This is my first post! I would like to ask you to teach me how to calculate the initial load of a compression spring. Currently, in the inspection of the process using compression springs at work, the presence or absence of the initial load is a problem for inspection accuracy, so in order to clarify, I would like to know the calculation method to obtain the initial load. I hope you can teach me. Thank you for your cooperation.
Thank you for writing to us, Miyamoto! There is no particular regulation regarding the initial load value of the compression coil springs. As for the range of use of coil springs, we recommend using them within 30 to 70% of the total amount of deflection where the spring constant is stable, so please refer to that!
