One, preface Combine a tool machine work in, the varieties which slip a size of sport speed and direction andthe load bear all influence degree differently it work in the work enter the on the stage load of suddenly disappear causable of ex hurtle and load ofthe period variety cause of the sport gravamen be steady, all is processed the surface quality ofpiece the influence, severity hour will cause the knife according to tool machinefactory in Dalian, the author adopts power key to match diagram and the analytical method establishment of the appearance space to bine the new liquid that the tool machine slips apedestal to press to drive system a from adjust to carry on the back to press to adjust soon dynamic state mathematics model of a calculator numeral to imitate really and slippery the pedestal produce ago hurtle and exercise not steady reason and main impact factor, in order to improvement slippery the dynamic state characteristic of pedestal. Two, dynamic state mathematics model The liquid which bines tool machine to slip a pedestal presses to drive system a from adjustto carry on the back to press to adjust soon the work principle diagram of system,such as diagram I, to system is the work circulation which uses to plete the work enter a stop a back quickly.When slippery pedestal work enter, 34 change to be placed in diagram to show a right toward the valve, the oil pump of provide hydraulicpneumatic dint under thefunction which over flows valve look like ground to keep Heng settle, the oil39。s liquid flows through to change toward the valve and adjust soon valve juniors into the oil urn of 2 have no a pole chamber, push slippery the set be left shift。In the meantime, oil urn the pressure oil that if there is pole chamber, eject through from adjust to carry on the back to press valve and change to flow to return to fuel tank toward the this process, two oneway valves with overflowed to flow valve and always don39。t change original work that system so of plications not line system, for the sake of easy to study its dynamic state characteristic, build up a reasonable simple dynamic state mathematics model which only emphasizes to consider main impact factor is particularly important[1][2].Know from the theories the analysis with experiment the research:That system of process time be soon that the process which is far larger than to adjust valve is soonhorary, oil urn have no the pole chamber effectively accepts to press area very greatly, adjust soon valve export discharge of super adjust a reflection in a mome nt is slippery pedestal sport speed of the variety be pimping[2].For openning widely and going deep into dynamic state characteristic of study the system, make research work can on the microputer availably carry on, this text to original model[2] do further simplification, on thesupposition that adjust soon the valve outputs in the whole transition process of system Hengsettle of discharge, treat it as to flow a , the structure sketch plan of the dynamic state model of system such as figure 2 show, it from oil urn, slippery set, carry on the back to press valve and unite connector39。s road39。s etc. to constitute from the text in use of sign asfollows: S 1flow a source, then adjust soon valve export discharge。 Selthe slippery set glide friction Selthe slippery set glide friction C5, C6the etc. effect liquid of tube road permit: R5, R7take care of an etc. of road effect liquid Zu。 V3, the V4oil urn has no pole chamber and has a pole chamber the contents to accumulate。 P3, the pressure which have no pole chamber and have a pole chamber of the P4oil urn Fthe slippery set bear a load, Vslip a pedestal sport this literary grace hard working rate key matches diagram and appearance space to fold a method establishment sport mathematics model of the system for cent. Power key39。s matching diagram is an effect to flow diagram, it is the energy which presses system to deliver a way, take actual structure as foundation, the function which uses concentration parameter the of sub system relates to an abstract earth39。s surface to show for the Zu a dollar Rand permits sex dollar C and sensitive faculty dollar I of three kinds of 3 function thiskind of method sets up a mold physical concept clear, bine the appearance space analysis method can pare to accurately describe with analysis line system, that method is in the hour the area study plications the line system dynamic state characteristic not of a kind of valid of method. According to from adjust to carry on the back to press to adjust soon the main characteristic ofeach ponent of system and set up mold rule[1], get figure 3 show of the power key of system match half arrowhead on the key in diagram means that the power fly to, 2 which constitute power change the quantity be a dint to change to measure(hydraulicpneumatic P or function dint F) and flow to change to measure(disch
