摘　　要：针对传统的隔振平台在移动场景下难以满足高效减振的需求,本文在分析机床隔振、液压式减震器的基础上,基于柔性阻尼器原理,设计了一种能同时吸收移动中振动的柔性减震装置,包括主减振Y方向的平衡结构和副减振X方向的凸轮导轨结构,根据实际选型和工作情况,设计计算机械结构;进一步用三维建模软件对各个部件建立模型,对其进行装配;最后通过对隔振平台的运动学和动力学仿真,验证了设计方案的可行性,结果显示:装置对主减振主方向Y方向振幅减少为原来的0.6%;辅方向X方向上振幅减少为原来的30%。说明该方案能够在设计场景下起到良好的减振效果,为移动作业装备的高精度运行提供技术支持。In response to the difficulty of traditional vibration isolation platforms in meeting the requirements of efficient vibration reduction in mobile scenarios, we analyzed machine tool vibration isolation and hydraulic shock absorbers. Based on the principle of flexible dampers, a flexible vibration reduction device that can simultaneously absorb vibration during movement is designed, including a balance structure in the Y direction of the main vibration reduction and a cam guide mechanism in the X direction of the secondary vibration reduction. According to actual selection and working conditions, a computational mechanical structure is designed. Further models of each component using 3D modeling software were established and assembled. Finally, the feasibility of the design scheme was verified through kinematic and dynamic simulations of the vibration isolation platform. The results showed that the device reduced the amplitude in the Y direction of the main damping direction by 0.6% of the original value;The amplitude in the X direction of the auxiliary direction was reduced to 30% of its original value. The scheme can achieve a good vibration reduction effect in the design scenario, providing technical support for the high-precision op
