基于有限元分析的制造业成本控制

Manufacturing Cost Control Based on Finite Element Analysis

针对零件设计阶段产品开发试制成本过高的问题,从有限元模型焊道连接角度分析其原因以降低成本。基于满足产品模态、动刚度及强度力学性能的前提下,利用模拟仿真计算的方法对焊道分布、焊道长度及焊接工艺进行优化。仿真分析表明,优化后的焊道的位置及焊接长度性能满足客户产品力学性能及工艺要求,可有效削减零件总成质量,降低公司的试制生产成本,为后续降低副车架的开发试制成本提供了新思路及成功案例,极大提升公司产品竞争力。

In view of the high cost of product development and trial production in the part design stage,the cost reduction was analyzed from the angle of finite element model weld bead connection,based on the premise of meeting the product modal,dynamic stiffness and strength mechanical properties,the distribution,length and welding process of weld bead were optimized by simulation calculation.Simulation analysis shows that the optimized weld bead position and welding length performance meet the mechanical properties and technological requirements of customers,which can effectively reduce the weight of parts assembly and the cost of trial production.It provides new ideas and successful cases for the subsequent development and trial production cost reduction of subframe,and greatly improves the competitiveness of the company's products.
