装载机发动机与液力变矩器之间的匹配对各自性能的发挥及整机牵引特性均有重要的影响.在拟合装载机发动机与液力变矩器有关特性曲线的基础上,以装载机的动力性为目标,建立发动机与液力变矩器匹配的优化模型,优化装载机发动机与液力变矩器的功率匹配,给出了算例并分析了优化结果.
发动机液力变矩器匹配事实证明一台性能良好的发动机与一台性能良好的液力变矩器共同工作,不一定同样能够获得良好的性能.其性能的好坏取决于两者的配合,即发动机与液力变矩器的匹配.充分发挥发动机与液力变矩器各自的优点,使它们有机的结合起来,使整个系统尽可能达到动力性最好、功率分配最佳以及发动机与液力变矩器共同工作时的功率输出最大,而油耗最低的最优匹配状态.本文根据发动机和液力变矩器各自特性分析发动机和液力变矩器的共同工作特性,并编制匹配软件,使匹配分析过程变得方便快捷.1 匹配过程1．1 发动机的速度特性根据发动机外特性曲线,绘制发动机的功率和转矩外特性曲线.由于发动机在作用于液力变矩器之前,还需要驱动其他一些辅助设备,需要消耗功率.因此在研究发动机和液力变矩器共同工作时,需知道发动机输入液力变矩器泵轮轴上的功率和转矩特性及特性曲线.1．2 液力变矩器原始特性对液力变.液力变矩器应月在牵引车上会使其性能得到极大的改善.针对TN518型牵引车发动机进行了液力变矩器选型、匹配的计算分析,使它们有机地结合起来,从而提高了牵引车的整体性能和良好的环保功效.
Power matching on torque-converter with diesel engine for wheel loader has important influence on each full playing performance and wheel loader full playing performance.The model of both diesel engine and torque-converter for wheel loader is presented.In this model,numerical approximation of some characteristics of diesel engine and torque-converter is carried out by the method of least square,and wheel loader power characteristic are taken as object.An example is given also.
Engine Torque Converter matching Facts have proved that a good performance of the engine with a hydraulic torque converter performance of the common good,not necessarily the same access to good performance.Its performance is good or bad depends on the two meet,that is,engine and hydraulic torque converter match.Engine and give full play to their respective advantages of hydraulic torque converter to enable them organic be combined so that the entire system of power,as far as possible to achieve the best,power distribution,as well as the best engine and hydraulic torque converter to work together when the greatest power output ,and optimal matching the lowest fuel consumption state.Based on the engine and hydraulic torque converter respective characteristics of the engine and hydraulic torque converter to work together character,and the preparation of matching software to enable matching analysis process becomes more convenient.1 matching process 1.1 engine under the speed of the engine,characteristic curve,rendering engine power and torque characteristics of the curve.The engine in the hydraulic torque converter in the role before,it is also necessary drive some other auxiliary equipment,power consumption needs.Therefore,in research engine and hydraulic torque converter to work together,to know that the importation of hydraulic torque converter engine on the pump shaft power and torque characteristics and characteristic curves.1.2 hydraulic torque converter on the hydraulic characteristics of the original hydraulic torque converter should be changed ...in the tractor on its performance will be greatly improved.Against TN518-type tractor engine liquid Selection of the torque converter,matching the calculation and analysis so that they are organically integrated with,thereby enhancing the overall performance of the tractor and good environmental effects.
