The invention discloses a static loading test device for a prosthetic ankle and foot structure. The static loading test device comprises a linear motor, a lead screw, an upper limit switch, a lower limit switch, a pressure sensor, a loading portion, a clamp horizontal adjusting knob and a clamp vertical angle adjusting knob; the output end of the linear motor is connected with the lead screw; thelead screw is in engaged connection with the loading portion through screw threads; the upper portion of the loading portion is connected with the pressure sensor; the prosthetic ankle and foot structure is arranged below the loading portion; the prosthetic ankle and foot structure is installed on a clamp; the clamp is provided with the clamp horizontal adjusting knob and the clamp vertical angleadjusting knob; the upper portion and lower portion of one side of the lead screw are respectively provided with the upper limit switch and the lower limit switch; and a control box is below the clamp. With the static loading test device for the artificial ankle and foot structure of the invention adopted, the static structural performance and static damage performance of the prosthetic ankle andfoot structure can be detected. The static loading test device for the prosthetic ankle and foot structure has the advantages of simple structure, convenient operation, high safety, high reliability and good experimental analysis effect.
Description
technical field [0001] The invention relates to the technical field of rehabilitation appliances, in particular to an ankle-foot static loading test device. Background technique [0002] Static test is relative to dynamic test, the load on the sample is small, the deformation speed is slow enough or the test time is short. Such as tensile test, bending test, hardness test, etc. Static tests can also be called routine tests. Regardless of the viscoelastic behavior of the material or the phase difference between stress and strain, the classical theory of material mechanics is generally used to deal with the problem. [0003] Ankle foot (prosthetic foot) static structural performance test. Loading process: 1. According to figure 1 Install the test sample on the test equipment, and increase the test force F smoothly at a certain rate 1 , the loading direction is Θ fu1 , to make it reach the verification test force F of the corresponding load level 1sp , according to the s...
