摘要:
连接杆件在汽车及机械结构中被广泛使用,振动破坏是其主要失效形式.影响连接杆件振动的主要因素是杆件的动态特性.通过建立连接杆件系统的振动学方程,并利用有限元软件MIDAS对连接杆件进行模态分析.分析结果表明,在位置固定、横截面积一定的情况下,各个振型的径弦比与固有频率、角度与固有频率存在一定的规律,且此结论在某型号的半挂牵引车上得到了验证,并为连接杆件的结构设计或者进一步的结构优化提供了理论依据.
Abstract:
The connecting rod was widely used in the automotive and mechanical structure of which main failure mode is vibration-damage.Vibration-damage was the main failure mode of connecting rod.The dynamic characteristics of the connecting rod were the main factors which affect the vibration of it.Therefore,by establishing vibration equation and using finite element software MIDAS,the modal analysis was done and the results showed that there was a certain regularity between the diameter ratio and,the natural frequencies,the angle and natural frequencies of the various model shapes at a fixed location and cross-section.This conclusion had been verified on the tractor-trailer.It provided a theoretical basis for the structural design or further structural optimization.
