Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Life Evaluation of High-speed EMU Variable Gauge Bogie Axle Box Bearing under Partial Load

机车电传动, 2020
The life of the axle box bearing of a high-speed EMU variable gauge bogie was evaluated. The axle box bearing should take two kinds of gauge and bear partial load due to the influence of the wheel track distance, thus producing the partial load effect ...

SYNTHESIS OF DOUBLE-LOBED CAM MECHANISMS WITH TRANSLATING DOUBLE - ROLLER FOLLOWER

International Conference on Technics, Technologies and Education, 2018
Two rational mathematical models for synthesis of mechanisms with conjugate disk cams translating with offset roller follower are derived from the equivalent four-bar linkage theory. They are linear and comparable in their relative simplicity, applicability and principle accuracy. The re-sults obtained from one model are verified by another, so any

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Mechanical Hybrid KERS Based on Toroidal Traction Drives: An Example of Smart Tribological Design to Improve Terrestrial Vehicle Performance [PDF]

, 2013
We analyse in terms of efficiency and traction capabilities a recently patented traction drive, referred to as the double roller full-toroidal variator (DFTV). We compare its performance with the single roller full-toroidal variator (SFTV) and the single

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

Advanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.
