| 摘 要： | 根据高速闭式曲柄压力机结构特点,建立了两自由度动力学模型.通过理论计算,确定了JF75G-125A型压力机的隔振参数.在ANSYS中进行隐式分析,利用拉杆预压缩方法施加机身预紧载荷;在LS-DYNA中进行预紧状态下显式动力学分析.有限元仿真结果表明,设计的隔振器参数能有效减小工作力引起的压力机对基础的冲击作用.

| Abstract: | Based on the structure characteristics of the high-speed closed crank press,a two-degree-of-freedom dynamics mode has been established.The parameters of vibration isolation for JF75G-125A press have been figured out by theoretical calculation.Implicit analysis has been conducted in ANSYS for application of pretension loading, and explicit dynamic analysis of the pre-tighten status has been achieved in LS-DYNA.Result of simulation indicates that the designed parameters of vibration isolation are effective on eliminating the shock and force transmission from the machine to the base. |
