Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Study of the coefficient of friction and forward slip in cold rolling of stainless steel AISI 430 in Sendzimir mills

Journal of Materials Research and Technology
For most AISI 430 stainless steel applications, aesthetic appeal is mandatory. To avoid the generation of scratches on the strip surface during cold rolling on a Sendzimir mill, forward and backward slip are required to synchronize the speed of the ...

Rolling Friction at High Speed

Bulletin of JSME, 1962
In order to analyze the operating characteristics of the high speed rolling bearings, it is necessary to investigate the rolling friction at high speed. But the attempts to measure the rolling friction have hitherto been confined to low rolling speed.
