工程机械波动载荷分析与模拟方法研究

波动载荷对工程机械的动力性、燃油经济性以及系统的安全性有着重要的影响.试验在分析波动载荷的基础上,利用随机统计关系提出工程机械波动载荷试验数据的处理方法,将波动载荷非平稳试验数据分解为非平稳的确定性分量与平稳的随机性分量两部分,并提出了相应的函数表达式以及对影响因素进行了分析.最后通过AMESIM仿真软件对波动载荷试验数据进行仿真模拟,给出了仿真方法.

An analysis of fluctuations load and simulation method on construction machinery

Fluctuating load of construction machinery has an important impact on its power,fuel economy and system security.On the basis of the analysis of fluctuating load,the fluctuating load experimental data processing methods of construction machinery was proposed by using random statistical relationship.The non-stationary experimental data of fluctuating load were decomposed into a non stationary deterministic component and a smooth randomness component,and the corresponding function expression was proposed and the influencing factors were analyzed.Finally,through AMESIM simulation software simulated,the simulation method was given.The simulation results were consistent with the experimental data processing.
