Simultaneous Optimization of Variable Blank Holder Force Trajectory and Tools Motion in Deep Drawing via Sequential Approximate Optimization

Analysis of Optimization of Blank Holding Force In Deep Drawing By Using LS DYNA

Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Cup drawings involves many parameters like punch and die radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for cup drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can...

Sequential Approximate Optimization Using Variable Fidelityresponse Surface

Adaptive Probabilistic Trajectory Optimization via Efficient Approximate Inference

Robotic systems must be able to quickly and robustly make decisions when op-erating in uncertain and dynamic environments. While Reinforcement Learning(RL) can be used to compute optimal policies with little prior knowledge about theenvironment, it suffers from slow convergence. An alternative approach is ModelPredictive Control (MPC), which optimizes policies quickly, but also ...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Optimization of parameters of Anti lock Braking System for use in deep drawing

A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...
