Monitoring of friction-related failures using diffusion maps of acoustic time series

S. A. Shevchik et al.

Summary: Friction-related failures are a common cause of catastrophic damage in mechanical systems, with scuffing being one of the most concerning mechanisms. In this study, a probabilistic analysis of acoustic signals recorded synchronously with the coefficient of friction was proposed for real-life experiments. Through analyzing the dynamic behavior of friction, surface states and upcoming failures could be identified.

A parametric study on the effect of uniformly-induced curvature on the deformational capacity of steel onshore pipelines based on a novel material characterization procedure

Onyekachi Ndubuaku et al.

Summary: This study investigates the response of pipelines to bending deformation and develops a set of design equations for predicting critical values. The use of a novel stress-strain model effectively addresses the shortcomings of current equations related to material stress-strain curve characterization.

Analysis on the interference assembly of camshaft with knurled tube and cam

Xiaoming Huang et al.

Summary: Interference joint is an advanced assembly method for camshaft, with joining force and connection strength being key aspects of the system. Experimental results provide empirical formulas for torque capacity, joining force, and interference of the camshaft. Metallographic observation reveals changes in the metal flow line of the knurled tube during the joining process.
