摘要
由于重型机床结构件超大、地基基础结构复杂庞大以及受结合面和边界条件的精度影响,普通仿真计算环境已无法满足系统计算要求,为此首先推导了定量式静压导轨结合面接触模型,同时提出了边界条件有限元实现的方法,然后搭建了重型数控机床-地基基础系统的云计算仿真平台,最后基于云计算平台分析了不同因素对重型数控机床-地基基础系统承载变形的影响。结果表明:适当的夯实混凝土基础周边的土体或重新填充混凝土基础周边的土体可提高混凝土基础的承载变形能力;增加重型数控机床主要工作区的混凝土基础的宽度可提高混凝土基础的承载变形能力。
Owing to the size of the structural parts of most heavyduty machine tools, the complex structure of their foundations system, and affected by the joint surface and boundary conditions, the common simulation environments fail to meet the computational requirements. Firstly, the contact model of the static pressure guide was derived, and the realization of the boundary condition was presented. Then the cloud computing simulation platform of the heavy NC machine tool-foundation system was built. Finally, the influ-ence of different factors on bearing deformation was analyzed based on the cloud computing platform. The results show that increase strength of concrete foundation surrounding soil or refilling soil surrounding concrete foundation can improve the foundation bearing ca-pacity ;The bearing deformation of the concrete foundation can be improvedby change width of concrete foundationof the main work area.
