浅谈低温环境对JC型常接触弹性下旁承组成的影响

The influence of low temperature environment on JC constant contact elasticity

摘要

为满足大秦重载车辆安全运输需要，改善车辆的运行品质，针对大秦线高寒地区低温环境中对橡胶件的影响，开展了JC型常接触弹性下旁承组成低温性能的调研;分析了JC型常接触弹性下旁承组成在常温和-18℃工况下回弹比例的变化，选择和验证低温环境下JC型常接触弹性下旁承组成检修流程，为选择合适的下旁承检修公差提供了数据支撑。提出了解决影响低温状态对JC型常接触弹性下旁承组成的防范措施。通过一系列调研，完成了JC型常接触弹性下旁承组成在检修后，可以满足铁路货车在低温环境下的运行要求。

Abstract

In order to meet the needs of safe transportation of Daqin heavy-haul vehicles and improve the running quality of vehicles, the paper investigates the low temperature performance of the continuous contact elasticity under the PHC elasticity under the normal temperature and-18℃ , and the maintenance process of JC-type constant contact elasticity is selected and verified, and provides data support for the selection of appropriate secondary maintenance tolerance. Some preventive measures are proposed to solve the low temperature influence of JC constant contact elasticity. Through a series of investigations, the JC type constant contact elasticity under the lateral composition after maintenance, can meet the operation requirements of railway trucks in low temperature environment.
