| 摘 要： | 从土体粘弹塑性理论出发,使用阻尼、弹性、塑性3元件的组合反映土体应力应变特性,由此建立冲击夯与土体系统的动力学模型和相应的运动微分方程组。通过编制相应的MATLAB程序,可以得到振动冲击夯工作的实时数据,为振动冲击夯的设计和优化提供了新的途径。

| Abstract: | Based on the viscoelastic-plastic theory of soil body.the tress—strain characteristics of soil body is reflected by the combination which consists of damping,elastic and plastic components.Then the dynamic model and equation set of impact tammer-soil body system is built.After computer programming,the real-time working data of impact rammer is obtained and a new method for optimal design ofimpact rammer is provided. |
