Squeak in hip endoprosthesis systems: An experimental study and a numerical technique to analyze design variants

The influence of component design, bearing clearance and axial load on the squeaking characteristics of ceramic hip articulations

“…This finding cannot directly be transferred to the clinical situation, in which clearance affects the lubrication and hence the friction in the bearing articulation (Brockett et al, 2007;Mabuchi et al, 2004). Interruption of fluid film lubrication is related to higher friction, which is the basic requirement for the excitation of vibrations (Brockett et al, 2008;Weiss et al, 2010). This is similar to the situation with respect to cup design, which does not play a direct role for the dynamics of the system, but an indirect one since the design and positioning of the cup (as well as the stem) can affect the risk of metal transfer and subluxation.…”

“…Squeaking of ceramic-on-ceramic total hip replacements (THR) has become a frequently discussed phenomenon (Keurentjes et al, 2008;Mai et al, 2010;Restrepo et al, 2010a;Walter et al, 2007Walter et al, , 2008Mai et al, 2010;Chevillotte et al, 2010;Weiss et al, 2010). Squeaking occurs due to vibrations of the hip joint components in the audible range (Sariali et al, 2010;Weiss et al, 2010).…”

“…Squeaking occurs due to vibrations of the hip joint components in the audible range (Sariali et al, 2010;Weiss et al, 2010). These are excited by friction acting in the joint articulation between the ceramic ball head and the ceramic cup inlay .…”

A review of squeaking in ceramic total hip prostheses

“…It has been computationally and experimentally demonstrated that squeaking can be associated with the articulation of the femoral head and cup as well as high friction from an engineering point of view [19], namely friction-induced vibration [48,49]. However, hip squeaking is multifactorial as indicated in Fig.…”

Friction-induced noise of gear system with lead screw and nut: Mode-coupling instability

“…From the linear stability theory, the onset of friction noise is determined by the positive real parts of eigenvalues in the linearized equations of motion. The modeling of the friction-induced noise problem in literature has been limited to some mechanical applications such as automotive brake squeal [3,4] and hip squeak [5] by use of the commercial finite element software. In fact, the finite element simulation on the complex eigenvalue analysis often requires enormous computing time even for a single system configuration which impedes the progress of analysis.…”
