Abstract In the planetary automatic transmission design, efficiency is one of the primary performance indicators determining the final selection from multiple candidates. However, efficiency evaluation is the last step of conceptual design, thereby causing the trial result is often known at the end of the design. A new methodology based on geometry is presented for multistage planetary automatic transmission design, ranging from clutching sequence synthesis to efficiency evaluation. The emphasis is placed on a unified model for design steps with different analysis principles to predict power transfer characteristics earlier. Some new results and improvements are also presented, such as general speed ratio change law, simultaneous traversal of different shift types, and the efficiency formula. An example is provided to illustrate the applicability to a 3-DOF planetary automatic transmission and shows that early identification of power transfer characteristics can lock in necessary subsequent calculations, thereby eliminating unnecessary analysis and speeding up the design process.

Nowadays, inductive wireless power transfer is widely used in various applications over a large power range. However, for high power systems, testing the magnetic coupler implementation often requires too much time, space, and expense for normal laboratory conditions. For such a reason, a miniaturized system is a viable alternative to the actual system for a preliminary test of transfer characteristics and control strategy before constructing the full-scaled system. This paper studies the scale conversion rules required for miniaturized coupler design to ensure the scaled and original systems are as equivalent as possible to each other in terms of transfer characteristics. To verify the proposed theory, a 1:15 scaled magnetic coupler was constructed, and its transfer characteristics were compared with the original system. The proposed scaling rules were tested by experiment, and the results agree well with the theoretical analysis and simulation.
