Due to the high corrosion and chemical resistance, the fiber reinforced polymer( FRP) materials are increasingly being used for the tall slender thin-walled structure, such as smoking desulfuration absorber tower. The properties of this slender fiber reinforced polymer absorber tower are: the aspect ratio is 2.5 and the ratio of the wall thickness to its radius is taken to be 0.0038. So the seismic...
The application based on single-chip computer (AT89S52) in agriculture and landscape irrigation system was described, and a kind of time control irrigation system was designed. The system can set working time and can automatically irrigate fields when unattended. if the end of the setting time, the system can cease irrigate and alarm automatically. It fulfilled the demand through local debug and was...
Due to their high corrosion and chemical resistance, glass fiber reinforced plastic (GFRP) materials are increasingly being used in the construction of industrial chimneys. The design of a chimney is governed by dead loads, wind loads, thermal loads and seismic loads. In this paper, the finite element model of a 60m high FRP chimney with complex connections is established using finite element software...
A finite element model of carbon fiber reinforced polymer (CFRP) pressure vessel with aluminum liner is established by ANSYS finite element software. The outer filament wound fibers are overwrapped by both hoop winding and helical winding methods. The safety is vital because of high working pressure which is more than 35MPa. In the modeling process, the number of filament winding layers is treated...
Due to their high corrosion and chemical resistance, glass fiber reinforced plastic (GFRP) materials are increasingly being used in the construction of industrial chimneys. In this paper, the finite element model of a 60 m high GFRP chimney with the diameter of 3 m is established using finite element software ANSYS. The cylindric chimney, steel supporting frames and the two anchor cables are meshed...
The external penalty function methods transform the basic optimization problem into alternative formulations such that numerical solutions are sought by solving a sequence of unconstrained minimization problem. This paper uses the external penalty function method to solve constrained optimal control problems for optimization design of underground reinforced concrete penstock. Through establishing...
Resource optimization plays vital role in wireless Ad hoc network since such type of network are not having resources in ample amount. Working with limited resources like bandwidth, battery power, buffer space etc. create problems during data transmission in the network. Battery power may decrease the overall life time of a network. In this paper we have proposed two algorithms Select_Node. Select_Node...
