fatigue life testing of automotive components
nondestructive analysis | automotive materials performance |
environmental reliability | auto parts cleanliness |
fatigue life testing | automobile pipeline performance |
automobile coating performance |
test significance:
fatigue is the main form of damaged auto parts, in actual use, due to changing load and speed of these parts are usually subject to periodic alternating stress until the destruction, which is known as fatigue failure, mileage at failure or the number of cycles of fatigue life.
testing purposes:
analog auto parts repeatedly stretched in the actual use of the car, compression, bending, torsion and bending fatigue tests, etc., and to assess the service life of components.
the main test items:
low cycle fatigue
creep test
tension - torsional fatigue test
determination of s-n curves
load - displacement fatigue test
car air conditioning vent endurance test
handle inside car endurance test
car cup holder endurance test
items within the box car endurance test
cars in the electronic key life testing
combination switch durability test car
