Model-based systems engineering tackles product complexity

Automotive and off-highway were the first industries forced by the mechatronics revolution to move their engineering practices out of habits rooted in 1950s-era product architectures, into 21st-century methods grounded in simulation-led, systems-driven product development. Today’s smart, connected, self-aware and situationally aware cars, trucks and agricultural and construction equipment—managed by ultra-sophisticated onboard mechatronic systems-of-systems—are almost as far advanced from earlier-generation mechanical devices governed by primitive electromechanical (if that) control systems as relativity and quantum mechanics were from the classical physics of Newton and Maxwell. Products of that complexity simply can’t be successfully developed, integrated and validated using last-century tools and methods that leave discovery and remediation of system-level design flaws until detail design or even, disastrously, delivery to market.

PTC, ANSYS to develop platform solution enabling digital simulation for the Industrial IoT

PTC and ANSYS partnered to accelerate the industry-wide move to bring engineering modeling and simulation to the Industrial IoT.

Just before the start of LiveWorx 2017, PTC’s annual mega-event around all things IIoT, the two leaders agreed to develop a solution that will let ANSYS engineering simulation technology be rapidly added to applications built on the ThingWorx Industrial IoT platform from PTC. Development of a connector between these two technology platforms will let customers transform raw data into new forms of actionable intelligence, the companies said. The connector will integrate intelligent digital simulation models with products as they exist and operate in the real world, the companies explained. The aim is to open up new opportunities for companies to create value by enabling them to optimize operations and maintenance and to integrate them into their product development processes.

Looking forward in software development: An interview with MSC Software VP of Product Development Doug Neill

Doug Neill is an expert in the aerospace industry, and a recognized, respected voice in the engineering community. He is best known for his work on multidisciplinary design optimization (MDO) technologies in the aerospace industry, and for his involvement with various organizations such as AIAA (the American Institute for Aeronautics and Astronautics), where he was a leading member of the MDO technical committee for two tours across seven years.

After joining MSC Software, Doug became the company’s representative on the Aerospace Flutter Dynamics Council (AFDC), a private technical committee focused on aeroelastic simulation methods for the aerospace industry. MSC is the only software vendor that is a permanent invited member of that committee, because of MSC’s expertise in, and early and ongoing commercial support of, the relevant technologies. From all his experiences—beginning as a technical contributor, researcher and aerospace engineer, to his management of contracts, aerospace vertical applications, Nastran products and now MSC’s product development organization—Doug has a developed a unique philosophical outlook on leadership.

CosiMate from Chiastek: Co-simulation conduit for multifidelity systems modeling

How to efficiently and effectively co-simulate whole-product functional systems models that include component subsystem models at differing levels of abstraction, or fidelity, has long vexed product engineering teams and simulation technology providers alike. Now, a powerful, elegant solution to this obstacle to faster, more efficient and effective model-based systems engineering (MBSE) is available in CosiMate, the core software product from Chiastek.

This tremendously exciting new technology breaks through what has long stood as one of the worst obstacles to implementing truly production-level MBSE: the difficulty of co-simulating whole-product functional systems models whose component subsystem models are at varying levels of fidelity. As they almost invariably are. Continue reading

Water pump design: Geometry optimization for a shrouded impeller

For CFD-driven shape optimization of water pumps with shrouded impellers, it’s essential to have an efficient variable-geometry model defined by a set of relevant parameters (design variables). This case-study example focuses on geometry modeling of a typical water pump, with the goal of attaining maximum flexibility in shape variation and fine-tuning.

To begin, the geometry was set up in CAESES (CAE System Empowering Simulation), the software platform from FRIENDSHIP SYSTEMS that helps engineers design optimal flow-exposed products. CAESES provides simulation-ready parametric CAD for complex free-form surfaces, and targets CFD-driven design processes. Its specialized geometry models are ideally suited to automated design exploration and shape optimization. Continue reading

Frustum Generate topology optimization plus 3D Systems DMP expertise slash weight of GE Aircraft bracket 70%

A perennial engineering challenge is designing a part to meet performance requirements while observing design constraints imposed by manufacturing processes. Conventional subtractive machining offers sharply limited ability to cost-effectively produce complex geometries, especially biomorphic shapes and lattice structures. The result of those manufacturing limitations is often components and products with suboptimal functionality and performance.

But today, with advances in 3D printing and especially direct metal printing (DMP) swiftly making these technologies more and more available and effective, many constraints imposed by traditional manufacturing processes are going away. At the same time, software technologies for multidisciplinary design exploration are emerging to help engineering and manufacturing organizations make the most of these new production processes. In particular, rapid advances in topology optimization technology are helping engineers generate the most efficient designs for single-step manufacture by latest-generation DMP systems. With this combination of new technologies, what the engineer designs is essentially what gets manufactured, with very little of the time- and labor-intensive manufacturing engineering that before now was needed to turn engineering intent into machinable reality.

The business value of this confluence of new technologies was dramatically proven in a recent project by software developer Frustum and 3D Systems’ Quickparts on-demand parts service. The project was part of a public challenge to industry by GE Aircraft to reduce the weight of an aircraft bracket while maintaining the strength needed to meet all of its functional requirements, primarily supporting the weight of the cowling while the engine is in service.
