摘要
为解决多种轻量化材料在车身(BIW)上应用带来的复杂装配问题,引入复杂性理论描述多材料车身装配的复杂性,进行基于复杂性分析的多材料车身装配任务分配。依据车身装配操作中复杂性的来源,进行车身装配操作选择复杂性和装配操作执行复杂性的分类描述与度量,并建立基于复杂性分析的装配任务分配优化模型,算法求解得到装配系统复杂性最小的任务分配优化。实例验证了基于复杂性分析的装配任务分配的可行性,为研究基于复杂性分析的智能制造装配系统优化提供依据。
To solve the complex assembly problem caused by multiple lightweight materials used in car body-in-white(BIW),a complexity theory is introduced to describe the assembly operation complexity of multi-material car body.A model of assembly task planning is established for multi-material BIW assembly based on the assembly operation complexity metrics,taking complexity of the assembly operations as an indicator of tasks assignment.A door assembly is taken as an example of algorithm optimization solution to obtain the minimum complexity.To verify validity of the assignment based on complexity,it is compared with task allocation on the assembly node time.This also provides an indication to further studies on the optimization of a multi-parameter system.
