摘要
针对铰接式自卸汽车的开发,设计了相应的铰接式车架,使用有限元技术及Lanczos模态分析法得到了该种车架三维数字化模型的前6阶固有频率及相关振型。依据一定的汽车车架振动评价原则对该车架的动态特性进行了分析,认为该车架的动态特性符合要求。
An articulated frame was designed for the development of articulated dump truck in this paper.The first six natural frequencies and the natural mode shapes of the three-dimensional digital model of this kind of frame were calculated by using finite element technology and Lanczos mode analysis method.The dynamic characteristics of the frame were analyzed according to certain evaluation principles of the vehicle frame vibration,and the dynamic characteristics of the frame met the request.
