Product Description
- Load-Deflection Linearity: Maintains ≤3% deviation from Hooke's Law within 20-70% of maximum deflection, ensuring predictable force output (typical range: 5-500N)
- Elastic Recovery: ≥98% shape recovery after cyclic loading (10⁶ cycles at 70% rated load), validated via laser displacement monitoring
- Stiffness Consistency: Batch-to-batch stiffness variation ≤±5% (per ISO 16142), achieved through CNC forming with ±0.01mm wave height tolerance
- Shock Absorption: Absorbs 30-40% more energy than conventional coil springs of equal axial space, with impact stress distributed across wave crests
- Peak Load Capacity: Withstands 150% of rated load for 10ms without plastic deformation (tested per ASTM E23)
- Material-Dependent Performance:
- 60Si2MnA: Impact toughness 120 J/cm² (charpy test at -40°C)
- Inconel718: Maintains 90% impact resistance at 650°C
- Material Selection:
Material Fatigue Life (10⁶ cycles) Operating Temp Range 60Si2MnA ≥100 -40°C to 200°C Inconel718 ≥200 -270°C to 650°C SUS316 ≥150 -200°C to 450°C - Surface Treatments:
