中文摘要:
      针对偏心式压力机的振动隔离问题,采用理论推导、仿真分析和试验验证相结合的方法,研究偏心式压力机工作过程中产生的动载荷;结合橡胶材料的力学特性试验,构建橡胶隔振器的仿真模型,分析偏心式压力机冲击载荷下橡胶弹簧的变形和应力分布情况;研究正弦激励下橡胶隔振器的动态响应,探讨橡胶弹簧动刚度的变化规律;对比分析偏心式压力机安装橡胶隔振器前后对地面基础的冲击激励,得出橡胶弹簧的隔振效果。此研究成果为偏心式压力机的隔振技术研究及橡胶隔振器的设计研发提供了理论指导和技术支撑。
英文摘要:
      According to the vibration isolation problem of eccentric press,the combining methods of theoretical derivation,simulation analysis and experimental verification were adopted to study the dynamic load which was produced in the working process of eccentric press.Combined with the mechanical properties test of rubber material,the simulation model of rubber vibration isolation was built,the deformation and stress distribution of the rubber spring under the dynamic load of eccentric press were analyzed.The dynamic response of rubber isolator under sine excitation was studied.The dynamic rigidity changing rule of rubber spring was discussed.The incentive impacts to ground base before and after installation of rubber isolator in the working process of eccentric press were analyzed,and the vibration isolation effect of rubber isolator was drawn.As a result,the research result provides theoretical guidance and technical support for eccentric press vibration isolation technology and rubber vibration isolation design.
