What is the advantage of topology optimization?
Benefits of topology optimization A shortened design process: Topology optimization can drastically reduce product development timelines — which translates to reduced costs. The automated process generally leads to better-performing parts in much less time than would be needed for traditional design methods.
How does topology optimization work?
In simple terms, topology optimisation takes a 3D model and creates a design space. It then removes or displaces material within it to make the design more efficient. While carrying out the material distribution, the objective function does not take aesthetics or the ease of manufacturing into account.
What is compliance in topology optimization?
In mechanics, “compliance” roughly stands for the inverse of “stiffness”. To improve the structural integrity you may often want to minimize the strains in the structure which means minimizing the compliance or maximizing the stiffness.
What is density based topology optimization?
The density based topology optimization procedure represented by the SIMP (Solid isotropic material with penalization) method is the most common technique to solve material distribution optimization problems. The choice of the initial guess demonstrated to be a determining factor in the final topologies obtained.
What is topology optimization and why is it useful?
Topology optimization takes a 3D design space and literally whittles away material within it to achieve the most efficient design. The method doesn’t care about aesthetics, traditional approaches, or any other of the usual design constraints that you would normally use in design.
What is the difference between topology optimization and generative design?
Topology optimization takes a 3D design space and whittles away material within it to achieve the most efficient design. Generative design is a way to autonomously generate optimal designs from a set of system design requirements.
How long does topology optimization work?
It can build an optimal shape in about 60 seconds. Unlike most optimization techniques, topology optimization utilizes a level-set‒based method, meaning that a precise smooth shape is defined at each step of the process.
What is weighted compliance?
2 – Weighted Compliance is just a combination of Compliance values for multiple loadcases. So, WCOMP = Sum(wi * Ci) wi is a weight scale factor. Ci is the compliance of each loacase ‘i’ So, if you have 10 static loadcases in your model, you can combine them using WCOMP.
When was topology optimization first used?
The origins of topology optimization, date back to the late 1980s. That’s when the idea of leveraging computing power to speed the development of structures that are optimized for characteristics such as mass and stiffness first emerged in the world of academia.
Is solidworks generative design?
The new Topology Study in SOLIDWORKS® Simulation enables you to quickly and easily optimize shapes from the start of your design work—resulting in lighter, higher–quality parts that are fit for manufacturing.
What is topology optimization in additive manufacturing?
Topology optimization is an optimization method that employs mathematical tools to optimize material distribution in a part to be designed. Earlier developments of topology optimization considered conventional manufacturing techniques that have limitations in producing complex geometries.
What is Simp method?
The most popular mathematical method for topology optimization is the Solid Isotropic Material with Penalization method (SIMP). The SIMP method predicts an optimal material distribution within a given design space, for given load cases, boundary conditions, manufacturing constraints, and performance requirements.
