Abstract
The invention relates to a method for testing oblique compression performance of a rubber fender. The method includes that an oblique platform with the oblique angle of theta is added on a flat press, and fixedly connected with the top of the rubber fender through bolts or other fastening members; the flat press applies a vertical pressing force on the oblique platform, then a pressing force in the angle theta with the vertical direction is applied on the rubber fender, and compression deformation amount and counterforce of the rubber fender are manually recorded or automatically recorded by equipment. The method has the advantages that during a vertical compression test of the fender, the oblique platform is additionally arranged on the rubber fender, so that when the oblique platform receives vertically-downward pressure, the rubber fender receives pressure in the angle theta with the vertical direction. By the method, stress conditions of the rubber fender when a ship berths with an angle in reality are simulated, so that performance of the rubber fender can be tested more comprehensively.
Description
Technical field
The present invention relates to rubber fender measuring technology, relate in particular to a kind of method of testing of rubber fender inclination compression performance.
Background technology
At present, according to rubber fender industry standard, after rubber fender sulfuration, the check of its quality is normally carried out to physical and mechanical properties test and Mechanics Performance Testing to rubber fender, main Mechanics Performance Testing is exactly vertical compression test, its testing apparatus is Flat pressure machine, by Flat pressure machine, rubber fender is applied to a vertical pressure, rubber fender is compressed to former high by 50%, 52.5% or 70%, calculate compression counter-force and absorb energy, by these two indexs, characterizing the mechanical property of rubber fender.But, this method of testing has only been considered the vertical compression of rubber fender, and during actual alongside, boats and ships always have certain angle and wharf anchors: boats and ships are in alongside, the pressure direction that rubber fender is subject to also not exclusively overlaps with the vertical center line of rubber fender, but having certain angle theta, θ angle is greater than 0 °, is less than or equal to 15 °.Therefore, for the method, also need to continue to upgrade.
Summary of the invention
For above defect, the invention provides a kind of method of testing of rubber fender inclination compression performance, when test, rubber fender is subject to the pressure in vertical direction with θ angle, thereby can more fully to rubber fender, carry out performance test and quality inspection.
For achieving the above object, the present invention is by the following technical solutions:
A method of testing for rubber fender inclination compression performance, step is:
(1) on Flat pressure machine, increase the sloping platform that a pitch angle is θ, θ angle is greater than 0 °, is less than or equal to 15 °;
(2) set sloping platform is fixedly connected with rubber fender top by bolt or other securing member, and this rubber fender bottom is fixedly connected with Flat pressure machine lower platform by bolt or other securing member;
(3) Flat pressure machine applies a vertical pressure to sloping platform, rubber fender is subject to the pressure in vertical direction with θ angle, the top of sloping platform and rubber fender is in the process moving downward, also there is a horizontal movement, adopt manual record or equipment automatically to record compress variation and the counter-force of rubber fender simultaneously;
(4) calculate the compression counter-force of rubber fender inclination compression verification and absorb energy, adopting these two parameters as the characteristic index of rubber fender inclination compression performance test.
The beneficial effect of rubber fender inclination compression performance method of testing of the present invention is: when carrying out the vertical compression test of fender, on rubber fender, set up a sloping platform, when sloping platform is subject to pressure straight down, rubber fender is subject to the pressure in vertical direction with θ angle, this method of testing has been simulated in reality, during the angled alongside of boats and ships, the stressing conditions of rubber fender, can more fully test out the performance of rubber fender; This method of testing is to the supplementing of the vertical compression verification of rubber fender, and is also perfect to rubber fender quality test; Can be widely used in cydariform rubber fender, cone rubber guard rail, arch shaped rubber fender etc.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the sloping platform schematic diagram of compression performance proving installation of tilting described in the embodiment of the present invention;
Fig. 2 is rubber fender inclination compression performance proving installation schematic diagram described in the embodiment of the present invention;
Fig. 3 is the inclination compressive state schematic diagram of proving installation described in the embodiment of the present invention.
Embodiment
As Figure 1-3, the method for testing of the rubber fender inclination compression performance described in the embodiment of the present invention, key step is:
(1) sloping platform is set: between rubber fender upper surface and pressing machine upper mounting plate, set up the sloping platform that a pitch angle is θ;
(2) set to be measured: set sloping platform is fixedly connected with rubber fender top by bolt or other securing member, this rubber fender bottom is fixedly connected with pressing machine lower platform by bolt or other securing member;
(3) test: pressing machine applies a pressure straight down to sloping platform, rubber fender is subject to the pressure in vertical direction with θ angle, the top of sloping platform and rubber fender is in the process moving downward, also there is a horizontal movement, adopt manual record or equipment automatically to record compress variation and the counter-force of rubber fender simultaneously;
(4) computational analysis: calculate the compression counter-force of rubber fender inclination compression verification and absorb energy, adopting these two parameters as the characteristic index of rubber fender inclination compression performance test.
Above embodiment is more preferably embodiment a kind of of the present invention, the common variation that those skilled in the art carry out within the scope of the technical program and replace and should be included in protection scope of the present invention.
