8.2.1.4 Bear Thermal Expansion in Mind

 

  • compensate for
    expansion with
    elastic clamping
    o provide spring washers

o provide spring
jointing elements

  • introduce intermediate compliant layers

  • design clearance between parts such that differences in thermal expansion coefficient do not lead to mismatches
    • D > d(STT+1)
      at assembly
