Description
Technical field
The invention belongs to mechanical field, refer in particular to a kind of simulating test device.
Background technology
Rubber-plastics material is widely used in all trades and professions because of its intrinsic excellent specific property, particularly the field such as track traffic, space flight and aviation.Plastic Rubber Products can be easy to make various singular configurations, meet the needs of particular surroundings and special construction, and can carry the load of any direction, in bearing load, there is the effects such as shock-absorbing, buffering, so above-mentioned characteristic also determines the detection of Plastic Rubber Products and test, also need special structure and special means.Experimental test was all to do unidirectional test and check for rubber-plastics material itself in the past, now because the complicacy of applied environment and structure, merely the one direction test and check of material has not been had to the meaning of representative, for the multidimensional of the concrete assembly structure of Plastic Rubber Products or product practical application operating mode, tested and just have more practical significance.
Summary of the invention
The invention provides the three-dimensional alternate load fatigue experimental device of a kind of rubber and plastic joint assembly, is unidirectional to solve existing experimental test and check, can not be applied to the problem of operating mode multidimensional test.
