This contribution summarizes the current state of research regarding so‐called sensor‐
integrating machine elements as an enabler of digitalization in mechanical engineering and …

An improved ultrasonic reflection coefficient phase model is proposed for lubricant film
thickness measurement with consideration to the influence of the solid layers. In the model …

Purpose The purpose of this study is to investigate the application of non-destructive testing
methods in measuring bearing oil film thickness to ensure that bearings are in a normal …

This paper establishes the mixed-lubrication and wear model to reciprocating of water seal
under the high-pressure of 100 MPa. Reciprocating movement thermal sources (RMTS) from …

A reliable O-ring seal is an important guarantee for the stable running of deep-sea hydraulic
systems and for the execution and completion of subsea tasks. Stress relaxation of rubber …

Researches on the reciprocating seals lubrication under elastic-hydrodynamic lubrication
(EHL) are mature, and leakage of failure criterion has been described with Couette flow for …

Lubrication film thickness and coating wear depth are two important parameters indicating
tribological condition in tribological elements. In this paper, a new ultrasonic model was …

Acoustic impedance is an important property used to interpret acoustic reflection
measurements in tests to determine oil film thickness, a critical parameter dictating efficiency …

The reliability of the reciprocating seal is the key to ensuring the regular operation of the
entire hydraulic system. Since friction in the sealing area under reciprocating conditions and …

Bearings play a key role in rolling mills, and the uniformity of their lubricant film directly
affects the degree of wear of bearings and the safety of equipment. Due to long-term stress …
