1、附 录附录1英文原文Combine tool machine a slippery pedestal the research of the dynamic state characteristic【Summary】this text make use of power key to match diagram and appearance space analyticalthe method hurtle and exercise a steady sex problem to carry on analysis and study towards combining tool machin
2、e slip pedestal of ex-ly, the liquid which builds up a slippery pedestalpresses to drive system a from adjust to carry on the back to press to adjust soon dynamic statemathematics model of system.Pass a calculator numeral to imitate really, hurtle and exercise notsteady reason and main impact factor
3、 before analyzing a slippery pedestal a creation.From in get, if reasonably design a liquid to press an urn with from adjust to carry on the back to press toadjust structure size of press the valve, can make the dynamic state characteristic of slipperypedestal shown a Zhao improvement.One, prefaceCo
4、mbine 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 function.Especially in the work enter theprocess.Slippery the on the stage load of suddenly disappear causable of ex- hurtle and load ofthe period vari
5、ety cause of the sport gravamen be steady, all is processed the surface quality ofpiece the influence, severity hour will cause the knife break.Request according to tool machinefactory in Dalian, the author adopts power key to match diagram and the analytical method establishment of the appearance s
6、pace to combine 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 system.Pass a calculator numeral to imitate really and study.Analytical slippery the pedestal produce ago hurtle
7、 and exercise not steady reason and main impact factor, in order to improvement slippery the dynamic state characteristic of pedestal.Two, dynamic state mathematics modelThe liquid which combines tool machine to slip a pedestal presses to drive system a from adjustto carry on the back to press to ad
8、just soon the work principle diagram of system,such as diagram I, to show.That system is the work circulation which uses to complete 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 hyd
9、raulic-pneumatic dint under thefunction which over flows valve look like ground to keep Heng settle, the oils liquid flows through to change toward the valve and adjust soon valve juniors into the oil urn of have no a pole chamber, push slippery the set be left shift;In the meantime, oil urn the pre
10、ssure 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 valve.In this process, two one-way valves with overflowed to flow valve and always dont change original work appearance.Object that system so of
11、 complications 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 important12.Know from the theories the analysis with experiment the resear
12、ch: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 moment is slippery pedestal sport spee
13、d of the variety be pimping2.For openning widely and going deep into dynamic state characteristic of study the system, make research work can on the microcomputer availably carry on, this text to original model2 do further simplification, on thesupposition that adjust soon the valve outputs in the w
14、hole transition process of system Hengsettle of discharge, treat it as to flow a source.So, 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 connectors roads etc. to constitute from the Dia
