Model and Experimental Characteristics of a Pneumatic Linear Peristaltic Actuator
Pneumatic linear peristaltic actuators present several potential advantages over conventional ones such as low cost, virtually unlimited stroke, and an easy implementation of curved motion profiles. However, the body of this type of actuators also suffers from high mechanical stress, leading to a de...

| description | Pneumatic linear peristaltic actuators present several potential advantages over conventional ones such as low cost, virtually unlimited stroke, and an easy implementation of curved motion profiles. However, the body of this type of actuators also suffers from high mechanical stress, leading to a decrease in the hose wall thickness, which leads to increased leakages between chambers. One way to potentially minimize this problem is to impose the force instead of the displacement between rollers. This paper describes the model and experimental characteristics of a new prototype of a linear pneumatic peristaltic actuator where either the force or the displacement between rollers can be imposed. Namely, experimental friction characteristics and the leakage between chambers are determined in the configuration where the force between rollers is imposed. Lastly, a third-order linear model is experimentally identified. Therefore, this study establishes the basis for future research focused on the service life and leakage obtained whenever the force between rollers is imposed. |
