振动(包括噪声)和冲击是许多工程结构和机械的一种工作状态或必须经历的一种环境。对于飞机、车、船等交通运输工具和某些机械,振动和冲击是它们的主要负载、正确地处理振动冲击问题,已是提高许多工业产品质量的关键技术之一。如果说在几十年前人们还不得不把明显的动载荷折算成静载荷加以分析,那末现在随着振动冲击理论和技术的迅速发展,已有可能按照“动”的本来面目来抑制振动和冲击的不良影响并利用它们的积极作用、所以振动冲击技术的每一步发展,都受到了广 Vibrations (including noise) and shocks are a working state or environment that many engineering structures and machinery must experience. It is one of the key technologies to improve the quality of many industrial products that the proper handling of the vibration impact problem is to transport vehicles and certain mechanical, vibration and impact of aircraft, vehicles and ships as their main load. If decades ago people still had to convert obvious dynamic loads to static loads and analyze them, then with the rapid development of the theory and technology of vibration shocks, it has been possible to suppress the vibration and vibration according to the original features of “moving” Impact of the adverse effects and the use of their positive role, so every step of the development of shock technology, have been widely
