Dynamic Simulation of Harmonic Gear Drives Considering Tooth Profiles Parameters Optimization [PDF]
Journal of Computers, 2012 Considering the fact that load distribution of the flexspline under alternating dynamic loads is complicated, and it’s difficult to measure the stress of the flexspline by experiment, a d ynamic simulation model of harmonic gear drives is established to study the intensity of the flexspline in the operating process of harmonic gear drives based ...

Systems of reciprocity in human–ocean relationships: Across time, place, language and culture
People and Nature, EarlyView.Abstract In the face of large‐scale marine environmental challenges, solutions that meaningfully capture the complexity of socio‐cultural and economic factors contributing to such issues—and their solutions—are urgently needed. This scoping review explores examples of reciprocity in human–ocean relationships to inform the conceptual underpinning and ...
