In conjunction with Fig. 1～Fig. 3:
The adjustable buffer device of a kind of hopkinson test rod member of the utility model, comprises door 1, ring support 2, rubber bar 3, rear block seat 4, base 6; Ring support 2 is connected with base 6, and ring support 2 is enclosed within the interlude of rubber bar 3, and one end cover of rubber bar 3 has door 1, and the other end contacts with the rear block seat 4 being connected on base 6, gapped between door 1 and ring support 2.
Between ring support 2 and base 6, be connected by reinforcement.Reinforcement connects with base 6 by coupling nut 5.Coupling nut 5 is symmetrical about base axis.
Ring support 2 is annulus.
Its principle of work is: this device is by rubber buffer rod 3 impact-absorbing complementary energy, and fender pile 3 is arranged in ring support 2.Door 1 is enclosed within rubber bar 3 head positions, reduces impact pressure, avoids in impact process rubber bar 3 load that is directly hit to damage.Between door 1 and ring support 2, there is interval, the reserved required space of deformation occurs while absorbing buffering complementary energy for rubber bar.When buffering complementary energy is larger, rear block seat 4 blocks rubber bar and reaches stable object.
Embodiment 1:
The adjustable buffer device of hopkinson test rod member, comprises door 1, ring support 2, rubber bar 3, rear block seat 4, base 6; Ring support 2 is annulus, and itself and base 6 welding are connected, and ring support 2 is enclosed within the interlude of rubber bar 3, and one end cover of rubber bar 3 has door 1, and the other end contacts with the rear block seat 4 that welding is connected on base 6, gapped between door 1 and ring support 2.
Embodiment 2:
An adjustable buffer device for hopkinson test rod member, comprises door 1, ring support 2, rubber bar 3, rear block seat 4, base 6; Ring support 2 is hollow out ring support, between itself and base 6, is connected by reinforcement, and reinforcement connects with base 6 by coupling nut 5.Coupling nut 5 is symmetrical about base axis, ring support 2 is enclosed within the interlude of rubber bar 3, rubber buffer rod 3 and ring support 2 interference fit, one end cover of rubber bar 3 has door 1, the other end contacts with the rear block seat 4 being connected on base 6, gapped between door 1 and ring support 2, wherein, rear block seat 4 is connected by bolt with base 6.
Embodiment 3:
