摘　　要：随着煤矿行业的发展,矿用装载机成为需求最大的采集设备。由于我国装载机的设计主要以传统的设计方法为主,缺乏系统的设计方案,在其设计阶段,为了确定其使用寿命,需要对其进行室内台架疲劳试验,因此载荷谱的编制变得尤为重要。以某型号矿用装载机传动系统为研究对象,根据制定的工况进行实车测试实验,对采集的载荷信号进行消除信号和异常值剔除处理,利用雨流计数法进行统计计数,然后进行载荷数据外推,最终编制成8级程序载荷谱。从而为今后装载机设计提供依据。With the development of coal mining industry,mining loader to become the largest demand for acquisition equipment. As China loader design mainly in the traditional design methods,the lack of systematic design. In the design stage,in order to determine its service life,it needs to carry on indoor bench fatigue test,so the compilation of load spectrum becomes more and more important. Taking the transmission system of mining loader as research object,a real vehicle road test is carried out according to typical designed condition. The signals eliminates and outliers eliminating for the acquisition of load signals is carried out. It has a statistical counting for the acquisition of load signals by using rain-flow counting method. Then it makes a load data extrapolation and weaves into an 8 program load spectrum,therefore,it can provide a basis for the design of mining loader in the future.
