摘要
对现有米轨货车用橡胶缓冲器性能进行了试验研究,以查明其使用效果不理想的原因,并为开发合适的缓冲器提供依据.试验结果表明,抗压模量过大和结构不合理是现用缓冲器性能不良的2个根本原因,导致冲击力、容量和质量过大、许用行程和吸收率过低、使用寿命低、缓冲效果差.此外,它们的制造与维修成本高,不宜作为米轨货车橡胶缓冲器的定型产品.
To find out the causes for the poor behaviors of the existing rubber draft gears and develop new rubber draft gears, the properties of the existing rubber draft gears of meter-gage railway freight cars were investigated experimentally. The experimental results reveal that high compression modulus and unreasonable structure design are two essential reasons for the poor behaviors of the rubber draft gears. As a result, the draft gears are high in impacting force, capacity and mass, low in allowance travel and energy absorption ratio, and short in service life. In addition, the cost of the draft gears is high in manufacturing and maintaining. Therefore, the existing draft gears are not suggested for meter-gage railway freight cars..
