Modeling the truck as a whole: Scania uses LMS Imagine.Lab Amesim for testing approach
SIEMENS – Just how do you design a truck?
And especially a truck that needs to haul loads of timber out of snowy Scandinavian forests or coal out of dusty, unpredictable Indonesian mines?
Or, simply be able to run dependably 24 hours a day, seven days a week on the highway?
Precision is the answer for Scania. Obtaining this precision equals the right type of design early in the process. This is just one of the reasons why this global truck manufacturer uses LMS Imagine.Lab™ software. The engineering team counts on this tool to simulate the entire vehicle dynamics, including the hydraulics and the driveline, and to couple various systems such as electronics to create a “virtual” truck.
A leader in the truck and bus market, the Swedish multinational was founded in 1891. Since then, the company has produced and delivered more than 1,400,000 trucks and buses for heavy transportation. You can imagine that a lot has changed since Gustaf Eriksson designed a usable petrol engine in 1902, the year the company manufactured its first truck. more> http://tinyurl.com/l3er3qc

Siemens – LMS controls engineering is an engineering discipline that deals with designing and implementing control systems to achieve a desired overall system behavior. It is the backbone of “smart” products. In its basic form, a control system lets you measure a performance factor in the product using sensors. Based on this measurement data, you can adjust the behavior of product to regulate the performance factor towards a desired objective.
The first step is to understand the requirements. You can design a control system that can meet multiple objectives, but it is important to understand the different objectives and the interactions. How fast should a product react to change in the system? What about a change in external conditions?
You need to get a big picture view. Some of the requirements could set performance goals, which have to be optimized, while others serve as constraints to be satisfied. Some of these requirements can be competing against each other and the design should carefully trade off between competing requirements.
Then we draw out a boundary diagram of the system architecture. What are the components of the system that can be measured by sensors, and which system properties can be changed by actuation to satisfy the requirements? At this point, we do a requirement feasibility analysis to see if the existing sensors and actuators can actually meet the system objectives. Such analysis is mostly done today using system simulation with computer models. Examining the analysis results, we can see if the conceptual system architecture is really possible. If yes, we start a detailed design.
We start by dividing the controller into units according to the required functions. When designing an engine control system, for example, we have to make sure that we are delivering the required torque. To do this, you design a torque management function that “measures” the torque demand through the driver accelerator pedal input. Then this is translated into appropriate airflow and spark-timing actuations to deliver the demanded torque at the engine crank shaft.
In parallel, you look at the fuel management function that seeks to minimize fuel consumption while delivering the required fuel to generate torque. The emission control and thermal management functions also impose constraints on how the airflow, spark timing and fuel system are actuated to ensure that exhaust emissions are minimized and the engine operates in an efficient temperature range. It is a bit like completing a 10,000 piece jigsaw puzzle.
To realize the control system within the overall architecture, we start to define the interfaces and populate the various system functions to fulfill requirements. Today, computer models of the controller units are built to virtualize the functions. The units and their interfaces are rendered graphically to assist the engineers in rapidly evolving design processes. In parallel, we design and implement test cases to make sure that the control system works and meets requirements. more> http://tinyurl.com/nme6utm

Shipbuilding industry at a crossroads
Siemens – On February 20, 2014, the Global Shipbuilding Executive Summit (GSES) members, which included more than 80 executives from government and industry from both the USA and Europe, focused on four areas:
- Pre-contract award process
- Design and engineering processes
- Shipyard productivity improvements
- Shipbuilding process improvements.
There were two groups of 10 members each that focused on developing a specific set of steps to improve each of the four focus areas over the next 15–18 months, including setting a set of goals for the next GSES in February 2015 and selecting an executive mentor to help guide each team. At the conclusion to the summit, the members voted on the top recommendations to pursue over the next 12 months. There were eight of them.
The top three recommendations were:
- Collaboratively develop requirements that are aligned with and consistent with budgets;
- Reduce uniqueness in future ship classes, i.e., common systems; and
- Optimize the material flow through shipyards.
The other five of the eight recommendations will be considered in the next phase of this long-term program between government and industry to improve shipbuilding productivity and lower the overall total ownership cost of future ship classes and fleets. Now, cross-functional teams are being formed to pursue each of the top three recommendations. They will meet monthly and have quarterly reviews with the mentors and a final progress report to GSES VI in February 2015.
The top priority for each recommendation is for the results of team research to have significant and measureable impact on the cost of future ship classes and to share these recommendations with shipbuilders around the world to improve shipbuilding productivity via technical papers, presentations and briefings. more> http://tinyurl.com/nmvn3ee

In simulation we trust
SIEMENS – Simulation technology has a lot to offer to mold manufacturing. It’s a matter of recognizing the problems that it can help to solve.
Beginning with NX™ version 8.5, state-of-the-art mold flow analysis technology has been added to NX ‘s powerful arsenal of validation tools. NX additionally includes data quality checking, molded part validation, interference/clearance analysis, tool kinematics simulation and cooling and strength analyses. The new mold flow analysis technology, EasyFill Analysis, integrates Moldex3D capabilities into NX to help designers save time setting up simulations, checking designs, and evaluating design alternatives.
NX Mold Design can include directly integrated mold flow simulation capabilities that help save time setting up simulations, checking designs and evaluating design alternatives. more> http://tinyurl.com/pkl2y3k
Curtiss-Wright continuously improves electronics production processes
SIEMENS – Consumers all over the world have more product choices than ever before. Electronics manufacturers and suppliers are under tremendous pressure to deliver innovative, high-quality products and components as efficiently as possible while adhering to industry standards.
However, what should they look for in a product lifecycle management (PLM) and digital manufacturing (DM) solution? What are the essentials needed to achieve excellence in electronics manufacturing?
Curtiss-Wright Controls Embedded Computing designs and manufactures rugged circuit card assemblies for the military commercial off-the-shelf (COTS) market.

By Tony Christian – PLM really started life as technology to help major engineering firms (especially auto companies) to manage the large variety of electronic product information that was being produced by their CAD systems at the design stage.
Now, the ambition for PLM is to extend its reach in the other direction – at the front end of the overall product lifecycle back as far as the initial innovation stage. PLM has been very successful in managing design in a controlled environment, but the initial idea creation phase requires support for free-flowing interaction and selection of winning options for development based on informed decision making. Manufacturers in multi-product, multi-industry businesses will have a huge range of potential development projects. So, before the design effort starts in earnest – the classic starting point for PLM – there is a major exercise in the selection of the projects to pursue. more> http://tinyurl.com/k9q5aph
