摘要
为准确快速得出小吨位侧面叉车动力特性以及发动机与液力变矩器联合工作中的联合工作特点,分析了侧面叉车选配某型号4缸发动机及YBQ244变矩器的设计方案,计算不同变矩比工作情况下的发动机和变矩器的联合工作点工作特性;并利用Matlab GUI及一维插值数组算法,根据动力匹配方法原则直接显示联合工作坐标点,使用Matlab GUI图形界面系统计算分析得出该车型不同变矩比同牵引力变化规律曲线.结果表明:在转速比i=0.2～0.6工作状态下,联合工作转速n=2 000～2 200之间发动机输出扭矩变化率不足3%,工作最为稳定;该车型驱动桥以及轮胎型号的整车动力匹配状况最大牵引力为1.5 t.
In order to obtain joint operating characteristics between an engine and a torque converter on small side loader, the matching performance of three-ton side loader with the engine of a 4-cylinder engine and the torque converter of YBQ244 was analyzed. The joint operating working points between the engine and the torque converter at different torque ratio were calculated. In this article, joint work coordinates were displayed directly by using Matlab GUI and one-dimensional interpolation algorithm. The results show that the rate of change of the engine output torque is less than 3% when i =0.2~0.6 and the joint work between the speed of n =2000~2200. Also, the curve of variation about the traction with different torque ratio was calculated and analyzed with Matlab GUI. The maximum tractive force is 1.5 tons.
