The two states of the metal hose when working under the elastic element

One is that the metal hose works under a certain load and displacement, and keeps the load and displacement constant or rarely changes, which is called static work;

Another use case is that the load and displacement of the metal hose alternately change periodically from time to time. The component is in a cyclic working state. Due to different working conditions, the modes of component damage or failure are also different. The elastic sensitive components of the instrument work within the elastic range, basically in a static working state, and have a long service life. The high-pressure hose generally reaches tens of thousands to hundreds of thousands of times. The bellows components used in engineering sometimes work in the elasto-plastic range or alternating stress state, and the life span is only hundreds of times. The allowable working life must be given when the component is working in cycles, and the number of cycles, time and frequency must be specified for large-diameter tubes. The rated life of the elastic component is the expected service life determined during the design of the component, and it is required that the component is not allowed to show fatigue, damage or failure during this period
