摘要:
针对某项目转向架构架使用寿命无法满足运营要求的情况,通过对线路动应力测试数据的时域图和频域图对比分析,提出优化结构方案,并运用理论计算、有限元分析以及实际运行线路的测试,对优化结构方案进行验证。优化结构关键部位测点应力大幅降低,所有测点等效应力均小于标准限度70 MPa,满足了车辆正常使用寿命的要求。
Abstract:
According to the service life of bogie frame of a project can not meet the operation requirements, by comparing and analyzing the time-domain and frequency-domain diagrams of line dynamic stress test data, the optimal structure scheme was put forward. The optimized structure scheme was verified by theoretical calculation, finite element analysis and actual operation line test. The stress of the key parts of the optimized structure was greatly reduced, and the equivalent stress of all measuring points was less than the standard limit of 70 MPa, which met the requirements of normal service life of vehicles.
