Center of Gravity Detection for Railway Cars

Graduate School of Tokyo University of Marine Science and Technology, Japan

ABSTRACT: Three-dimensional detection of the center of gravity (D3DCG) is an innovation to prevent rollover accidents of moving objects because D3DCG can detect the center of gravity without measuring either the weight (m) or spring rate (k). The authors have explored the use of D3DCG with railways. Conducting actual experiments for Japanese railways, this study demonstrated that D3DCG is a safe technology for use with railways because of the low cost utilization and the flexible installation on any railway.
