Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
Six degree of freedom boundary condition simulation device is as the core ingredient of six degree of freedom edge load experimental system for simulating, and whether its structural design rationally becomes the key factor that can this experimental system successful.
The utility model provides a kind of six degree of freedom edge load experimental system for simulating.Comprise control system (control system is a prior art, does not repeat them here), hydraulic power supply (be prior art, do not repeat them here) and six degree of freedom boundary condition simulation device, six degree of freedom boundary condition simulation device is the core of system for this reason.
The six-freedom degree that described six degree of freedom promptly moves and rotates around x, y, three axles of z respectively along x, y, three axles of z respectively.Referring to figs. 1 to Fig. 4, six degree of freedom boundary condition simulation device comprises 6 actuator, two right side actuator 30 wherein, three vertical actuator 20, a rear side actuator 40,6 actuator coordinated movements of various economic factors load, support tip motion platform 60, terminal motion platform 60 can realize tensile, compressive, bending, turn round, cut or multi-form load such as its combination loads, on the six-freedom degree direction, can realize the control of displacement and power, also can add other actuator and directly affact on the test specimen to realize more complicated loading.
With reference to figure 5, described actuator comprises ball pivot support 11, ball pivot support 13 and servo hydraulic cylinder 12; Described ball pivot support 11 and ball pivot are servo hydraulic cylinder 12 between supporting 13, and ball pivot supports and can rotate in any direction.6 actuator support 13 by ball pivot support 11 and ball pivot and are fixed together with frame 10 in different directions respectively, and the other end is fixed on the terminal motion platform 60.Hydraulic power supply provides hydraulic power for servo hydraulic cylinder 12 under control system control.
Gusset 50 is set on the frame 10, and gusset 50 works to strengthen the frame load-bearing capacity, improves the bulk strength of boundary condition simulation device.
Terminal motion flat 60: when each actuator coordinated movement of various economic factors loads, will produce the load of size, direction variation endways on the motion platform 60.Because an end and the terminal motion platform 60 of detected member link together, the load that the boundary condition simulation device produces can be applied on the border of detected member by motion platform.
The experiment using method of six degree of freedom edge load experimental system for simulating:
With reference to figure 6, when six degree of freedom edge load experimental system for simulating experimentizes to detected member, the one side of six degree of freedom boundary condition simulation device machine 10 is fixed together with shear wall 70, to guarantee the stability of boundary condition simulation device in experimentation.One end of detection piece 2 is connected with terminal motion platform 60, and the other end and Strong floor 3 are fixed together.When 6 actuator motions load, the load that produces is applied on the detected member 2 by terminal motion platform 60, the boundary of detected member 2 produce simultaneously along three axles move and around the rotation of three axles, respective change will take place along with the variation of actuator load in the load that detected member 2 borders are subjected to, realized the harmony loading of six degree of freedom, real simulation material or structure load at boundary.Thereby obtain truer, mechanical property experimental data accurately, for the researchist provides favourable experimental data.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
