摘要:
将车辆与地面结构视为综合体系,用数学模型描述车辆与地面结构接触面的平整度,建立随机场; 研究在随机振动激励下发生的车辆对地面结构的各种运动荷载; 分3种情况研究各种运动荷载作用下各类地面结构的动力响应.此项成果完全改变了过去以稳态点源荷载,甚至以静力荷载作为动力源,又将车辆和地面结构分开,进行单项研究等不符合实际的研究方法,从而开创了车辆-地面结构动力学理论的新体系.
Abstract:
Vehicle and ground structure is assumed to be a group system, a mathematical model is adopted to describe the touch roughness between vehicle and ground pavement structure, and a random field is set up. Extending research on various moving loads on ground structure are studied under vehicle random vibration. The dynamic response of various kinds of ground structure is also discussed under various moving loads in three cases. Achievements of this paper lead to a new stage and completely transform the traditional research method in which the stabilized point load even the static load was adopted as the dynamic source and the vehicle and ground structure were separated into two individual parts.
