During the design and development process Mechanical fatigue testing and component life
prediction are critical factors for safe and reliable behavior of component. Before being used in
real-world applications, parts, components, and prototypes must be fatigue tested to determine how
long they will last. A machine setup capable to generate desired load is required for the prediction
of component life under continuous loading or under fatigue. The current work displays a fatigue
testing system for rubber components that is powered by a pneumatic mechanism. Continuous
loading is applied to a rubber component for a predetermined number of cycles, and the resulting
load and distance are calculated. The entire system is further separated into two sections: electrical
and mechanical.
Entire setup comprises of base structure, air compressor, pneumatic cylinder actuator, proportional
servo valve, buck module, load cell transducer, laser distance sensor, signal generator, DC power
supply, load cell amplifier and Data Acquisition Card. Obtained parameters are transferred into an
integrated computer system and Data Analysis is carried out using Lab VIEW.
