為特定應用擇最宜之浮升機制:定需求、以硬約束篩候選、以軟標準評倖存者,並於可復現之權衡研究矩陣中記其決定。
於評任何機制前定全需求之集:
## Requirements Summary
| Category | Requirement | Value | Priority |
|----------|------------|-------|----------|
| Payload mass | Range | [min - max] kg | Must have |
| Payload material | Magnetic class | [ferro/para/dia/non-magnetic] | Must have |
| Gap | Levitation height | [value] mm | Must have |
| Precision | Position accuracy | [value] um | Want |
| Temperature | Operating range | [min - max] C | Must have |
| Power | Budget | [value] W | Want |
| Cost | Unit cost target | [value] | Want |
| Environment | Cleanliness | [class or none] | Must have |
| Noise | Acoustic limit | [value] dB | Want |
| EMC | Field emission limit | [value or none] | Want |
預期: 需求表,每需求分為「Must have」(硬約束,過/敗)或「Want」(軟標準,以分標評)。至少定 5 需求。
失敗時: 若應用定義過泛不能設定量需求,訪利害關係人或行邊界分析:定各參數可接受之最寬範圍。無已定需求而行之導致權衡研究武斷或有偏。
列待評之浮升機制及其運行原理與基本限:
被動抗磁浮升:用所浮物(或抗磁穩定器)於永磁場中之抗磁磁化率。無需功率。限於小負載(毫克至克)且強抗磁材料(熱解石墨、鉍)。室溫運行。
主動電磁反饋:帶位置感測器與實時控制器之電磁鐵。處理自克至數百噸之負載(maglev 列車)。需連續功率與控制系統。適用於鐵磁與導電負載。
超導浮升:帶磁通釘扎之 II 型超導體提供被動、無功之浮升,具本徵穩定。需低溫冷卻(YBCO 77 K 需液氮,常規超導體需液氦)。負載限於超導體尺寸與臨界電流。極剛。
聲駐波:超聲換能器建壓力節點以陷小物。負載限於次波長物(於 40 kHz 空氣中典型 < 5 mm)。需連續驅動功率。不論磁或電性皆可。生可聞諧波與聲流。
聲相控陣:駐波浮升之擴,用多獨立控之換能器。可行三維操作與重定位。複雜與成本較高但靈活得多。
氣動(空氣軸承):加壓空氣之薄膜支物。用於精密臺、氣墊桌、氣墊船。需連續供氣。極低摩。精密軸承間距典型 5-25 微米,氣墊船更大。
氣動(Coanda/Bernoulli):空氣射流導向曲面建低壓區以懸物。簡便而廉。精度與剛度低。用於演示與某工業處理。
靜電(庫侖):帶電電極懸帶電或介電物。力極低(微至毫牛)但可於真空用。用於空間應用(引力波探測、慣性感測)與 MEMS。
靜電(離子陷阱):振蕩電場(Paul trap)或合靜磁場(Penning trap)限帶電粒子。用於單離子至奈米顆粒。主要為原子物理與質譜之實驗室技。
## Candidate Mechanisms
| # | Mechanism | Payload Range | Power | Temperature | Any Material? |
|---|-----------|--------------|-------|-------------|--------------|
| 1 | Passive diamagnetic | mg - g | None | Room temp | No (diamagnetic only) |
| 2 | Active EM feedback | g - 100+ t | Continuous | Room temp | No (ferro/conductive) |
| 3 | Superconducting | g - kg | Cryocooler | < 77 K | No (above SC) |
| 4 | Acoustic standing wave | ug - g | Continuous | Room temp | Yes |
| 5 | Acoustic phased array | ug - g | Continuous | Room temp | Yes |
| 6 | Air bearing | g - t | Air supply | Room temp | Yes |
| 7 | Coanda/Bernoulli | g - kg | Air supply | Room temp | Yes |
| 8 | Electrostatic Coulomb | ug - mg | Minimal | Any (vacuum ok) | No (charged/dielectric) |
| 9 | Ion trap | atoms - ug | RF power | Any (vacuum) | No (ions only) |
預期: 含所有物理上可行之機制之目錄,其基本特性已摘。至少 4 機制跨至少 2 不同物理原理。
失敗時: 若機制之基本限不定,查文獻或用相關分析技(analyze-magnetic-levitation、design-acoustic-levitation)以定之,然後進篩選。勿以猜度而篩。
汰任「Must have」之需求不過之機制:
## Screening Results
| # | Mechanism | Pass/Fail | Eliminating Constraint | Reason |
|---|-----------|-----------|----------------------|--------|
| 1 | Passive diamagnetic | [P/F] | [constraint or N/A] | [reason] |
| 2 | Active EM feedback | [P/F] | [constraint or N/A] | [reason] |
| ... | ... | ... | ... | ... |
預期: 縮減之候選機制清單,各已過所有硬約束。至少一機制過篩;理想 2-4 留供評分。
失敗時: 若無機制過所有硬約束,則需求相互矛盾。鬆最不關鍵之「Must have」需求(改為「Want」)並再篩。若需鬆多需求,應用或需合二機制之混合法(如磁主力配氣動穩定)。
以加權評分矩陣排倖存之機制:
## Scoring Matrix
| Criterion | Weight | Mech A | Mech B | Mech C |
|-----------|--------|--------|--------|--------|
| Cost | [w1] | [s1A] | [s1B] | [s1C] |
| Complexity | [w2] | [s2A] | [s2B] | [s2C] |
| Precision | [w3] | [s3A] | [s3B] | [s3C] |
| Power | [w4] | [s4A] | [s4B] | [s4C] |
| Scalability | [w5] | [s5A] | [s5B] | [s5C] |
| Controllability | [w6] | [s6A] | [s6B] | [s6C] |
| Maturity | [w7] | [s7A] | [s7B] | [s7C] |
| **Weighted Total** | | **[T_A]** | **[T_B]** | **[T_C]** |
| **Rank** | | [rank] | [rank] | [rank] |
預期: 完整評分矩陣,所有標準已加權且所有機制已評分。明排序呈現,首候選已識。靈敏度分析確排序穩健(或記其脆處)。
失敗時: 若二機制分相差 10% 內,紙上決定過近。建議原型化兩者並依實驗效能擇之,或識一可破平之辨別性測試。
