| 摘 要： | 本文对CJ83-50kJ液压模锻锤进行了锤击前的动力分析,给出了计算锤击前锤头和锤身的加速度和速度公式,并用Matlab编写程序求解出了锤击前锤头的加速度;在碰撞过程、能量分配和打击效率的研究基础上,建立了CJ83-50kJ液压模锻锤的双自由度有阻尼振动力学模型,并采用Irahim法对液压模锻锤的物理参数进行识别;根据液压模锻锤的振动力学模型,建立了仿真模型,并在不同的打击能量下,模拟了基础振动的加速度和速度,得到了加速度和速度随时间的衰减情况,并对出现这种情况进行了分析。

| Abstract: | Dynamical analysis of the CJ83-50kJ Hydro-pneumatic Forging Hammer before beating has been done in the text. The formulations to calculate the acceleration and velocity of the hammerhead and the hammer-body have been given out and the acceleration value of the hammerhead has been gained by using the Matlab programming method. A calculation model for CJ83-50kJ hydro-pneumatic forging hammer foundation vibration system with dual-freedom has been established on research of the process of beating, the distribut... |
