【摘要】：随着轮式装载机新技术不断涌现和人们对装载机性能要求的不断提高，现有的装载机性能评价指标已不能完全体现新技术的发展和要求，因而论文对轮式装载机性能评价指标进行分析研究，对现有装载机性能评价指标提出补充建议；轮式装载机性能试验费用高、周期长，仿真技术的发展为其提供了强有力的工具和手段，论文对装载机进行建模仿真研究，以便减少试验内容、缩短试验周期、节约试验成本。 首先，论文根据轮式装载机工况特点、发展趋势和现有轮式装载机国家标准，分析了装载机动力性、经济性和作业能力的评价指标现状，对现有的装载机评价指标提出了一些补充和改进建议；其次，完成了基于AMESim的轮式装载机的模型建立和仿真计算。主要完成了底盘系统、铲斗系统和转向系统建模，在装载机模型基础上建立性能评价指标的参数计算模型，对其动力性、经济性、作业能力的各项指标仿真计算，得到仿真结果；最后，将仿真结果与实测值进行对比，动力性、经济性、作业能力指标的仿真结果与实测值误差均在工程允许误差以内。仿真结果与试验结果一致性较好，建立的装载机仿真模型具有较好的实用性，，能满足工程试验的要求。 论文对轮式装载机评价指标提出补充，可以更准确评价装载机各项性能，同时体现新技术的应用与发展；基于AMESim软件建立轮式装载机的仿真模型，可以真实模拟装载机行走、作业情况，更简捷地获得装载机的各项性能评价指标，省去了复杂的试验，降低了成本。
[Abstract]:With the continuous emergence of new technology of wheel loader and the continuous improvement of the performance requirements of the loader, the existing performance evaluation indexes of the loader can not fully reflect the development and requirements of the new technology. Therefore, the performance evaluation index of wheel loader is analyzed and studied in this paper, and some supplementary suggestions are put forward for the performance evaluation index of wheel loader, the cost of performance test of wheel loader is high, the period is long, The development of simulation technology provides powerful tools and means for it. In order to reduce the content of the test, shorten the test period and save the cost of the test, the paper carries on the modeling and simulation research on the loader in order to reduce the test content, shorten the test period and save the test cost. Firstly, according to the characteristics of the wheel loader, the development trend and the current national standard of wheel loader, the paper analyzes the present situation of the evaluation index of the loader's power, economy and working ability. Some suggestions are put forward to improve the evaluation index of wheel loader. Secondly, the model building and simulation calculation of wheel loader based on AMESim are completed. The modeling of chassis system, bucket system and steering system is completed. Based on the loader model, the parameter calculation model of performance evaluation index is established. Finally, the simulation results are compared with the measured values. The simulation results of power, economy and operation capability are within the allowable error of engineering. The simulation results are in good agreement with the test results. The simulation model of the loader has good practicability and can meet the requirements of engineering tests. The evaluation index of wheel loader can be evaluated more accurately, and the application and development of new technology can be reflected. The simulation model of wheel loader based on AMESim software can be used to simulate the wheel loader. The performance evaluation indexes of the loader can be obtained more simply, which saves the complicated test and reduces the cost.
