Experimental Verification of the Design Strategy of Pneumatic Components Based on Pneumatic Frequency Ratio

The existing selection and design methods for pneumatic systems and components have scale redundancy, resulting in high energy consumption. To address this issue, a pneumatic system and component selection optimization design method based on the pneumatic frequency ratio is proposed. The dynamic model of a typical pneumatic action system is established to lay the theoretical foundation for the subsequent energy-saving design methods. Combining the concept of natural frequency, the concept of pneumatic frequency ratio is proposed. Furthermore, from the perspective of resonance, the optimization design strategy of pneumatic components when the pneumatic frequency ratio is 1 is proposed. The energy-saving performance of the system selected by traditional methods and the system selected based on the pneumatic frequency ratio of 1 are experimentally verified. The experimental results show that this optimization design method can save energy up to 25.9%., providing a new basis for the selection and design of pneumatic systems considering energy efficiency optimization.
