May 23, 2002 · Compared with irredundant flexible manipulators, a FRM possesses additional possibilities during point-to-point trajectory planning due to its kinematics redundancy. A trajectory planning method to minimize vibration and/or executing time of a point-to-point motion is presented for FRMs based on Genetic Algorithms (GAs).
What is claimed is 1. In a concrete pump of the type having a flexible hose for receiving concrete to be pumped therethrough, and having powered rollers advancing along said hose to squeeze said hose for collapsing it in the pumping process, and having means extending along said hose to engage said hose for placing said hose in its uncollapsed condition when said rollers have passed along said
Open and closed center hydraulic systems Open center point for our web-based M-Power. Within M-Power you can make power pump, directional control valve, and actuators to move and control fluid in order to accomplish work. In every hydraulic circuit, we start with
Booms of modern mobile concrete pumps are vulnerable to elastic vibrations due to the light-weight construction. Although these vibrations can be effectively damped with appropriate controllers, the residual movement of the tool center point (TCP) during the pumping process is still uncomfortable for the workers guiding the end hose.

The Open Mechanical Engineering Journal, 2008, 2, 84-92 84 Open Access Study on Automatic Spray of Distribution Boom System of Truck- Mounted Concrete Pump Shu-Wen Zhou, Li-Xin Guo* and Si-Qi Zhang College of Mechanical Engineering and Automation, Northeastern University, Shenyang 110004, China Abstract: Truck-mounted concrete pumps have been adopted in many construction projects.
Time-optimal fold-out of a mobile concrete pump Project description. Mobile concrete pumps are used on construction sites to transport concrete from the cement mixer to the formwork. Such machines typically comprise a pump and a boom equipped with concrete convey pipes, see Fig. 1.
concrete to form the inclusions. Besides the necessary drilling equipment there has to be a concrete pump which feeds the upper side of the drilling tool through flexible hoses. Figure 4a. Diagram of the typical point of the hollow auger for displacement rigid inclusions. Figure 4b. Point of the hollow auger for displacement rigid inclusions
(such as pumps and turbines). (d) Excessive stresses in the supporting (or restraining) elements. (e) Resonance with imposed or fluid-induced vibrations. (f) Excessive interference with thermal expansion and contraction in piping which is otherwise adequately flexible. (g) Unintentional disengagement of piping from its supports.
