The performance of an Electric Vehicle Power Unit is directly connected with critical tolerances. Tolerances drive opportunities for performance enhancement with cost reduction. The tests normally used to determine and validate tolerances are both expensive and time consuming with prototype parts. By replacing the initial tests with Digital Twin simulations, results can be obtained quickly, and at a much lower cost. This article discusses one of these tests and the results.
Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes
Variable loads resulting from a working process, starting process, or operation near a critical speed will cause varying stresses at the gear teeth of a drive system. The magnitude and frequency of these loads depend upon the driven machine, the motor, the dynamic mass elastic properties of the system, and other effects.
How can the protective layer be applied to the brake disk more quickly and more effectively? And how can it be made to stay on for longer? “The solution is intelligent coatings, as can be applied to brake disks using our AM coating system” says Dr. Géza Koscsák - the head of additive mat the Chiron Group. He has played a prominent role in developing the new system and reaching the decision to opt for the high-speed deposition welding process in his previous job as head of advanced development.
GWJ Technology GmbH presents the new version of its system calculation software SystemManager as an extension of its well-known solutions eAssistant as a web solution and TBK as a classic desktop application.
Electric vehicles could represent up to 70% of all cars by 2050. To ensure the acceptance of their vibrational and acoustical characteristics, profound NVH analysis is the key to minimize vehicle excitations caused by specific e-drive transmission designs.
