Wu REN, Yunxin WU, Zhaowei ZHANG
Frontiers of Mechanical Engineering 2013, Volume 8, Issue 4, Pages 360-366 doi: 10.1007/s11465-013-0280-8
Mobile concrete pump boom is typical multi-body large-scale motion manipulator.A dynamics model of a mobile concrete pump boom is established based on discrete time transfer matrixThe boom system is divided into sub-structure A and sub-structure B.Sub-structure A is composed by the 1st boom and hydraulic actuator as well as the support.So it is suitable for mobile concrete pump boom real-time monitoring and dynamic analysis.
Keywords: multi-body mobile concrete pump boom discrete time transfer matrix method (DTTMM) kinematic dynamic tip
Elliptical lobe shape gerotor pump design to minimize wear
Mohammad Reza KARAMOOZ RAVARI
Frontiers of Mechanical Engineering 2011, Volume 6, Issue 4, Pages 429-434 doi: 10.1007/s11465-011-0247-6
The gerotor pumps are the most important parts of mechanical equipment that have a vast number of applications in industries and automobiles. Because the gerotor pumps cannot be adjusted for wear so it is important to reduce the wear as much as possible. In this paper first mathematical equations for elliptical lobe shape rotors profile and curvature of them have been derived and then Specific flow and wear rate proportional factor (WRPF) have been formulated. To reach the minimum wear in rotors teeth, the ellipse shape factor is changed for each value of number of outer rotor teeth in a feasible range and wear rate proportional factor has been resulted. Also in order to have better comparison specific flow has been presented. The obtained results have been compared with circular pumps with similar geometrical parameters and show the significant improvement in wear of the rotors with negligible changes in the specific flow.
