This SAE Standard applies to directional drilling electronics and tracking equipment of the following types: - Tracking Transmitter - Tracking Receiver - Telemetry Device - Remote Display This type of tracking equipment is typically used with Horizontal Earthboring Machines as defined in SAE J2022.
This SAE standard applies to all electric battery-powered machines that fall within the scope of SAE J2130. Purpose To define a uniform method of determining the time a battery-powered machine will continue operating normally with a given set of batteries.
The electric vehicle industry - land, water and air - is rapidly rising to become a market of over $533 billion by 2025. Some run entirely on harvested energy as with solar lake boats. Others recycle energy as with regenerative braking of cars, buses and military vehicles harvesting kinetic energy. Others use different forms of harvesting either to charge the traction batteries, or to drive autonomous device. In some cases, harvesting is making completely new forms of electric vehicle possible such as "glider" Autonomous Underwater Vehicles (AUVs) that can stay at sea for years, gaining electricity from both wave power and sunshine. Multiple forms of energy harvesting on one vehicle are becoming more common from cars to superyachts.
Since the last edition of this report in 2013, the demand on automakers has been relentless in terms of improving fuel economy and reducing emissions, thus driving increased sales of forced induction systems. The use of pressure charging techniques has therefore expanded significantly. Recent years have seen the ascendancy of the turbocharger and its use by almost every major global manufacturer.
Off-highway CVTs A continuously variable transmission can improve the fuel efficiency of heavy-duty diesels by matching the engine's torque/speed to the applied load through the smooth torque multiplication of the transmission. Hydraulics for economics The design of a digitally controlled hydraulic fan drive from Denison Hydraulics is said to help diesel engines run leaner and cleaner. Telematics boosts productivity Advances in electronic technology enables equipment owners and operators to monitor not only usage, but location of equipment. A dumper on tracks Industrial vehicles featuring composite rubber-tracked drive systems have become increasingly popular over the past 10 years, carving out a respectable niche in many specialized industries.
This SAE Recommended Practice provides general guidelines for measuring the splash and spray produced by vehicles operating over wet pavements. The guidelines describe both the video digitizing and the laser methods of analysis. The video-digitizing method uses video images and contrast measurements between black and white checkerboards when a spray cloud is superimposed on them as a means of measuring the obscuring spray. The laser method uses laser transmittance through the spray cloud as the means of measurement. It is left to the users of this practice to decide which method is best suited to their needs. There is no implied relationship between these two methods, although it is expected that the ranking of relative spray reduction between test vehicle configurations would be approximately the same. All sections listed in this document are to be considered as common to both methods, unless otherwise noted.
This SAE Recommended Practice describes the test procedures for conducting frontal impact restraint system tests for heavy truck applications. Its purpose is to establish recommended test procedures that will standardize restraint system testing for heavy trucks. Descriptions of the test set-up, test instrumentation, photographic/video coverage, and the test fixtures are included.
This SAE Recommended Practice describes the test procedures for conducting frontal impact restraint component tests for heavy truck applications. Its purpose is to establish recommended test procedures that will standardize restraint system testing for heavy trucks.
