回转平台与塔架一起构成排土机的上部回转机构,它承载了塔架、排料臂和受料臂的大部分重量,是排土机的中心支撑部件。对回转平台的板材结构以及其在工况下、非工况下的受力进行分析;在SolidWorks中建立结构的模型,利用其内含的Simulation有限元分析模块,对结构进行线性静态分析,获得了该板材结构的应力、应变以及安全系数图解,为设计板材时焊缝的合理布置以及回转平台稳定性的校核提供了重要的参考,对板材结构的优化设计具有着重要的指导意义。
The slewing platform together with the tower forms the upper slewing mechanism of the earthmoving machine, which carries most of the weight of the tower, discharge arm and receiving arm and is the central support for the earthmoving machine. The plate structure of the rotary platform and its under non-operating conditions under stress analysis; in SolidWorks to establish the structure of the model, the use of its included Simulation finite element analysis module, the structure of linear static analysis, access to The diagram of stress, strain and safety factor of the plate structure provides an important reference for the reasonable arrangement of the weld when designing the plate and the checking of the stability of the rotary platform. It has important guiding significance for the optimization design of the plate structure.
