摘　　要：概述了LM1836直线振动筛的工作原理,介绍了三维模型的建立及参数设置,并进行了结构动态特性分析,结果表明:固有频率远离激振频率,不会发生共振,谐响应分析得到的最大变形在安全范围内,振动筛性能稳定、结构可靠。The working principle of LM1836 linear vibration sieve was summarized,the establishment of three-dimensional model and parameter setting were introduced,and the dynamic characteristics of structure were analyzed. The results show that the natural frequency is far from the excitation frequency and resonance does not occur. The maximum deformation obtained by harmonic response analysis is within a safe range,and the vibration screen has stable performance and reliable structure.
