旋臂起重机因其高效、节能、占地面积小、易于维修等特点,特别适合短距吊运作业,受到越来越多的关注。其中曲臂式旋臂起重机比常规的旋臂起重机多出一个铰点,在设计时用公式算法需要对其进行简化计算,且不能准确地表述实际情况。为了进一步得到精确解,根据旋臂起重机的结构特点,可以利用ANSYS软件进行整机建模,并可以对起重机进行静力分析及模态分析,有利于在使用过程中对该机结构危险部位进行控制,对设计制造及实际使用具有指导意义。
Due to its high efficiency, energy saving, small footprint and easy maintenance, the jib crane is particularly suitable for short-distance lifting operations and is receiving more and more attention. Among them, the jib jib crane has a more hinge point than the conventional jib crane, and the formula algorithm needs to be simplified and can not accurately describe the actual situation. In order to get the exact solution, according to the structural characteristics of the jib crane, it can use ANSYS software to machine modeling, and static analysis and modal analysis of the crane, is conducive to the dangerous parts of the machine structure during use Control, the design and manufacture and practical guidance.
