电除尘器本体结构优化设计是一个规模大,设计变量数多而具有相当难度的几何可调和拓扑可调优化设计问题。对这样一个大型复杂的结构优化问题,本文在文[1]的工作基础上,充分利用结构的力学特性,应用有效设计变量的概念,建立了不用求偏导数且不必解线性规划的可行方向法—KFD方法。该方法具有收敛速度快、占用内存少的优点,比通常ε有效约束可行方向法提高速度数十倍。实际应用的结果表明文中的方法是很有效的。
The structural optimization design of electrostatic precipitator body is a large-scale design problem with a large number of design variables and considerable difficulties in geometrical adjustment and topology-adjustable optimization. For such a large and complex structural optimization problem, based on the work of [1], this paper fully utilizes the mechanical properties of the structure, applies the concept of effective design variables, and establishes a feasible direction method that does not require partial derivatives and does not require linear programming. - KFD method. This method has the advantages of fast convergence speed and low memory consumption, which is tens of times faster than the usual ε effective constrained feasible direction method. The practical application results show that the method in this paper is very effective.
