Abstract Most EHL numerical calculation methods considering both starved and flooded conditions, employ a fixed multiple of the Hertzian radius for normalization computational domain. These are often used to investigate influence lubricant supply on friction etc., but solutions obtained might be numerically starved. The present method utilizes an optimized domain ensure that not With this metho...

Daily line planning in the operation stage should satisfy fluctuating travel demand on different days and ensure stability. In this paper, we propose an approach of daily optimization for high-speed railway (HSR) lines to trade off system costs The plan is optimized by adjusting reference based baseline plan. A bi-level programming model constructed Stackelberg game theory describe interaction ...
