Solutions for Bearing Fixation on Aluminum Water Pump Housing and Anchorage Enhancement Considering High Temperature Operation for Materials with Different Coefficient of Thermal Expansion 2012-36-0304
As part of any water pump development for engine cooling system,
the interaction between materials with different coefficient of
thermal expansion is unexceptional. Though in very specific
applications where the coolant temperature is over 115°C several
factors and variables can cause movement between parts because of
the interference and coefficient of thermal expansion interaction
combined with engine vibration and external loads.
These factors were listed and evaluated considering several
variables being validated physically and by simulation resulting on
an optimized method to enhance this kind of fixation.
