Abstract

Digital prototyping is an innovative design method. With digital product prototyping techniques that are designed with the concept of Generative Design and Topology Optimization, the designer able to visualize and simulate the product start from the design, stress analysis to the product manufacturing process. The aim of this research is to optimization the topology of the product model results of generative design, determine the strength of the model through Stress Analysis used topology optimization 50%, 60%, and 70% of the product model results of generative design and figure the results of the product 3D printing in made prototype models as a result of generative design. This research is conducted in 3 steps, that is the preparation of made models with computing Autodesk Inventor Professional 2020, the analysis with generative design, and the printed with 3D printing. This 3D printed product is made in 2 models. Model 1 with a material reduction of 70% topology optimization was better than 50% or 60% material lighting. Model 2, the maximum of 50% Von Mises Stress reduction is smaller than the 60% and 70% reduction.Keywords: Digital prototyping, generative design, topology optimization

Abstract

Heat Exhanger Service Unit H101/08490 P.A Hilton Ltd that use for heat transfer experiment has a weakness because the water flow from the unit after taking heat will directly enter the storage tank, still have a high temperature  ( >33oC ). The use of practicum equipment for a experiment with a long enough duration will cause the cooling water are used have a high temperature and be ineffective for the heat exchanger cooling process. The purpose of making a Cooling Tower Type Heat Dissipator Model for Heat Exhanger Service Unit H101/08490  P.A Hilton Ltd so that the cooling water used to carry out the practicum will be maintained at a temperature of 28oC-33oC. Maintaining the stability of the cooling water temperature is expected to produce data that does not vary too much and can be done in a fairly long data collection range. The results of the performance and effectiveness test of cooling tower cooling show that the temperature increase is only 4oC for 3 hours of testing and the cooling effectiveness increases and is relatively constant during the test time. This shows that the cooling system with a cooling tower can be used as a supporting medium for heat exchanger practicum in the Mechanical Engineering department.
