Reducing the Product Development Time of a Rotary Cutter System Through Simulation

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.

Where’s the Dirt? – Use Realistic Material Loads in Adams

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.

Multibody Dynamics – Acoustics Integration

Even though multibody dynamics and structural dynamics are strongly coupled, acoustic radiation usually must be done in a different environment and the data must be converted to it. While converting the data by itself consumes time and requires manual work, engineers that deal with design production are usually not acoustic specialists. Hence, manual data transfer ...

Use of Multidiscipline Solutions to Improve Automotive Noise, Vibration and Harshness

Simulation software is being used extensively around the world due to their accuracy and cost-effectiveness. Instead of using different simulation tools for every different type of testing process, engineers can use multidiscipline tools to better improve NVH (noise, vibration, harshness). MD solution tools can be used for many different areas of testing, including:  Analysis of ...

Reducing Automotive Engine Noise with Multidiscipline Simulation

While companies can solve automotive engine noise problems by using engine mounts to stop vibration and the firewall to stop airborne noise, these solutions are not sustainable if one wishes to maintain quality. Therefore, car manufacturers taking advantage of finite element analysis (FEA) software to better understand noise and vibration. FEA can be used to ...

Identifying and addressing vibration issues early in the design process

A universal problem when optimizing noise and vibration is that it often conflicts with durability or cost. Multi-body dynamics helps balance these competing requirements early in the design process by addressing key vibration issues facing engineers, such as “will excitations in one part of the systems interaction with another part of the system?” MBD makes ...
