简介

   本书是振动理论的典型教材之一,以讲述线性振动理论为主,从单自   由度、多自由度到连续体,从自由振动到强迫振动(包括无阻尼和有阻尼   情况),从间谐激励、冲击激励到一般激励,最后两章还介绍了随机振动   和非线性振动,内容丰富、叙述清晰、例题和习题与工程应用相结合,是   一本在国外受到普遍赞赏的畅销教材,至今已经出到第5版。    利用计算机分析多自由度、复杂结构系统动力响应的数值分析方法已   经成为解决工程振动问题必不可少的重要手段,在这方面本书为读者打下   了坚实的理论基础。第5版更加强了学生利用MATLAB等软件求解工程振动问   题能力的训练。    本书内容与我国多学时振动理论课程的教学要求相近,可以作为力学   、汽车等专业本科生和工科专业研究生振动理论课程的外文教材或参考书   ,也可供有关工程设计人员和研究人员参考。
