analyze-tensegrity-systemAnalyze a tensegrity system by identifying compression struts and tension cables, classifying type (class 1/2, biological/architectural), computing prestress equilibrium, verifying stability via Maxwell's rigidity criterion, and mapping biological tensegrity (microtubules, actin, intermediate filaments). Use when evaluating tensegrity in architecture, robot…

析張拉系——孤壓元(柱)以續張網(索)穩。定力衡、預應衡、構穩、跨尺一致由分子骨架至建。
定每壓元(柱)與張元(索)、其連、界條以立全物述。
## System Characterization
| ID | Type | Length | Cross-section | Material | Stiffness |
|----|-------|----------|---------------|----------------|---------------|
| S1 | strut | [value] | [value] | [material] | E = [value] |
| C1 | cable | [value] | [value] | [material] | EA = [value] |
- **Nodes**: [count], [fixed vs. free]
- **Scale**: [molecular / cellular / architectural / robotic]
- **Boundary conditions**: [description]
得:諸壓張元之全錄附材性、關聯矩、足以設衡方之界條。
敗:元性未知(生系常)→用出版值:微管(E ~ 1.2 GPa,持久長 ~ 5 mm)、肌動(E ~ 2.6 GPa,持久長 ~ 17 um)、中纖(高非線、應變硬,初模 ~1 MPa 升至高應變 ~1 GPa)。連不清→簡至最簡拓捕本力路。
定系屬何張拉類及生或工。
## Tensegrity Classification
- **Class**: [1 (isolated struts) / 2 (strut-strut contact)]
- **Dimension**: [2D / 3D]
- **Topology**: [prism / octahedron / icosahedron / X-module / irregular]
- **Category**: [biological / architectural / robotic / artistic]
- **b** (members): [value], **j** (nodes): [value]
### Biological Tensegrity Mapping (if applicable)
| Cell Component | Tensegrity Role | Key Properties |
|-------------------------|-----------------------|---------------------------------------------|
| Microtubules | Compression struts | 25 nm OD, E~1.2 GPa, dynamic instability |
| Actin filaments | Tension cables | 7 nm, cortical network, actomyosin contract. |
| Intermediate filaments | Deep tension/prestress| 10 nm, strain-stiffening, nucleus-to-membrane|
| Extracellular matrix | External anchor | Collagen/fibronectin, integrin attachment |
| Focal adhesions | Ground nodes | Mechanosensitive, connect cytoskeleton to ECM |
| Nucleus | Internal compression | Lamina network forms sub-tensegrity |
得:明分(類、維、種)附生表完於生系。工系:拓族識。
敗:系不明合類 1 或 2→或混或常框。真張拉須至少有元唯張行(壓下鬆之索)。無唯張元→非張拉,重分為常桁或框施標構析。
各節算靜衡、定預應態(無外載之內張壓)、驗諸索仍張。
## Prestress Equilibrium
- **Equilibrium matrix A**: [dj] x [b] = [size]
- **Rank of A**: [value]
- **Self-stress states (s)**: s = b - rank(A) = [value]
- **Self-stress feasibility**: [all cables in tension? Yes/No]
- **Minimum cable tension**: t_min = [value]
- **Critical external load**: F_crit = [value]
| Member | Type | Force Density | Force | Status |
|--------|-------|---------------|---------|-------------|
| S1 | strut | [negative] | [value] | compression |
| C1 | cable | [positive] | [value] | tension |
得:自應態算、物可實預應(諸索張、諸柱壓)得、載量估。
敗:無自應態保諸索張→拓不支張拉預應。或(a)關聯矩誤、(b)系需加索、(c)為機非張拉。大系用力密法(Schek, 1974)或數零空算非手算。
定張拉剛(對微擾穩)或機(有零能變模)。
施擴 Maxwell 律:d 維針節框,b 桿、j 節、k 運限(支)、s 自應態、m 微機:
b - dj + k + s = m
此關桿節限於自應與機態之衡。
由衡矩算:rank(A) = b - s。機數 m = dj - k - rank(A)。m = 0→構一階剛。m > 0→須察預應穩。
預應穩測:各機模 q,算二階能 E_2 = q^T * G * q,G 為幾剛矩(應力矩)。若諸機模 E_2 > 0,張拉為預應穩(Connelly 與 Whiteley,1996)。此即張拉得剛——非由桿數,乃由預應穩機。
分剛:
## Stability Analysis (Maxwell's Criterion)
- **Bars (b)**: [value]
- **Joints (j)**: [value]
- **Dimension (d)**: [2 or 3]
- **Kinematic constraints (k)**: [value]
- **Rank of A**: [value]
- **Self-stress states (s)**: [value]
- **Mechanisms (m)**: [value]
- **Maxwell check**: b - dj + k + s = m --> [values]
- **Prestress stability**: [stable / unstable / N/A]
- **Rigidity class**: [determinate / indeterminate / prestress-stable / mechanism]
得:Maxwell 計行、機定,m > 0 評預應穩。構分為剛、預應穩、或機。
敗:構為機(m > 0 且非預應穩)→選:(a)增索以增 b 減 m,(b)增預應,(c)改拓。生系主動肌動肌球收續調預應以維穩——細胞為自調張拉。
若系生釋,圖至 Ingber 細胞張拉模而察跨尺一致。純工系跳此。
## Cross-Scale Biological Tensegrity
| Scale | Compression | Tension | Prestress Source | Nodes |
|------------|--------------------|----------------------|-----------------------|--------------------|
| Molecular | Tubulin dimers | Actin/IF subunits | ATP/GTP hydrolysis | Protein complexes |
| Cellular | Microtubules | Actin cortex + IFs | Actomyosin | Focal adhesions |
| Tissue | Cells (turgor) | ECM (collagen) | Cell contractility | Cell-ECM junctions |
| Organ | Bones | Muscles + fascia | Muscle tone | Joints |
### Mechanotransduction Pathway
ECM --> integrin --> focal adhesion --> actin cortex --> IF --> nuclear lamina --> chromatin
得:各相關尺生張拉圖附壓、張、預應源、節識。跨尺力傳文。
敗:跨尺圖斷(無尺間明張續)→文缺。非諸生構諸尺皆張拉。脊於肌骨階為張拉(骨=柱、肌膜=索)而個椎內為常壓構。
合前析為系張拉整之末評。
