Type of Strength Calculation
|
Select the calculation method. It determines which parameters are input parameters and which parameters to calculate. Note: The selection list is enabled only when pin is selected.

|
Clevis Pin Design |
Designs the optimum clevis pin dimensions for the specified load, dimensions and joint properties. |
|
Check Calculation |
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. |
|
Clevis Width |
Choose the width of the clevis. Based on this dimension the appropriate clevis pin is selected, you can manually type the diameter or measure the diameter from Autodesk Inventor using the options displayed after clicking the arrow next to edit field. |
|
Rod Width |
Choose the width of the rod. Enter the width of the clevis rod according to the part dimensions. If the sum of the clevis and rod widths 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 rod is selected, you can manually type the diameter or measure the diameter from Autodesk Inventor using the options displayed after clicking the arrow next to edit field. |
|
Note: The values in the edit field that are not satisfactory turn red when the Calculate command is pressed.

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 |
|
Desired Safety |
With regards to accuracy and credibility 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. |
next to edit field to open the Service Factor dialog box where you can select the Service Factor value. Pin Material
|
Warning: Strength parameters of material are determined empirically and reflect minimum values applicable for a group of materials. Although these values are close to the values obtained using measurement of particular materials, we recommend in cases of final calculations to use parameters of material according to the material sheet or specifications of the producer. |
|
|
Material |
You can specify your own material values or select a material from Material Database. If a material is selected from the Material Database, its values are inserted automatically into the following 3 edit fields, and the edit fields are locked. To unlock the field, clear the check box. |
|
Allowable Bending Stress |
Specifies allowable pin bending stress used in calculation. The clevis pin is checked for bending during the strength check. |
|
Allowable Shear Stress |
Specifies allowable pin shear stress used in calculation. The clevis is checked for shear during the strength check. |
