CORRELATION BETWEEN TRIBOFILM FORMATION AND FRICTION COEFFICIENT IN CONTINUOUSLY VARIABLE TRANSMISSION AT THE INITIAL STAGE OF RUBBING

Correlation between Tribofilm Formation and Friction Coefficient in Continuously Variable Transmission at the Initial Stage of Rubbing

To improve the transmission efficiency of a continuously variable transmission (CVT) system, it is effective to form a tribofilm with higher friction coefficient.Therefore, understanding of the correlation between the tribofilm formation and friction coefficient in a CVT fluid has been a great deal.In Console and Display Board this study, the tribo

Performance of Hamiltonian Monte Carlo and No-U-Turn Sampler for estimating genetic parameters and breeding values

Abstract Background Hamiltonian Monte Carlo is one of the algorithms of the Markov chain Monte Carlo method that uses Hamiltonian dynamics to propose samples that follow a target distribution.The method can avoid the random walk behavior to achieve a more effective and consistent exploration of the probability space and sensitivity to correlated pa

Structural Design of a Large-Scale 3D-Printed High-Altitude Propeller: Methodology and Experimental Validation

This paper presents an original approach to the structural design and analysis of a 3D-printed thermoplastic-core propeller blade for high-altitude UAVs.A macroscale linear isotropic numerical model for the behavior of 3D-printed parts (in Tough PLA, as well as ABS) is fed with values from tensile and bending testing on standard specimens (ISO 527-
