Three, slip to hurtle before the pedestal Slippery before the pedestal hurtle phenomenon is what function at slip the load of on the stage suddenly disappeared( if drilled to deeply work circumstance) this process, the variety which slips two chamber pressure P3s and P4 of the load F, sport speed V, oil urn of pedestal can from the figure 4 imitate true result the slippery pedestal evenly and soon exercises under the function of the load, the oil urn has no pole chamber oil liquid pressure came together a great deal of energy in the oil loading to suddenly disappear, that chamber is hydraulicpneumatic to immediately and quickly lower, the oil liquid turns into the process of lowpressure Tai toward system to release a lot of energies from the high pressure Tai and cause slippery pedestal the high speed pounds at , slip a pedestal of ex hurtle to make an oil urn to have a pole chamber the 4 oil liquid is press to cause to carry on the back to press to go up, thus the depletion drop one part of energies in the system, to slippery pedestal of front blunt certainly repress a see, in the system study, from adjust to carry on the back entrance pressure of press the valve and be subjected to an oil urn two chambers hydraulicpneumatic prehensive load a disappeared moment, from adjust to carry on the back the pressure of press the valve quickly rises, and stabilize the number which starts to carry on the back to press at the beginning in the Gao the diagram it is thus clear that, from adjust to carry on the back to press to adjust soon the system is in a twinkling load to disappear oil urn carry the range that the pressure go up on oil urn39。s back big in traditionally adjust soon system, so, its oil urn energy which have the oil liquid in the pole chamber absorption many。Result, slip a pedestal of ex blunt the quantity adjusts system to soon want than the tradition small be close to 20%.It is thus clear that adoption from adjust to carry on the back a Chuang to adjust soon system conduct and actions to drive the slippery pedestal of system to have good characteristic in the aspects of hurtling before repress, among them from adjust to carry on the back to press valve to have very your work to use. Four, slip the exercise of pedestal steady While regarding as a load period of used for the slippery on the stage variety(if the Xian pares to process a circumstance), the sport speed which slips a pedestal wants to produce certain。 order to process the request of quality at assurance, have to possibly let up its speed motion out from the convenience discussed a problem, suppose a load by the sine wave regulation variety, get thus of numeral imitate a true result such as figure 5 showed from this that system and traditionally adjust soon system to have same variety regulation with very close of reason is that the variety range of load isn39。t big, oil urn two chamber pressures also more and greatly didn39。t change, end cause from adjust to carry on the back a function of press the valve not enough obvious. Five, improve measure Study result enunciation, with from adjust to carry on the back to press to adjust soon system for drive the slippery set of system, its dynamic state characteristic surpasses to traditionally adjustsoon to reduce the ex blunt quantity of slippery pedestal, must be load the disappeared moment quickly raises an oil urn have a pole chamber of carry on the back pressure。Want to raise the exercise of slippery pedestal steady to need to increase system of rigid, the main measure lies in the physical volume which lets up an oil 176。from the structure of the system, the oil urn has a pole chamber to have with the row pipeline one very big capacity and show such as the figure 6 of the existence delay with Shuai reduce from adjust to carry on the back a function of press the valve, also lowered 5 system on the other hand of rigid, it limitted to hurtle characteristic and exercise the further improvement of steady , the improvement slippery pedestal dynamic state characteristic can carry on from two paths:Namely change an oil urn capacity and change from adjust to carry on the back to pressvalve structure parison passed one true calculation and result of the imitate of parameter of the system structure can get:When oil urn have pole chamber and row pipeline thecapacity V4 together has no pole chamber with enter pipeline the capacity V3 of ratio from original of c
