作者 张振林 王玉峰 《河南科技》 2016年第5期69-70,共2页
针对现有轴承磨床工件箱角度调整不准确,且调整时间太长的问题,将原调整机构改为丝杠丝母调整结构,改进回转轴结构,不仅能够满足精确、快速调整的要求,并且可以实现长期的精度保持,实现无间隙调整,提高了机床的工作效率。

Complementing our previous publications, this paper presents the information schema constructs (ISCs) that underpin the programming of specific system manifestation feature (SMF) orientated information management and composing system models. First, we briefly present (1) the general process of pre-embodiment design with SMFs, (2) the procedures of creating genotypes and phenotypes of SMFs, (3) the specific procedure of instantiation of phenotypes of SMFs, and (4) the procedure of system model management and processing. Then, the chunks of information needed for instantiation of phenotypes of SMFs are discussed, and the ISCs designed for instantiation presented. Afterwards, the information management aspects of system modeling are addressed. Methodologically, system modeling involves (1) placement of phenotypes of SMF in the modeling space, (2) combining them towards the desired architecture and operation, (3) assigning values to the parameters and checking the satisfac- tion of constraints, and (4) storing the system model in the SMFs-based warehouse database. The final objective of the reported research is to develop an SMFs-based toolbox to support modeling of cyber-physical systems (CPSs). 展开更多
