2 · Selection
8 × AWRI 318-40 in 45° compression/roll, four opposed pairs on two rails, upper frame to the skid, AES-40 elastomer end-stops fore and aft at 11 mm, lateral snubbers at 11 mm, slack safety chains at four corners.
| Load line | Max static, kN | Max defl., mm | Kv, N/mm | Ks, N/mm |
|---|---|---|---|---|
| 45° compression/roll, as installed | 17.37 | 137.2 | 2158 | 529 |
3 · Static loads
Corner factor (1 + eL/a)(1 + eT/b) = 1.139. Nominal 9.20 kN, worst 10.48 kN per isolator: 53 % to 60 % of rating. Static sag 4.3 mm on Kv.
4 · Vibration
fn = 7.64 Hz on Kv, vertical and lateral. Isolation starts at 10.8 Hz. Transmissibility at the 30 Hz mode 0.107 (89 % attenuation); frequency ratio 3.9, above the minimum of 3.
5 · Shock
| Road | Input | fs on Ks | On cargo | Limit | Travel, worst corner | Result |
|---|---|---|---|---|---|---|
| R1 | 3 g · 20 ms | 3.78 Hz | 0.76 g | 3 g | 14 / 137 mm | Pass |
| R2 | 5 g · 15 ms | 3.78 Hz | 0.95 g | 3 g | 18 / 137 mm | Pass |
| R3 | 8 g · 15 ms | 3.78 Hz | 1.53 g | 3 g | 29 / 137 mm | Pass |
CargoRide · Road-Transport IsolationSample report6 · Braking, acceleration and end-stops
Horizontal secant rate 8 × 529 = 4 232 N/mm. Travel at 0.5 g 8.7 mm, at 0.8 g 13.9 mm. Stop gap 10.9 mm (1.25 × 0.5 g travel). Emergency 1.0 g: stops carry 27.6 kN, 13.8 kN per face stop, rated ×1.5 → AES-40. Rearward 0.5 g stays inside the gap.
7 · Rocking and tipping
Rigid threshold (B/2)/hCG = 0.85 g. At 0.7 g side: roll 0.71°, roof sway 34 mm, light-side isolators keep 1.6 kN compression. No uplift; twist-locks and retainer bolts are not in tension.
8 · Compliance summary
| Requirement | As selected | Status |
|---|---|---|
| Static capacity, worst corner | 60 % of 17.37 kN | Pass |
| Decoupling from 30 Hz mode | ratio 3.9, 89 % attenuation | Pass |
| Shock ≤ 3 g at R3 | 1.53 g | Pass |
| Travel within stroke | 29 of 137.2 mm (21 %) | Pass |
| Braking travel controlled | stops at 10.9 mm | Pass |
| Tipping at 0.7 g | no uplift | Pass |
9 · Open items and installation notes
- Confirm CG by weighing at four points before the frame is drilled.
- Set stop gaps with shims after the cargo is lowered, isolators loaded.
- Torque retainer-bar fasteners to the data-sheet value; recheck after the first 100 km.
- First-article static stiffness test on one isolator; the prediction above will be revised to the measured rate.
Note. Stiffness and performance values are catalogue values and vary with installation, load direction and environment. The first measured stiffness of the production lot will be reported and this selection revised on it. For high-value cargo Adoni Tech recommends a test-piece order before bulk production. Adoni Tech accepts no liability for deviations arising from unvalidated field conditions.
