Design Difficulty
Core Challenges
- Stiffness-load matching: Precise parameter calculation, ±5% load tolerance required
- Fatigue life optimization: Avoid stress concentration, material selection critical
- Buckling control: Slenderness ratio (free height/mean diameter) ≤3; guide needed if exceeded
- Resonance avoidance: Match natural frequency to operating frequency
- Extreme condition adaptation: High/low temperature, corrosion, high speed
Difficulty Ranking
- Standard cylindrical: ★★☆☆☆, key challenge: Basic dimension tolerance control
- Variable-diameter: ★★★☆☆, key challenge: Stiffness matching across sections
- Variable-pitch: ★★★★☆, key challenge: Non-linear stiffness calculation
- Rectangular wire: ★★★★☆, key challenge: Complex stress distribution, cracking risk
- Precision miniature: ★★★★★, key challenge: Ultra-fine wire processing, inspection difficulty
