Size a vacuum generator and suction cups from cup diameter, cup count, vacuum level, air-supply pressure, safety factor and target response time, with gripping force and required flow.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Flow-rate characteristics | Pneumatic components are characterised by sonic conductance C and critical pressure ratio b | ISO 6358:1989, Pneumatic fluid power - Determination of flow-rate characteristics |
| Critical pressure ratio | Choked flow occurs once the downstream-to-upstream pressure ratio drops below the critical value | ISO 6358:1989, Pneumatic fluid power - Determination of flow-rate characteristics |
| Conversion to standard conditions | Gas flow must be converted to standard reference atmosphere to be comparable | ISO 6358:1989, Pneumatic fluid power - Determination of flow-rate characteristics |
| Vacuum level versus suction flow | Suction flow falls as vacuum level rises; select against the curve at the working vacuum | ISO 6358:1989, Pneumatic fluid power - Determination of flow-rate characteristics |
根據吸盤直徑、數量、真空度與供氣壓力，計算吸附力、所需抽吸流量與響應時間，並結合負載給出吸盤選型與安全餘量校核。純前端執行，資料不上傳。
