| in the palette | on the schematic |
The block is designed to simulate a linear translatory spring with a variable spring constant.
The deformation (extension) of the spring s in m is determined by the formula:
where:
- s0 – initial spring extension, m
- sC and sR – positions of bodies at ports "C" and "R", respectively, m
The spring elastic force is determined by the formula:
where:
- FC and FR – forces applied to ports "C" and "R", respectively, N
- K – defined spring constant, N/m
- Kmin – minimum spring constant, N/m

Properties
| Name | Parameter | Description | By default | Data type |
|---|---|---|---|---|
| Minimum spring constant, N/m | Kmin | Minimum spring constant | 1 | Вещественное |
| Initial extension (Sr - Sc), m | S0 | The initial extension of the spring at the zero positions of the bodies on the ports of the block. A negative value sets the pre-compression | 0 | Вещественное |
Parameters
| Name | Parameter | Description | Data type |
|---|---|---|---|
| Spring deformation, m | S | Extension value. Negative values mean compression | Вещественное |
| Elastic force, N | F | Force transmitted to port "R" | Вещественное |
