The engineering rubber compression shear testing machine is a specialized equipment used to test the mechanical properties of engineering rubber products such as bridge rubber bearings and high-speed rail rubber gaskets. It is widely used in quality inspection and scientific research fields in industries such as highways, railways, and construction.
1. The engineering rubber compression shear testing machine is mainly used for the following tests:
Axial compression test: Determine the compressive modulus of elasticity, compressive ultimate strength, etc. of rubber bearings.
Horizontal shear test: Evaluate the shear performance of rubber bearings under lateral force.
Corner test: Test the rotational ability of rubber bearings under stress.
Friction coefficient measurement (supported by some models): suitable for friction performance testing of spherical bearings and bowl bearings.
2. Equipment structure and composition：
Host frame: Usually adopts a four column or four screw structure to ensure high rigidity and stability.
Vertical loading: using hydraulic cylinders (bottom or top mounted), equipped with high-precision pressure sensors.
Lateral shearing system: composed of a horizontal oil cylinder, a shearing tension plate, and a reaction frame, it can move along the track.
Measurement and control system: computer-controlled, automatically collects data and generates reports. Can draw force displacement curves and calculate parameters such as elastic modulus and shear modulus.
3. Typical application areas：
Highway/railway bridges: testing the mechanical properties of plate rubber bearings and bowl bearings.
Building Seismic Reduction: Evaluating the Durability of Seismic Isolation Rubber Bearings.
Research institution: Study the mechanical behavior of new rubber materials.
