1. Definition of Ring Stiffness Testing Machine
Ring stiffness testing machine is a device specially used to test the deformation ability and stiffness of ring or tubular materials under stress conditions. It measures the material's resistance to deformation by applying radial or axial loads to evaluate its mechanical properties. This kind of equipment is widely used in the quality control and research and development of plastic pipes, rubber products, metal pipes and other materials.
2. Working principle of ring stiffness testing machine
The working principle of the ring stiffness testing machine is based on the basic principles of material mechanics. During testing, the sample is placed in the fixture of the testing machine and a uniform load is applied hydraulically or mechanically. The test machine records the relationship between load and deformation and calculates the ring stiffness value. The following are the main technical parameters of the ring stiffness testing machine:
| Parameter name | Typical value range | unit |
|---|---|---|
| Maximum load | 10-100 | kN |
| Test accuracy | ±0.5%-±1% | FS |
| Deformation measurement range | 0-50 | mm |
| Test speed | 1-500 | mm/min |
| Applicable sample diameter | 50-2000 | mm |
