Tooth high-cycle fatigue simulation test device and test method

Abstract

The invention discloses a tooth high-cycle fatigue simulation test device and test method. The device is characterized in that a first connecting rod, a second connecting rod and a driving connecting rod are hinged to the upper end face of a fixing plate, one end of the third connecting rod is hinged with one end of the first connecting rod, the other end of the third connecting rod is hinged with one end of the driving connecting rod, one end of the fourth connecting rod is hinged with one end of the second connecting rod, the other end of the fourth connecting rod is hinged with the other end of the driving connecting rod, a first clamping plate and a second clamping plate are fixedly connected with the other ends of the first connecting rod and the second connecting rod respectively, the opposite surfaces of the first clamping plate and the second clamping plate are respectively connected with a first tooth model and a second tooth model, when the driving connecting rod rotates and swings around the center line perpendicular to the fixing plate in a reciprocating mode, the third connecting rod and the fourth connecting rod can be driven to drive the first connecting rod and the second connecting rod to swing in a reciprocating mode, and when the first connecting rod and the second connecting rod swing in a reciprocating mode, the first clamping plate and the second clamping plate get close to each other or get away from each other. The device can be used for carrying out a simulation experiment on the wear resistance of teeth.

Description

technical field [0001] The invention relates to the technical field of tooth wear, in particular to a tooth high-cycle fatigue simulation test device and test method. Background technique [0002] Chewing is an essential physiological activity of human beings. Human beings meet the needs of human survival through chewing of maxillary teeth and mandibular teeth. Teeth must be worn to varying degrees during the chewing process. [0003] The amount of tooth wear is small in a short period of time, and there is currently no equipment for simulating the amount of tooth wear. Therefore, a high-cycle fatigue simulation test device for teeth is urgently needed to obtain the wear of the teeth. Contents of the invention [0004] Aiming at the technical problems existing in the prior art, the present invention provides a tooth high-cycle fatigue simulation test device and test method, which can carry out a simulation experiment on the wear resistance of the tooth, so that the wear co...

AI Technical Summary

Problems solved by technology

[0003] The amount of tooth wear is very small in a short period of time. At present, there is no equipment for simulating the wear of teeth. Therefore, there is an urgent need for a high-cycle fatigue simulation test device for teeth, so as to obtain the wear and tear of teeth.
