转台是汽车起重机重要结构组件。由于其结构形状和受载情况较复杂,静不定次数高,精确计算难度大。传统方法是把它作为自由支承的悬臂梁进行分析,以致计算结果十分粗糙,远不能满足工程的实际需要。而了解转台在各种载荷工况下的变形和应力分布状况,又恰恰 Turntable truck crane is an important structural component. Due to its complex structure and loading conditions, the number of static uncertainties is high, and the precise calculation is difficult. The traditional method is to analyze it as a free-standing cantilever, so that the calculation results are very rough, far from meeting the actual needs of the project. And understand turntable in a variety of load conditions of deformation and stress distribution, but also precisely
