摘 要：
为对某高空作业平台进行结构优化,利用理论力学知识建立该结构简化的力学模型,对结构中各构件所承受的约束反力进行计算,以计算结果为指导考虑到结构的实际情况及实际的应力状态确定测点位置,并进行应力测量。结果表明:高空作业平台在各种载荷工况下构件在下降过程中承受的应力值远大于上升过程,冲击作用不容忽视;各构件的最大应力值发生在构件中间位置铰链连接处;结构的最大应力值多发生在与液压装置连接的构件的中点处;静力计算结果可很好地指导测点的布局,减少测量工作量。应力测量结果为高空作业平台强度的优化设计提供了基础,应将课堂教学与工程实际问题相结合以培养学生解决工程问题的能力,为企业输送更多的优秀人才。

摘 要：
In order to optimize structure of aerial work platform,it was established the simplified mechanical model of the structure based on theory of mechanics at first.And then constraint reaction forces of each component of the structure were calculated,measuring point were determined based on the calculation results for considering the actual situation of the structure and the actual stress state and stress was measured.The results showed that the stress values of aerial work platform under various load conditions in the process of falling are always greater than that of rising process,the impacting action should not be ignored;the maximum stress value of each bar occurs in the middle position hinge connecting rod;the maximum stress values of the structure occurs in the midpoint of the bar which is connected with the hydraulic bar;the static calculation results can well guide the layout of measuring points and reduce the measurement workload.The stress measurement results provide the basis for the optimization design of strength for the aerial work platform,the classroom teaching should be combined with practical engineering problems to train students to solve engineering problems,transporting more outstanding talents for enterprises.
