  • Addressing Complexity for Automotive Software and Systems Engineers
    Addressing complexity for automotive software and systems engineers – Today’s cars have about 30,000 parts and more than 100 million lines of code1 – To cope with rising product complexity and crushing amounts of data, teams must embrace the cloud to maintain a competitive edge – 47% of failed projects are due to poor requirements2 Three key areas are driving the digital transformation in automotive engineering Product complexity Data, data, data A connected, smart car is generating large amounts of data, while processing data from external sources such as weather and traffic. It’s not just interacting with other drivers, but also exchanging data with other connected devices such as smart phones, watches, connected homes, workplaces and other connected spaces. Today’s cars are required to have built-in data intake and processing capabilities, along with on-board analytics. Such data capabilities require advanced electronics and software, which in turn drives up product development complexity. More software than hardware Computerization of vehicles has been long underway, but the requirements for smart cars are a paradigm shift in how the products are designed and engineered. Today’s smart cars are packed with processing power which requires millions of lines of code to function properly. The situation is getting more complex as we head towards autonomous driving. A myriad of systems are being controlled by software, that haves to perform flawlessly while delivering a pleasurable occupant experience. As the complexity of product design increases, the reliance on modern engineering and development processes becomes increasingly crucial. Digitally managing requirements For an organization to be successful, it needs to deliver results.

  • What You Need to Know About Mounting Radial Tires on Classic Vehicle Rims
    What You Need to Know About Mounting Radial Tires on Classic Vehicle Rims Over the past 100 years, tires, and the wheels that support them, have gone through significant changes as a result of technical innovations in design, technology and materials. No single factor affects the handling and safety of a car’s ride more than the tire and the wheel it is mounted on and how the two work together as a unit. One nagging question that has been the subject of a lot of anecdotal evidence, speculation, and even more widespread rumor is whether rims designed for Bias ply tires can handle the stresses placed on them by Radial ply tires. And the answer is - it depends. It depends on how the rim was originally designed and built as well as whether the rim has few enough cycles on it, and how it has been driven. But most importantly it depends upon the construction of the tire and how it transmits the vehicle's load to where the rubber meets the road. In this paper, we want to educate you on the facts - not the wives tales or just plain bad information - about how Bias and Radial tires differ in working with the rim to provide a safe ride. Why is there a possible rim concern between Radial and Bias Tires? The fitting of radial tires, to wheels and rims originally designed for bias tires, is an application that may result in rim durability issues. Even same-sized bias and radial tires stress a rim differently, despite their nearly identical dimensions.

While you can’t put a value on saving a life, keep in mind that TPMS systems will carry a cost. The systems themselves are added into the price of the car. The batteries in the sensors will fail and parts will break over time and need to be replaced. In colder climates around Western NY, ice and salt are frequent causes of TPMS failures. In addition, there are other behind-the-scenes costs to be aware of. Every time a tire is replaced, repaired, rotated or balanced, the tire technician has to deal with the TPMS system.

  • Standards and Requirements for Scrap Tire Transporters
    Division of Materials and Waste Management December 2018 Guidance Document #640 Standards and Requirements for Scrap Tire Transporters Purpose This educational guideline addresses owner and operator responsibilities when registering and operating a scrap tire transportation business which either picks up tires in Ohio or delivers tires to an Ohio destination and is intended to guide readers through some of the major requirements of the scrap tire rules. However, it is only a guide and the appropriate sections of the Ohio Administrative Code should be read in their entirety. Applicable Rules and Statutes Ohio Revised Code 3734 Ohio Administrative Code 3745-27-54 through 3745-27-56 Who must register? Chapter 3734.83 of the Ohio Revised Code states that “….no person shall transport scrap tires anywhere in this state unless the business or governmental entity that employs the person first registers with and obtains a registration certificate from the director of environmental protection.” It should be noted that there are several exclusions from the requirement to become a registered scrap tire transporter which are outlined below. However, if a transporter does not meet one of the specific exclusions provided below, then registration with Ohio EPA is required. The requirement to become a registered scrap tire transporter is not required if any of the following apply: 1. If 10 or less scrap tires are transported per load; 2. If tires are transported only for the transporter’s own agricultural use or in producing or processing aggregates; 3. If the transporter is a solid waste hauler who transports 10 or fewer tires which are incidental to the solid waste load; 4.
