Specification Specifies a combination of force and geometrical restrictions: Load, Deflection / Load, Length / 2 Load, 2 Length / 2 Loads, Travel / Detailed. Select an appropriate combination based on the disposable input data. After selecting the specification, a spring picture with dimension buttons and a value table of restrictions appears. |
|
|
Absolute set Contains two options: Lengths and Forces. If the Force is of the absolute value, then the length is within the range from - to, and the other way around. |
|
|
Loads Select how you want to define loads - using moments or forces |
|
|
Restrictions table To insert a restriction into the table, click on the dimension button (for example: Da) in the spring picture to the right of the table. A new empty row appears in the table. To enter values into the cells, click on a cell. You can also enter geometrical values (length and diameter) using the measure button in the cell and then making selections in the graphic area. Use the buttons in the cells (< >, < =, = >, =) to add further restrictions to the spring. To activate a dynamically loaded spring use the Dynamic Loads check box. This option affects calculation of stresses. |
|
|
Settings Opens the Additional Settings dialog box. |
|
|
Back Lets you change the location and direction of the spring. |
|
|
Next Finds appropriate springs in the table according to restrictions and displays them in the result table along with important dimensions and calculation results. |
|
|
Finish Finds and inserts the appropriate springs in the table into your drawing. You can dynamically drag the springs in the drawing. |
|
|
Select All Lets you quickly select all springs in the result list. If you select more than one spring from the result list, dynamic dragging is activated when you press the Finish button so you can select more springs from the graphic area |

Results: Loads tab |
|
|
Spring dimensions: d-wire diameter x Da-outer diameter x L0-unloaded length. Depending on the selected standard, instead of outer diameter Da mean diameter Dm can be displayed. |
|
|
Force: F1- load in state 1, F2- load in state 2, Fn- maximum allowed load. |
|
|
Deflection s1- deflection in state 1, s2- deflection in state 2, sn- maximum allowed deflection. |
|
|
Length: Lengths of spring caused by corresponding forces (L1, L2, Ln). Number of displayed forces depends on selected specification. |
|
|
Results: Stresses tab |
|
|
Stress: Stress in spring calculated according to the forces. |
|
|
Allowed: Allowed stress in spring |
|
|
Safety: Safeties calculated as a ratio between stress and allowed stress in the spring |
|
|
Results: Other tab Displays information about the spring such as allowed number of stress cycles. |
