Powertrain Mounting

Isolation System: Fundamental Requirements

  • Locate and support powertrain mass
  • React external and internal forces without interference
  • Isolate external and internal forces
  • Must perform under severe conditions and provide fail safe
  • Manufacturability
  • Robustness
  • Assembly/maintainability
  • Weight and cost must meet program objectives

Defense-Specific Engine Mounting Challenges

  • Power Dense Engine = Higher Forces reacted through less mass
  • Tight deflection envelope
  • Limited freedom/flexibility for isolator placement
  • Substantial mobility, transportation and shock requirements
  • Structural rigidity?
  • Hardware delivery while design is still in-flux
  • Aggressive exterior acoustic requirement, interior must be inhabitable
