Problems solved by technology

[0003] At present, there are relatively few test methods for testing the mechanical properties of the femur, and the existing test fixture can only be used to compress the femur in one direction, and it is impossible to explore the mechanical properties of the femur in multiple directions
On the other hand, the existing femur test fixture can only perform static compression tests to test the static mechanical properties of the femur, but cannot perform compression-compression fatigue tests to test the fatigue mechanical properties of the femur

Abstract

The invention discloses a femur static compression and compression-compression fatigue test method, relating to a femur test method. Start the fatigue testing machine, and assemble the test fixture between the two clamps. The test fixture has the characteristics of multiple degrees of freedom. The femur is completely placed in the test fixture, and the clamp moves upward under the control of the computer to apply preload to the femur. The static compression test is adjusted to the static compression test procedure, and the loading speed and loading termination conditions of the force are set. The compression-compression fatigue test is adjusted to the compression-compression fatigue test procedure, and the amplitude and vibration frequency of the lower chuck are set. At the same time, set the loading termination conditions of the fatigue testing machine, start the program, start the test, and record the test data, then unload the force of the fatigue testing machine, adjust the tilt angle of the femur and repeat the test. In this way, the femur can be tested from different directions, and the mechanical properties of the femur can be explored more comprehensively.

Description

technical field [0001] The invention relates to a femur test method, in particular to a femur static compression and compression-compression fatigue test method, belonging to the technical field of femoral mechanics tests. Background technique [0002] In recent years, the intersection of medicine and engineering has gradually become a hot issue of scientific research workers. For the field of solid mechanics, it is more closely related to medicine and biology. Biomechanics has become a hot topic in the field of biomechanics and solid mechanics. In the field of biomechanics, there are more and more studies on the femur. [0003] At present, there are relatively few test methods for testing the mechanical properties of the femur, and the existing test fixtures can only be used to compress the femur in one direction, and it is impossible to explore the multi-directional mechanical properties of the femur. On the other hand, the existing femur test fixture can only perform sta...
