Analysis on determining maximum amplitude of model fluctuation pressure on training stoplogs gate with varying elevation intake;

According to the inflow of upstream in the spillway bay#1 closure tests of the Merowe dam project in Sudan,the spillway bay#1 closure procedure test is required to establish flow characteristic parameter at various opening under the condition to maintain a water discharge of 500 m3/s downstream through control bottom opening of upstream stop log gates.

Erection method of laminated beams of boiler structure;

In order to accurately analyze the differences on load carrying ability among laminated beam,laminated beam with wedges and beam as a whole of the same dimension,this paper sets up a model of flection of laminated beams with rectangular cross section by taking advantage of Winkle s foundation assumption method and electric testing technique.

A simple analytical model for simply supported laminated beams is established based on the characteristic of beams under stress.

The main advantages of the gyroscope are that the mechanically and electrically coupling between actuation mode and detection mode are reduced through independent folded beam and oscillator mass.

In this article,a kind of 2 D capacitive silicon microaccelerometer with the folded beam is designed and its main axis stiffness is caculated using force method,which provides the basis for studying dynamic characteristics of this kind of microaccelerometer.
