Stiffness calculations of components.
| Components | Length (mm) | Sectional Area (mm2) | Elastic Modulus (MPa) | Stiffness (kN/mm) | |
|---|---|---|---|---|---|
| Symbol | Value | ||||
| Heated column | 1000 | 3848 | 210,000 | 808.17 | |
| Thread column | 800 | 3318 | 210,000 | 871.06 | |
| Upper thread rod | 300 | 1963 | 210,000 | 1374.45 | |
| Specimen | 300 | 10,000 | 30,000 | 1000.00 | |
| Oil cylinder * | 300 | 6362 | 2000 | 42.41 | |
* In the stiffness calculation, the oil cylinder is simplified as a compressed cylinder with the elastic modulus transformed from the bulk modulus of hydraulic oil.
