在轮胎起重机总体设计过程中,当选定了柴油机和液力变矩器以后,首先要确定柴油机和变矩器的匹配功率、匹配扭矩,然后才能确定柴油机和变矩器的共同工作曲线。本文提出柴油机和变矩器匹配功率、匹配扭矩的计算方法及用解析方法确定柴油机和变矩器共同工作曲线,因为用解析方法计算方便、准确,更适合上机计算,并可克服做图不准确的缺点。
In the overall design process of the tire crane, after the diesel engine and the torque converter are selected, the matching power between the diesel engine and the torque converter must be determined first, and the torque must be matched before the common working curve of the diesel engine and the torque converter can be determined. In this paper, the calculation method of matching power and matching torque of diesel engine and torque converter is proposed, and the working curve between diesel engine and torque converter is determined by analytical method. Because it is convenient and accurate to calculate with analytical method, it is more suitable for on-machine calculation, Accurate shortcomings.
