Effect of higher-order roll ratio modification coefficient on meshing behavior of aviation spiral bevel gear

Journal of Advanced Mechanical Design, Systems, and Manufacturing
The increasingly demanding service conditions for aviation spiral bevel gears necessitate higher machining accuracy of the tooth surfaces. The conventional constant roll ratio, a critical parameter governing the relative motion between the cradle and the

Finite Difference Modeling of the Interstand Evolutions of Profile and Residual Stress during Hot Strip Rolling

Metals, 2020
Elastic recovery and viscoplastic stress relaxation occur in the interstand of hot rolling, impacting the evolutions of strip profile and residual stress, which are major concerns for obtaining high-quality flat products.

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Evolution of internal stresses in rolled Zr702α [PDF]

Acta Materialia, 2002
Internal stresses due to anisotropic thermal and plastic properties were investigated in a rolled Zirconium-alpha. The thermal stresses induced by a cooling process were predicted using a self-consistent model and compared with experimental results obtained by X-ray diffraction.

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Influence of Wear-Induced Turning on the Roll’s Fatigue Life

Metals
Friction-induced wear during the rolling process needs periodic remachining of caliber roll grooves, which increases operational costs and reduces roll fatigue life.

Explicit Nonlinear Finite Element Geometric Analysis of Parabolic Leaf Springs under Various Loads

The Scientific World Journal, 2013
This study describes the effects of bounce, brake, and roll behavior of a bus toward its leaf spring suspension systems. Parabolic leaf springs are designed based on vertical deflection and stress; however, loads are practically derived from various ...

Stress calculation of Plate Rolling

Transactions of the Japan Society of Mechanical Engineers, 1949
圧延機の円〓ロールの圧延部における円弧を, 頂点の曲率半径がロール半径に等しき双曲線にて置き換え, ロール圧力σ, 圧延方向の応力σnおよびロ一ル而の摩擦力τを考慮に入れて力の平衡式を立て, これに最大せん断応力説による塑性変形條件を入れてパラメータ表現法によつて解を得た.ロール面と圧延素材間の相対速度の方向によつてτの方向は変り, ために生ずる2種の式に, 入口と出口とにおいてσn=0,相対速度=0の所にて両式のσnが等しき條件より未定数を定めた.終りに数値例題を附記して計算の経路を示した.
