Description

Shear stress bringing device in a kind of physical analogy

Technical field

The utility model is related to structural physical simulation field, shear stress bringing device in especially a kind of physical analogy.

Background technology

In structural physical simulation field, the construction feature under the conditions of simulation shear stress is generally required.In different areas, no With earth history period, the size of shear stress is often different in physical model；How accurate, reasonable, quick simulating boundary Structure development feature under shear stress affact is the big difficult point that structural physical simulation faces.

Utility model content

The utility model aims to solve the problem that the above problem, provides shear stress bringing device in a kind of physical analogy, it overcomes Traditional method cannot be under accurate, reasonable, quick simulating boundary shear stress affact structure development feature the problem of, adopt Technical solution is as follows：

Shear stress bringing device in a kind of physical analogy applies plate, elastic restraint pipe, cunning including physical model, shear stress Moving axis and elastic piece；The elastic restraint pipe is connected by sliding axle with elastic piece；The elastic piece is fixed on physics On model；The length of the elastic piece is more than the length of elastic piece；The surface that the shear stress applies plate is coarse.

The utility model has the following advantages that：Design is reasonable, can accurate, reasonable, quick simulating boundary shear stress affact Under structure development feature, it is workable, it is easy to carry.

Description of the drawings

Attached drawing is the stereoscopic schematic diagram of the utility model；

In attached drawing, 1. physical models, 2. shear stress apply plate, 3. elastic restraint pipes, 4. sliding axles, 5. elastic pieces.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

Shown in attached drawing, shear stress bringing device in a kind of physical analogy applies plate 2, bullet including physical model 1, shear stress Property confinement tube 3, sliding axle 4 and elastic piece 5；The elastic restraint pipe 3 is connected by sliding axle 4 with elastic piece 5；Described Elastic piece 5 is fixed on physical model 1；The length of the elastic piece 5 is more than the length of elastic piece 5；The shear stress is applied The surface of splice 2 is coarse.

When in use, by the relative position of regulation elasticity confinement tube 3, rational shear stress scope is controlled；By shear stress Apply plate 2 to slide on physical model 1, construction feature variation of the analog physical model under shear stress affact.

The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation Example, all scopes that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
