Static Performance

This paper presents a theoretical study of the performance of constant power operated swash plate pumps equipped with hydromechanical controllers incorporating either pivoted levers or two feedback springs. Mathematical models of these controllers are derived and used to simulate the static and dynamic characteristics of a small pump of 40 cc/rev geometric volume. Results show that the controller with the pivoted lever renders better static and dynamic characteristics compared to the controllers with feedback springs. Results also show that changing the power through varying the lever arm length is preferable than varying the valve spring initial compression, when the dynamic characteristics of the pumps with controllers of pivoted levers are considered. The effect of the valve spring initial compression on the static performance of a pump incorporating a controller with two feedback springs is also investigated.

In order to get the better electromagnetic characteristics of the micro digital valve, the larger electromagnetic force should be obtained in the smaller electromagnetic structure. The electromagnetic force directly determines the electromagnetic properties of the miniature digital valve. The electromagnetic force test is studied in the paper. The results of electromagnetic simulation results are basically consistent with the experimental results. The simulation model is reliable and accurate. The dynamic simulation results show that the dynamic characteristics of the miniature digital valve meet the requirements of the digital hydraulic technology. Design of the new micro digital valve is reasonable.

Static and dynamic characteristics of a two stage relief valve have been studied theoretically and experimentally. The governing equations of the valve have been derived and sensitivity analysis was performed by digital computer simulation on the valve response characteristics based on the established dynamic equations of the motions of the valve. From this study, significant parameters on the valve response were identified, which can be modified to improve the dynamic characteristics of the valve. Subsequently, experiments were performed with a specially fabricated Vickers type pilot relief valve. The results showed fair agreement with the simulation results, thus proving the validity of the model.

The paper reports on the results of the studies of static and dynamic characteristics of 4H-SiC drift step recovery diodes (DSRDs) assembled in diode stacks. Switching performance of single dies has been simulated and experimentally confirmed. It was established that the switching process is determined primarily by the incomplete ionization of acceptors in 4H-SiC and by the bandgap narrowing in heavily doped emitters. Based on the simulation results the optimized die size has been selected. For DSRD stacks of 4 and 8 dies I-V and C-V measurements are reported. The stacks were dynamically tested in a special oscillator circuit. Repetitive voltage pulses of 10.5 kV with the leading edge length of 900 ps were demonstrated.
