Secure Pin Generator dialog box - Calculation Tab

This tab extends the Design tab. You can calculate generator data based on selections in the Design tab.

Access:

Ribbon: Design tab Fasten panel Secure Pin and click the Calculation tab.

Note: The Calculate command is available only if a pin is selected.

Type of Strength Calculation

Specifies the calculation method you select from a list. It determines which parameters are input parameters and which parameters are to be calculated. Note: The selection list is enabled only when a pin is selected.
Pin Design	Designs optimum secure pin dimensions for the indicated load, dimensions and joint properties.
Check Calculation	Performs a strength check for the specified load, dimensions, and joint properties.

Loads

Use Force F to enter Loading.

Dimensions

Pin Diameter	Choose a diameter of the pin.
Pin Length	Choose a length of the pin.
Bottom Board Thickness	Enter the bottom board thickness. You can enter the diameter or measure the diameter from ProdName using the options displayed when you click the arrow next to the edit field.
Top Board Thickness	Enter the top board thickness. If the sum of the bottom board and top board is not equal to the working pin length, the unequal widths turn red. This also indicates that the strength check of the pin is not satisfactory. Based on this dimension the appropriate secure pin is selected, you can enter the diameter or measure the diameter from ProdName using the options displayed when you click the arrow next to edit field.
Note: The values in the edit field that are not satisfactory turn red when you click Calculate.

Joint Properties

Service Factor	Represents a Type of Loading and type of Mounting. The allowed material value is lowered according to the selected type. Click next to edit field to open the Service Factor dialog box where you can select the Service Factor value.
Desired Safety	Taking into an account the accuracy and validity of input information, importance of the coupling, quality of production and accuracy of the calculation, it is chosen in a range from 1.5 to 10.

Pin Material

Warning: Determines empirically the strength parameters of material and reflects minimum values applicable for a group of materials. Although these values are close to the values obtained using measurement of particular materials, we recommend that you use parameters of material appropriate for the material sheet or specifications of the producer for final calculations.
Material	Specifies material values you enter or material you select from the Material Database. If a material is selected from the Material Database, values are inserted automatically into the following 3 edit fields, and the edit fields are locked. To unlock a field, clear the box.
Allowable Shear Stress	Specifies the allowable pin shear stress used in the calculation. The pin is checked for shear during the strength check.

Bottom Board Material

Material	Specifies material values you enter or material you select from the Material Database. If a material is selected from the Material Database, values are inserted automatically into the following three edit fields, and the edit fields are locked. To unlock a field, clear the check box.
Allowable Pressure	Enters the allowable pressure of the bottom board material with the least quality in the Joint Properties group. The bottom board is checked for pressure during the strength check.

Top Board Material

Material	Specifies material values you enter or material you select from the Material Database. If a material is selected from the Material Database, values are inserted automatically into the following 3 edit fields, and the edit fields are locked. To unlock a field, clear the check box.
Allowable Pressure	Enters the allowable pressure of the top board material with the least quality in the Joint Properties group. The top board is checked for pressure during the strength check.

Results

To display the Results area on the right side of the Calculation tab, double-click the double line on the right or click the chevron.

The area displays the calculated values and the secure pin strength check. Values are calculated when you click Calculate.

The units of the results values can be changed. Double-click the specified value you want to change.

Summary of Messages

Displays the reports about calculation. Opens the Summary of Messages area at the bottom of the Calculation and Design tabs, double-click the double line at the bottom of tabs or click the chevron at the bottom of the tabs.
