建立了起重机起重系统的动力学模型，提出了一种计算系统动载荷的高精度直接精细积分法。讨论了采用传统步进调速的普通起重机和采用变频调速技术的先进起重机的动态特性。计算结果表明，在相同的情况下，改进后的动载荷比一般情况下的动载荷要小得多。该方法具有精度高、计算时间短等优点，是分析起重机系统动态特性的一种简单有效的方法。
A dynamic model for load-lifting system of the crane was established in this paper, with which a high precision direct precise integration method was proposed for calculating the dynamic loads of the system. The dynamic characteristics of the general crane which used the traditional step speed regulation and advanced crane which used the variable frequency speed control technique were discussed. Calculating results show that the advanced have much smaller dynamic loads than the general in the same case. This method, with the advantages of high accuracy and taking less computing time, is simple and effective to analyze the dynamic characteristics of the crane system.
