Deng, and the steel wire rope in civil engineering and steel strand wires.Sea cable is mainly responsible for seabed production equipment and provides electric energy, umbilical cables master
The correlation function such as electric power, signal transmission between water floating body to be provided and subsea equipment, flexible duct is mainly responsible between equipment
Oil-gas transportation.Steel wire rope is mainly used in crane as traction equipment, and steel strand wires are typically used as holdfast in earthwork engineering.
The common trait of said structure is that outer layer all has the spiral wound steel wire armouring promoting stretch resistance, and this form ensure that stretching
The compliance of structure is improved while ability.But, in particular cases, the work of the axially compressed load of spiral winding armor
The Buckling modes of two kinds of forms now it is susceptible to: radially flexing and lateral buckling with, steel wire.Radially camptodactyly armouring wire edge
Radially projecting, it is shaped like " birdcage ", therefore also referred to as " birdcage phenomenon "；Lateral buckling refers to that armouring wire is laterally sent out along periphery
Raw offset slide torsional deformation.Flexing currently for both forms is mainly entered by theoretical, numerical value and three kinds of methods of experiment
Row research.Compared to remaining two kinds of research method, the result that experimentation obtains has more actual directive significance.In order to enable comprehensively
The flexing failure mode of spiral wound steel wire is furtherd investigate by ground, it is necessary to bend a single and many spiral wound steel wire
Bent mechanism carries out experimentation, and this patent lost efficacy mainly for radial direction flexing and carries out the design of experimental provision.
Summary of the invention
According to technical problem set forth above, it is provided that the radial direction buckling experimentation dress of a kind of spiral wound steel wire
Put.Whether the steel wire rope in ocean engineering flexible pipe cable, or civil engineering, its version and physical dimension have substantially
Difference.Being mainly used in experimental subject in view of apparatus of the present invention is spiral wound steel wire, therefore, by steel wire winding internals

Steel wire radially buckling carries out the experimental provision studied.According to the studies above target, designed radial direction buckling experiment dress
Put and should include pressing driving means and ensureing that steel wire is not along the restraint device of cylindrical core central motion.In addition, tested
Journey needs to configure measurement equipment, such as foil gauge and pressure transducer etc. to extract steel wire deformation process relevant parameter and spiral steel
The counteracting force of silk.Radially flexing experiment flow is generally in accordance with following steps: sample, fix, pieces of cloth, load, measure and after locate
Reason mode expansion.Experiment to be formulated corresponding testing scheme before starting and choose spiral wire, then by spiral shell to be tested
Rotation fixation with steel wire is in the two ends of cylinder (effect is similar to cylindrical core), and draws the steel wire position line, is used for and steel wire after experiment
Position contrasts.Carry out the layout of foil gauge and pressure transducer according to requirement of experiment at test position, and be coupled with
Data acquisition equipment.Guarantee the errorless rear start-up loading equipment of aforesaid operations, Real-time Collection related data simultaneously.Finally, to gained
