Abstract:As a novel and flexible actuator, the water hydraulic artificial muscle (WHAM) has become at the forefront of bionic robot research. In order to explore the fatigue behavior of WHAM, the lifetime of WHAM was analyzed based on the crack propagation of neoprene rubber and the S‐N curve of aramid fiber. Meanwhile, WHAM's fatigue tests were carried out, and the fatigue life exceeded 56,000 cycles under the pressure of 2 MPa and the elastic load of 1030.7 N/mm. In addition, WHAM's fatigue failure is represented as … Show more
