The Research On Electro-hydraulic Driving Control System On New Type Of Dynamic Compaction Machine

The paper narrated the strong rammer machine's operating feature and the domestic and foreign state. Through strong rammer maneuvering force system in various part of work by the energy consumption analysis, then conducts the power match control research in above the strong rammer machine hydraulic system design's foundation to the strong rammer machine travel system, in establishes the strong rammer maneuvering force system mathematical model above the foundation, the application fuzzy auto-adapted PID control policy conducts the simulation research in the strong rammer maneuvering force system,which has been manifested its superiority and the usability.The control's key point of the strong rammer machine travel systems is the variable displacement pump - engine's power match control, the paper use the same speed and consistent achievement match basis, it has been divided the strong rammer machine different working pattern through the computation, regarding different pattern application corresponding energy conservation control policy. The paper simultaneously proposed the hydraulic pressure cooling system energy conservation control policy, and it may been taken an aspect of the hydraulic system energy conservation research.Finally, the paper carries on through energy conservation controller DSP2812 to the above theory realizes, by 2812 controllers, which carried on the software and hardware design primarily to the travel central controller, and correspond through the corresponding experiment which uses in the actual system's software and hardware carrying on the confirmation, and it has provided certain theory and the experiment foundation for the strong rammer machine energy conservation controller's design.
