Strategic Study of CAE 2001, Volume 3, Issue 11, Pages 70-73
With secondary regulation, a novel hydraulic transmission technology, the secondary regulated loading system described here is oriented to rotational speed experiment of reduction gear or material. In this paper, the hardware structure of the system is introduced with specialties of the transducers, electro-hydraulic servo valves and the computer data collector used. Then, signal-adjusting circuit between computer control system and transducers or servo valves is designed. Next, a VC+ + control program under Windows operating system is worked out. Experiments on Step, Rectangle, Ramp and Sine Responses of the speed sub-system are done under alternative oil pressure and load. Finally, some meaningful results are given by contrasting the experimental curves.

Strategic Study of CAE 2000, Volume 2, Issue 7, Pages 47-54
Secondary regulation is novel hydraulic transmission technology which possesses many outstanding advantages, such as convenient controlling, easily composing network components just like that in an electric system, and even simpler energy recovering and regeneration than in an electric system. Researches in secondary regulation technology will have no hesitation to enlarge the application scope and enhance the product competitive power of the hydaulic system. Torque servo loading system is a typical equipment in secondary regulation research with; briniant application future. In the paper, by modeling a secondary regulated torque loading system in detail, some nature dynamic characteristics of secondary regulation technology is analyzed. Finally, a computer control system of the secondary regulated loading equipment is established and several experimental curves prove the theoretical analyzing results.
