were calculated: one case with the sun gear as the driving gear and another case with the ring gear as the driving gear. The...
Based on the movement principle of parallel mechanism, to construct a new 3-DOF parallel mechanism which has one translation and two rotations, it is analyzed the theory of the position, velocity and acceleration of the parallel mechanism. Then it is applied to the design of the car seat vibration, a simple model of which is also done. Finally, using ADAMS software to build the simulation models of...
The revolute outputs effected by the clearances of joints which are caused by the inaccurate precision of processing and error of assembly are analyzed at first, then in order to illustrate the problem the simulation of a kind of parallel mechanism named 3-PRUR is also done in Pro/E and Adams software. At last a kind of compliant revolute joint called split-tube flexural pivots based on the principle...
In China and the rest of the world, family businesses as a unique mode of operation in the economic development of countries has played an important role. This paper studies on the basis of family business research in our country, then bases on the principal - agent relationship, a mathematical model by maximizing the return on the family business is analyzed. Analysts believe that the family business...
Abstract-It is designed a new fully compliant 3-RRRP parallel micro-displacement vibration actuator. All the joins in the traditional 3-RRRP parallel mechanism are changed into fully compliant ones. Theoretic analysis shows that the fully compliant mechanism will transfer into micro-displacement vibration actuator if adding single freedom PLZ vibration actuators to the traditional inputting components...
With the rapid development of the information technology and continues improving of net economy, modern manufacturing enterprises have gradually changed their business model from the traditional into Internet-based. But the traditional ERP system serviced in enterprise mainly focused on optimization of internal process of business, it also made enterprises can not exchange information effectively...
