| Outline of Final Research Achievements |
A pneumatic actuating system has many advantages, including great power, small weight, safe use, and low cost. Air control devices are needed to control pneumatic actuators. However, the control devices that provide high controllability, such as proportional valves, are heavy and large scale; therefore, a smaller and lighter control valve is desirable. We previously proposed a valve mechanism using particle excitation by a piezoelectric (PZT) vibrator that boasts the advantages of small size, small weight, and continuous airflow control. In this report, we designed prototype using bolt-clamped Langevin-type transducer (BLT). And the parameters are optimised that orifice position, particle condition, and orifice size for proportional, stable flow condition.
