Dökme Demirden Hidrolik Valf Plakasının Topoloji Optimizasyonu için Level Set ve SIMP Yöntemlerinin Karşılaştırmalı Analizi

Öz

Hafif ve yüksek verimli bileşenlere yönelik artan taleple birlikte, bu çalışmada dökme demir hidrolik valf plakası için SIMP ve Level Set topoloji optimizasyon yöntemleri karşılaştırılmaktadır. Her iki yaklaşım da mekanik dayanımı koruyarak yaklaşık %35 oranında ağırlık azaltımı sağlamıştır. Ancak Level Set yöntemi, döküme uygun pürüzsüz geometrileri daha az yinelemeyle üreterek hesaplama açısından üstünlük sağlamıştır. SIMP istikrarlı bir yakınsama sunsa da, üretilebilirliği sağlamak için ek geometrik iyileştirmeye ihtiyaç duymuştur. Bu bulgular, modern yapısal optimizasyon gereksinimlerini karşılamada her bir yöntemin göreceli avantajlarını ortaya koymaktadır.

Comparative Analysis of Level Set and SIMP Methods for Topology Optimization of a Cast Iron Hydraulic Valve Plate

Öz

Driven by the increasing demand for lightweight and high-efficiency components, this study compares SIMP and Level Set topology optimization methods for a cast iron hydraulic valve endplate. Both approaches achieved approximately a 35% mass reduction while preserving mechanical strength. However, the Level Set method proved computationally superior, requiring fewer iterations to yield smooth, cast-ready geometries. Although SIMP offered stable convergence, it necessitated additional geometric refinement to ensure manufacturability. These findings outline the relative advantages of each method in fulfilling modern structural optimization requirements.
