Although they hold much promise, this has not exactly been a stellar time lately for self-driving/autonomous vehicles. As a matter of fact, recent events have cast a dark cloud over them.
Testing them on the road is, of course, essential, but I’ve often wondered if digital simulation could be used more to maximize safety and efficiency with less road testing required.
As it turns out, this very thing, simulation, is finally being performed quite extensively.
This week, Siemens introduced a breakthrough solution for the development of autonomous driving systems as an addition its Simcenter portfolio that minimizes the need for extensive physical prototyping while dramatically reducing the number of logged test miles necessary to demonstrate the safety of autonomous vehicles.
In a nutshell, this computing and simulation platform is aimed at accelerating the validation and verification of autonomous cars.
Siemens PLM Software Driving Simulator
According to the findings of a report issued by the Rand Corporation, autonomous vehicle prototypes would have to be driven hundreds of millions of miles, and in some cases hundreds of billions of miles, over the course of several decades to demonstrate their reliability in terms of fatalities and injuries – an outcome the authors deemed inconsistent with the near-term commercial viability of self-driving cars. For possible solutions to these challenges, the researchers pointed to innovative testing methods such as advanced simulation technologies.
Leveraging advanced, physics-based simulation and innovative sensor data processing technologies, the new Siemens solution is designed to help automakers and their suppliers address this industry challenge with the potential to shave years off the development, verification and validation of self-driving cars.
This week, PTC announced Creo 5.0, the latest release of its Creo CAD software that covers concept to manufacturing in a single design environment. According to the company, Creo 5.0 introduces five new and enhanced capabilities for product design and productivity enhancements in the areas of topology optimization, additive and subtractive manufacturing, computational fluid dynamics, and CAM.
“PTC is on the leading edge of some of the hottest technologies today with the Internet of Things (IoT) and augmented reality (AR), but it has not forgotten its roots in CAD, instead transforming this business by infusing its leading Creo software with new technologies and capabilities,” said John Mackrell, chairman, CIMdata.
The physical design of products is often limited by existing designs and practices. The new Creo Topology Optimization Extension automatically creates optimized designs based on a defined set of objectives and constraints, and freed of existing designs and thought processes. This helps users save time and accelerate development by enabling creation of optimized parts for given tasks they must perform.
Creo automatically creates optimized geometric forms/shapes based on input conditions and defined criteria.
The Creo Topology Optimization Extension will be available Summer 2018 in the first maintenance build of Creo 5.0. (more…)
Recently, ANSYS, known for its engineering simulation software, and MachineWorks known for its machining and verification software signed an agreement to expand the use of Polygonica Polygon Modeling Software toolkit throughout the ANSYS organization.
Polygonicais a polygonal solid modeling toolkit for processing polygon mesh and is the creator of MachineWorks.
Polygonica carries out a wide range of geometric operations on polygon mesh models such as automatic solid healing, fixing self-intersections and Boolean operations. Other algorithms in Polygonica allow remeshing, simplification, offsetting and point cloud manipulation.
Polygonica is built on MachineWorks’ core technology for material removal and machine simulation, and has a wide range of applications for many sectors, including additive manufacturing/3D printing, where solving complex polygon modeling problems is required when handling defective models with vast numbers of polygons.
Polygonica is used in ANSYS Discovery Live software, ANSYS’ relatively new tool that enables fast computation of CAE analysis results using the power of local GPUs. ANSYS Discovery Live shortens the feedback loop between design and analysis and lets product designers see relevant results immediately during the conceptual design process.
Interview with ANSYS at IMTS 2016
Even though we’ve been told by a number of software vendors for several years now to use engineering simulation and analysis at the earliest stages of product development, relatively few companies have heeded the advice and actually done so. In many cases, it’s still design, break, repeat in a cycle that gets very expensive quickly trying to achieve optimized design goals. Even with all the insistence and chiding from the simulation folks, I’d estimate the percentage of design work that includes simulation early in the process as somewhere between 20-25%, although that may be a bit on the high side.
With ANSYS Discovery Live, ANSYS hopes it will break and change that cycle.
3D printing, or more accurately, additive manufacturing (AM), has come a long way since its inception, and especially the past few years. It also continues to grow at an amazing rate. IDC forecasts worldwide spending on 3D printing to be early $12 billion in 2018
A new update to the Worldwide Semiannual 3D Printing Spending Guide from International Data Corporation (IDC) shows global spending on 3D printing (including hardware, materials, software, and services) will be nearly $12.0 billion in 2018, an increase of 19.9% over 2017. By 2021, IDC expects worldwide spending to be nearly $20.0 billion with a five-year compound annual growth rate (CAGR) of 20.5%.
Discrete manufacturing will be the dominant industry for 3D printing, delivering more than half of all worldwide spending throughout the 2017-2021 forecast. Healthcare providers will be the second largest industry with a spending total of nearly $1.3 billion in 2018, followed by education ($974 million) and consumer ($831 million). By 2021, IDC expects professional services and retail to move ahead of the consumer segment. The industries that will see the fastest growth in 3D printing spending over the five-year forecast are the resource industries and healthcare.
The leading use cases for 3D printing are prototypes, aftermarket parts, and parts for new products. As the primary use cases for the discrete manufacturing industry, these three use cases will account for 44% of worldwide spending in 2018.
As testament to this tremendous growth, this week, 3D printer manufacturer Ultimaker announced that Robert Bosch GmbH, a leading global supplier of technology and services, will invest in Ultimaker 3 Extended printers on a global scale. After comparing several desktop 3D printers, the additive manufacturing department of Bosch selected Ultimaker as the most reliable, easy-to-use, and machine that produced the highest quality parts. The printers will now be used in different locations across Germany, Hungary, China, India, the United States and Mexico for printing innovative prototypes, tooling, jigs and fixtures, while cutting design and manufacturing costs.
Ultimaker Interview at Westec 2017
As the world’s largest supplier of automotive components and an important supplier of industrial technologies, consumer goods, and energy and building technology, Bosch, has a strategic objective to deliver innovative products. In order to save time and costs, and for a faster time-to-market for its new products, the company decided to invest in desktop 3D printing on a global scale. Now, with the Ultimaker rollout, all departments of the additive manufacturing department of Bosch can benefit from a uniform 3D printing solution with materials, training and global support. This approach will ensure consistent, quality 3D printing results across teams and locations.
In the cloud-based technical/engineering platform world, IoT may be getting the lion’s share of attention at the moment, but right up there competing for relevance and significance are VR/AR technologies. As cool as they are, VR/AR technologies have been hindered from wider use primarily because of the expensive high GPU requirements needed to make them work, and well, be realistic. That’s changing, however, as cloud-based platforms bring performance and fidelity to VR/AR at much lower entry and implementation price points.
Case in point, this week a Detroit-based startup, ONU, announced a unique offering called ONU 3DLite, a cloud-based 3D visual platform designed to convert and optimize CAD files for creating visual content for 3D Web, AR, VR, or mobile-based applications. ONU provides technology to streamline 3D asset creation pipelines, automating processes that have been manual. In other words, an end-to-end, 3D asset management platform.
“Manufacturers design products in CAD, but those files don’t easily translate to visuals that can be displayed on a mobile device, let alone in a web browser, virtual reality headset, or augmented reality glasses,” said Sam Sesti, President of ONU. “ONU 3DLite changes that. Our easy to use tools automate processes that were previously manual, and significantly streamlines 3D asset creation. Native CAD files can be turned into low polygon Filmbox (FBX) files in just minutes. In addition to making asset creation really easy, it’s also very affordable. We’re excited to share ONU 3DLite with the world.” (more…)
