针对救援工况的特殊性和复杂性,以国产某型号提升机为基础,进行救援提升机非标设计。首先运用传统的解析方法对主轴在正常及非正常载荷工况下分别进行强度计算与校核;接着利用UG对救援提升机主轴构建3D模型,并导入ANSYS中进行2种工况下的强度分析,求出其应力、应变分布状况,找出危险截面。 Aiming at the particularity and complexity of the rescue operation, a non-standard design of rescue elevator is based on a certain type of domestic elevator. Firstly, the traditional analytical method was used to calculate and check the strength of the spindles under normal and abnormal load conditions respectively. Then, the 3D model of rescue lifter spindles was built by using UG and imported into ANSYS for strength analysis in two conditions , Find the stress and strain distribution, find the dangerous section.
