| Abstract [eng] |
The standard of mountain bicycles defines the requirement of frame and fork assembly fatigue test by horizontal force. During the test the frame and fork assembly is deformed by cyclic loading. It causes the strains in elements assembly which are varying in time. Used testing machine with pneumatic muscles actuator allows to carry out test with different values of horizontal forces and different loading frequencies. The work presents experimental data of fork strain range, dependant on frame and fork assembly loading frequencies (0,1; 0,5; 1; 1,5; 2; 4; 6; 8; 10 Hz). The results allowed to do the conclusion that pneumatic muscles actuator is not applicable for frame and fork assembly loading. |
