中文摘要:
      目的 针对常用四角衬垫的七自由度包装衬垫进行动力学分析,为以后用该类型衬垫仿真奠定基础。方法 使用Matlab进行编程产生随机高斯白噪声,并进行滤波处理,然后使用ode15s模块对以能量法建立七自由度的衬垫包装系统进行动力学微分方程求解。结果 各支脚的垂直振动位移趋势一致,且数值大小低于8 mm,偏转角位移介于0.006~0.008 rad之间,被包装物垂直位移响应低于6~6.8 mm,验证了在该工况下缓冲衬垫的缓冲特性。结论 在该激励作用和包装系统的减振作用下,被运输包装物得到了有效的防护,并且线性趋势和实测相吻合,仿真效果良好。
英文摘要:
      The work aims to conduct the kinetic analysis on the packaging pad with seven degrees of freedom with respect to the four-corner cushion to lay the foundation for the simulation with such kind of pad. Matlab was used for programming to generate random Gauss white noise, and the white noise was filtered. After that, the ode15s module was used to solve the dynamic differential equation of the pad packaging system with seven degrees of freedom based on energy method. The vertical vibration displacement of all legs was consistent, with the numerical value less than 8 mm, the deflection angle displacement between 0.006 and 0.008 rad and the vertical displacement response of the package lower than 6~6.8 mm. In such case, the cushioning characteristics of the cushioning pad were verified under this working condition. Under the action of such excitation and the vibration of packaging system, the transported package is effectively protected and the simulation results are achieved through the matching of the linear trend and the measured data.
