转台式分拣装置本体静动态特性分析

Abstract

分拣装置有限元分析是利用数字近似的方法对其真实物理系统进行模拟，可以准确预测该分拣装置的性能，缩短其研发周期。本文根据所需本体结构及性能要求，确立总体设计方案和机械手结构，以转台式分拣装置为研究对象，分析得到机械手的应力、位移云图和静刚度强度情况，并通过模态分析找到了前十阶的固有频率和主振型以及机械手臂末端某一节点随模态变化的位移曲线图，为其薄弱危险环节进一步优化设计提供了理论依据。 The finite element analysis of the sorting device is to simulate the real physical system by means of digital approximation, which can accurately predict the performance of the sorting device and shorten its development cycle. According to the required body structure and performance re-quirements, the overall design scheme and the structure of the manipulator are established. The stress and displacement cloud charts and static stiffness of the manipulator are analyzed by the turntable sorting device. The top ten-step natural frequency and main vibration type, as well as the displacement curve of a node at the end of the manipulator with the modal change are obtained, which provide the theoretical basis for the further optimization design of the weak dangerous link.
