This paper presents the means to raise propelling motor's power output of a certain torpedo from the view of the reliable direction change, turn speed increase, shaft's mechanical strength, allowable temperature rise and cooling medium on the basis of its structural parameters.
It can not only regulate the moving velocity of the actuator, but also simplify the hydraulic system of the base machine, improve the smoothness of direction change and enhance the operation performance of the base machine.
This paper introduces the harm to the hydraulic system which is caused by the hydraulic impact, analyses the reasons of the hydraulic impact from the aspect of the sudden velocity change of liquid, the stop or direction change of the movement equipments and so on, puts forward the methods of decrease and elimination, and provides the basis for the hydraulic system design.
The analysis on the eliminate the soft breakdown which emerges when X axis approaches the inverse direction change in the processing of the digit-controlled machine tool is a very effective method to fix breakdowns in digit-controlled machine-tools.
The analysis on the eliminate process of this soft breakdown in the processing of the digit-controlled machine tool which appears when X axis approaches the inverse direction change is a very effective method to fix breakdowns in digit-controlled machine-tools.
The furnace conbined with the regenerative heat recuperating system and the change over combustion system,can preheat the air and gas at the same time to 1 100 ℃,with the fume exhaust temperature of less than 150 ℃,50% energy saving and 30% output increasment and the pure gas from blast furnace may be used in high temperature industrial furnaces.
The paper presents the technical measures taken to improve 12E390VA type diesel engine by means of changing to usa newly matched VTR354A tubochargers and applying a simplified changeover system,which has further improved engine performance and operating reliability and resulted in a reduction of S.F. C. by 6g/PS.
For unbounded operators A, B and C in general, the commutation relation [A, B] =
However, a ripple current occurs in the inactive phase due to the diode freewheeling during the non-commutation period in the traditional pulse width modulation (PWM) methods, which aggravates the torque ripples.
A new PWM method is proposed in this paper to eliminate the diode freewheeling during the non-commutation period in the inactive phase.
An algorithm is designed for computing "throughput" service quality characteristics of circuit-switched re-routing networks with regard for the influence of undetected failures in commutation devices if crankbacking is used for switching.
It is shown that an arbitrary grouped p-element permutation can be implemented in a conflict-free way through the commutation of channels on the double p-ary multiring or the double p-ary hypercube.
In this paper a new shape similarity measure of linear entities based on the differences of direction change along each line is presented and its effectiveness is illustrated.
Matrix Green's function allows us to procure an immediate result for position and direction change of the victim antenna.
Correlation dropped by nearly 50% following a direction change of 90° or more, suggesting that accumulation is reduced but not abolished by large changes in movement direction.
The subjects reacted as quickly as possible to the direction change.
Further, unlike autocorrelation, which generally identifies lags close to the true lag, intra-multiplicity can erroneously identify lags anywhere in the time series and commonly results in a direction change of the correlation (i.e.
Using numerical simulation, the parameters of the injected beam were optimized and the conditions for the absence of particle loss upon a changeover into the acceleration mode and subsequent acceleration to the maximum energy were determined.
By the example of OAO "Krasnodarekoneft'," the changes that occurred in the corrosion state of an atmospheric tower of a primary oil refining section upon a changeover to more corrosive crude oil are examined.
The obtained relationship predicts a changeover from the "square root" law in the charge region where the average distance between ions lis smaller than the ionic-atmosphere thickness 1/κ, to the "cube root" law, at l>amp;gt; 1/κ.
Heating samples above ～670 K is shown to result in a changeover of the conduction type from semiconducting (p-type) to metallic.
The mentioned changes are associated not only with the acceleration of gold dissolution in the presence of chemisorbed sulfide ions but also with the changeover in the mechanism of this process.
