The rubber herringbone spring is used as a vibration-damping component of the suspension system of railway engineering vehicles. It is usually used as an axle box spring. It can obtain different matching spring stiffness in the longitudinal, lateral and vertical directions. It has a simple structure and absorbs high-frequency vibration or noise. advantage. The static stiffness of the rubber herringbone spring includes vertical, longitudinal and lateral stiffness, where the vertical stiffness is related to the vertical damping performance of the vehicle, the longitudinal and lateral stiffness are related to the dynamic performance of the vehicle, and the wheel-to-rail when the vehicle is traveling on a curve The impact. The fatigue performance of rubber herringbone spring refers to the condition of rubber part temperature rise, fatigue fracture and rubber and metal peeling when the rubber herringbone spring vibrates in vertical, horizontal and vertical directions under train cycle and non-periodic stress. In order to ensure the safety of the vehicle operation, static rubber stiffness test and fatigue performance test must be carried out on the rubber herringbone spring. Http://news.chinawj.com.cn
