Abstract:

Bellows is a thin-walled metal cylindrical with folds, as a pipeline connection and compensation device, it has the feature such as reliable and compact. Now Bellows is widely used in the produce of aerospace engines and the relative industries. In order to solve the load life test problem of bellows, the squeezing and twisting process after the long time loading is simulated by swinging and pressing it rapidly in a short time. Adopting NI Real-Time Hypervisor，a real-time monitor and test system is built by Windows operation system. According to the real twist data of bellows,the dynamic equation of swing platform for two cylinder is constructed, by the real-time and a high precsion control of the motion of two cylinders, the bellows which is full of liquid has been squeezed and twisted with a high frequency, and loading test of the mechanical properties, strength and lifetime for bellows is achieved in an automatic way.
