The content of the invention
Organizational project is a kind of bionical science, if external structure goes out tissue, structure and function that acquisition matches with it, then the mechanical condition of external loading just needs consistent with internal real force environment.Suitable mechanical environment is the necessary condition of Investigating Cartilage power biology.In order to meet the demand of cartilage tissue engineeredization culture, a kind of fatigue tester is have developed.
The technical solution adopted for the present invention to solve the technical problems is：
Provided with motor at lower formula fatigue tester is mainly made up of frame, incubator, flesh bone clamping device, pulling force sensor, incubator, casing etc., completes to load the stretching of flesh bone tissue with contraction；Described frame includes two support posts, rectangular slab, screwed adjusting rod and places the casing of voice coil motor；Screwed adjusting rod is fixed with described movable plate, disk is driven by operation handle so that adjusting rod can be with up and down, so as to reach the purpose of upper and lower two holder contacts and fixed test specimen；Described movable plate and the junction of column, are provided with the retainer plate of the constraint free degree, reduce the issuable vibration effect of drawing process central post；It is described to be mounted with that the pulling force sensor of pulling force size is surveyed between adjusting rod and upper fixture, analyze external flesh bone tissue engineer incubation for experimental simulation and real stress foundation is provided；Described casing is located at whole device bottom, is mainly constituted including voice coil motor, bolt, motor supporting plate, work top and base plate etc.；Described support post and column are connected, it is ensured that column is stablized vertically；Described voice coil motor is positioned on motor supporting plate, and supporting plate is fixed by screws on work top, voice coil motor is fixed between supporting plate and work top；Described fixture is made up of four parts, left fixture, right fixture, adjusting rod and rocking bar；Described left fixture is connected together with right fixture by adjusting rod, and when rocking bar is gone to, the fixture on the left side is motionless, and the fixture on the right is moved with the threads turn of adjusting rod so that crack increase or reduction between left fixture and right fixture.
Preferably, described movable plate and the junction of column, are provided with the retainer plate of the constraint free degree, the issuable vibration effect of drawing process central post is reduced.
Preferably, described casing is located at whole device bottom, mainly constituted including voice coil motor, bolt, motor supporting plate, work top and base plate etc..
Preferably, described motor is linear electric motors, electric energy can be directly changed into the mechanical energy of linear motion.
Preferably, the contact surface design of described fixture uses rough lines, it is to increase friction when test specimen is clamped work.
