Mg Concepts for the Vehicle Structure
DLR and Meridian technologies (link) developed a lower middle range car Front End Carrier (FEC) with topology optimization. Methodology-wise, it is interesting that they utilised predefined forces applied to spring elements in order to obtain a realistic force distribution, instead of … Continue reading

Gear shifter Housing and Contact Benchmarks
In the thesis study by Naresh Kalidindi and Mohamad Fardmoshiri (link) of Jönköping Institute of Technology, a magnesium gear shifter housing of a VW group car was optimized. Due to the die draw direction imposed most of the structure remained … Continue reading

Detection of Planar Regions in Volume Data for Topology Optimization
In this great work by Ulrich Bauer and Konrad Polthier (link) from Freie Universität Berlin, a method for determining planar regions in topology optimization results is developed. The results look very promising. Such a tool is very important for the … Continue reading
Non-Line-of-Sight Cannon (NLOS-C) Turret Saddle
Non-Line-of-Sight Cannon (NLOS-C) Turret Saddle was topology optimized by BAE (link). Maybe I am being a bit too negative nowadays but it is hard to see decently optimized structures. This one is not different too. Lets continue with pictures from … Continue reading

Heidenreich & Harbeck
Heidenreich & Harbeck applies topology optimization (link) to a slide for a high-speed milling machine to be cross-accelerated with 2 g. The structures topology was manually altered (we cannot call a manual trial and error study as optimization, as far … Continue reading

SA-SIMP
N. P. Garcia-Lopez et al. developed “An improved hybrid topology optimization approach coupling Simulated Annealing and SIMP (SA-SIMP)” (link). The topologies found by SA-SIMP method are reported to have round %6 higher rigidity than SIMP topologies and there are no … Continue reading
Pininfarina bonnet
I came across this article (link) by Pininfaria about the optimization of a car bonnet. The car is Argento Vivo concept, which seems to be very beautiful, made for Honda but unfortunately was not produced. However the optimization is not … Continue reading
Beam Structure Optimization for Additive Manufacturing based on Principal Stress Lines
Yongqiang Li, Yong Chen of Epstein Department of Industrial and Systems Engineering, University of Southern California, have developed a novel way of topology optimization for truss structures (link). The method relies on determining principle stress lines and forming a truss … Continue reading

ELEMENT EXCHANGE METHOD
ELEMENT EXCHANGE METHOD studied by Mohammad Rouhi is a non-gradient based method (link). It relies on exchanging lowest and highest strain energy elements, thus step by step reaching convergence. In the thesis it is shown that the method finds similar solutions … Continue reading
