Pin and Lug.xls
Purpose of calculation: Calculate the proof and ultimate strength of obliquely loaded lugs.
This calculation has been extended to also consider fatugue strength.
Calculation Reference: Traditional UK railway method.
Calculation Validation: This calculation requires validation.
1) It is normal to choose a pin size 6mm larger than required to allow for off centre drilling etc.
2) You may want to consider the use of a replaceable bush to increase the wear life of the lug.
3)You may also have to consider fatigue life.
