ABSTRACT
the mated socket.
The pin-socket contact pair was applied a very small amplitude sinusoidal vibration
load to simulate the fret between the contact faces. Calculated results such as Contact
force, relative transfer function and stress state were extracted. A series of simulation
were implemented according to orthogonal method. Four variables including fretting
amplitude (A ), vibration frequency (f ), inner diameter of the socket (D, or positive
pressure) and Coefficient of friction (μ) were selected. Range analysis indicate that inner
diameter of the socket is the major effect factor compared to other three parameters when
the value of the relative transfer function and the contact force were taken as the test target
to describe the fretting of contact pair in micro-rectangular electrical connector. Finally,
the effect trend and degree of these four factors to fretting characteristics between twist
pin and socket contact pair present not totally identical.
