Abstract For the helical gear fault diagnosis investigation, it is essential to establish a pitting dynamics model that incorporates several nonlinear parameters simulate characteristics. This paper proposes multi-degree-of-freedom analytical dynamic of pair under fault, introducing stiffness and damping matrix lubricant film, variable friction coefficient elastohydrodynamic lubrication (EHL), measured meshing profile error. Contact fatigue experiments are carried out with transmission test...
Being a key component of the transmission system, needle bearing’s performance and service life affects overall mechanical equipment. This study takes bearings composed AISI 52100 steel as research object studies effect carbonitriding surface strengthening treatment on bearing friction, wear, fatigue life. The carbon nitrogen co-infiltration surface-strengthening method was employed to prepare cylindrical disc samples. hardness, residual austenite content, microscopic morphology organization...
Abstract Fiber-reinforced non-calcined coal gangue-based polymer concrete (BFCGGC) was synthesized utilizing gangue, slag, an alkali exciter solution, and coarse fine aggregates, alongside basalt fibers as primary constituents. Mechanical characteristics of BFCGGC were investigated by varying the mass fractions fibers, while its micro-mechanism examined using scanning electron microscopy. The findings indicated a trend in compressive strength BFCGGC, initially ascending subsequently...
