Research and development (R&D) investment is a kind of strategic behavior filled with high uncertainty and risk. Currently domestic relevant research on the R&D input value mostly emphasizes the enterprise R&D investment impact on shareholder wealth, and less about the trade-off between R&D investment impact on bondholders and shareholders. The present study uses revealed...
Civil Experimental System consists of electric-hydraulic servo-controlled machine and the data recorder in which the recorded data are saved. In Electro-hydraulic servo controller, a exterior trigger signal is used to remote control the data recorder working, and the problem of simultaneously data recording is solved by on-line processing of servo testing machine and data recorder, which quicken the...
According to the operating principle of the electric load simulator, the mathematic model of its actuating mechanism is built. Then, the joint stiffness between the electric load simulator and the rudder is analyzed which can impact the system performance. Based on the analysis result, the low joint stiffness should be chose under the condition of satisfying capability requirement of the system closed...
