Embodiment Construction

[0022] The present invention is further described below in conjunction with accompanying drawing:

[0023] see figure 1 , a rubber material elastic modulus measuring device, comprising a base 8, a dial indicator 4 and a flat plate 3; both ends of the lower surface of the flat plate are fixedly provided with a dial indicator 4; the test piece is arranged on the base 8, and the flat plate 3 is placed on On the upper surface of the test piece, the lower end of the dial gauge 4 is against the base 8 .

[0024] The base 8 is provided with a test piece placement platform 7, and the test piece is placed on the test piece placement platform 7. Two bosses 6 with the same height are symmetrically arranged on the base 8 on both sides of the test piece placement platform 7. The lower end of the dial gauge 4 Arrest on the boss 6.

[0025] The plate 3 is provided with a through hole at the position where the dial gauge 4 is arranged, and the top of the dial gauge 4 passes through the thro...

Abstract

A device for measuring elasticity modulus of a rubber material comprises a base, dial indicators and a flat plate; the dial indicators are separately fixedly arranged at two ends of the lower surfaceof the flat plate; a test piece is arranged on the base; the flat plate is placed on the upper surface of the test piece; and the lower ends of the dial indicators are abutted to the base. The flat plate and the dial indicators can be fixed together quite well by nuts, and moreover, disassembling is facilitated; and pressure is applied by weights, because the weights are standard pieces, the applied pressure can be calculated quite rapidly, the stress of the rubber test piece can also be calculated quite rapidly, and the calculating efficiency is improved to a great extent.

Description

technical field [0001] The invention belongs to the technical field of elastic modulus measuring devices, in particular to a measuring device and a measuring method for elastic modulus of rubber materials. Background technique [0002] The elastic modulus of rubber is an index to measure the difficulty of elastic deformation of rubber materials. The larger the value of the elastic modulus of rubber, the greater the stress that makes the rubber material undergo a certain elastic deformation, that is, the greater the stiffness of the rubber material. Under the action of a certain stress, the elastic deformation is smaller. It can be seen that the elastic modulus of rubber is an index reflecting the ability of rubber materials to resist elastic deformation. [0003] Rubber is an engineering material that can be made into a variety of rubber products and is widely used. Its physical properties are extremely important to the performance of the products. Rubber has the ability to...
