铁道车辆用低应力、低噪声轻量型车轮的开发

Development of the Light Wheels with Low Stress and Low Noise for Rolling Stock

利用有限元、边界元等方法,优化铁道车辆车轮的形状,采用试验验证新形状车轮的性能,证明新型车轮质量轻、应力小、噪声低。

The shape of railway wheels is optimized with the finite element method and boundary element method..The wheels with the new shape are tested to verify their performance, which proves that it has lightweight,small stress and low noise.
