Multibody Dynamics Integrated with Simulation Process and Data Management

  Today, manufacturing firms are avoiding iterative and costly physical testing processes by implementing CAE tools into their engineering cycle. They only produce few or sometimes no prototypes at all and they easily test the products’ durability, noise and vibration harshness (NVH), computational fluid dynamics (CFD), and morewith these tools during the design process. Particularly …

Adams Car Integration with Simulation Process and Data Management (SPDM)

To avoid iterative tests and multiple design changes to physical prototypes, engineers today use simulation software. Adams Car is a system dynamics solution that allows car manufacturers to build and test functional virtual prototypes of the complete vehicle under various road conditions and design changes. Adams Car’s architecture is based on databases of CDBs, which …

Finding the Solution to a Noise Problem

A nighttime noise complaint was issued from the residential area near one of Wärtsiläs main large 4-stroke medium speed engine factories located in downtown Vaasa.  The facility produces about 500 engines per year and every engine is subjected to a test run. An investigation found that the likely source of the intolerable noise was from the exhaust from an engine 1000 hour endurance test. Although they discovered the source of the noise, they were unable to solve the noise problem completely.

Case Study: Predicting Virtual Allowables

During the process of designing lightweight CFRP structures, one usually needs access to allowable values. However, allowables generation is particularly costly and time-consuming. Each characterized material system must cover various layups, coupon tests, and environment conditions. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property. With advanced …

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 …

Next-Generation Materials Lifecycle Management for Additive Manufacturing

  Using a Next-Generation Materials Lifecycle Management System to Address Process Issues with Additive Manufacturing     Some of the challenges faced by companies involved in additive manufacturing include the lack of a central repository where materials attributes are stored, high scrap rates, and a lack of process repeatability. However, MSC Software’s Materials Lifecycle Management …
