Disc spring calculator
This is a basic tool and we encourage the user to verify calculations from first principles themselves.
1. Our naming convention uses deflection, compression and travel interchangeably (they all mean the same thing).
2. We use the lower case to refer to a value pertaining to a single disc spring, and an upper case to the value as it pertains to the stack. For example, (s) refers to the compression/travel of a single disc spring, whilst (S) that of the stack. Likewise, l0 is the overall height of a disc spring, whilst L0 is the overall length of the stack.
3. We use an apostrophe (') to reference a value derived from a reduced thickness, where t' is the reduced thickness. Where a reduced thickness disc spring is not relevant we just set the two values equal to each other, thus cone height h0 = h'0
