In this final blog of our Adams-EDEM co-simulation series, Darren Simoni from DSIM Technologies explains how EDEM and Adams have been used during the design of a skid-steer loader to increase the accuracy of system level simulation using less time and effort than traditional load estimation methods.
Today's vehicle and powertrain engineers face increasing challenges to meet fuel economy and drive quality targets, while at the same time keep vehicle cost reasonable. Many of the new engine technologies designed to improve fuel economy create difficulties for the noise, vibration, and harshness (NVH) engineer, whose job it is to assure a certain level of comfort for the occupants.
In my previous blogs I introduced the Adams-EDEM coupling, and explained how it works. In this post I want to share with you two examples of the Adams-EDEM coupling in action!
In my previous blog post I introduced the Adams-EDEM coupling that allows engineers to realistically simulate how bulk materials interact with their systems dynamics. In this post I want to give some insight on the workflow needed to use the coupling.
In the agricultural and heavy machinery industries, durability and strength are some of the most important indicators of quality. Maintaining high levels in these areas requires the application of many different tests and assessments to the end product. However, one of the most time-consuming parts of the production is the lengthy process of building physical prototypes, testing them for durability, then redesigning several parts and starting all over again. This process can significantly extend the time it takes to get a product to market. This was the case for John Deere Welland Works while developing a 20-foot rotary cutter system.
The world of heavy equipment is full of big machinery digging and moving dirt. Millions of tons of bulk material are moved every day by excavators, bull dozers, ploughs and trucks. The challenge faced by engineers who are designing such equipment is to understand how their machines will perform in the material environment they operate in.
