The service life of bellows is the shortest working period or cycle times to ensure normal operation when used under working conditions. The elastic sealing system composed of bellows often works under the conditions of variable load and large displacement with more cycles, so it is of great significance to determine the service life of bellows. Due to the different functions of bellows, the requirements for their service life are also
