In the planetary gear system with a gear ratio (NR/NS) set to 2 for Simscape, and following the equation Tr + Ts = Tc.
values were assigned to Tr and Ts.
When Tr is given twice the value of Ts, Tc comes out as Ts + Tr as expected.
The issue arises when Tr is not given twice the value of Ts.
In fact, Tc shows a value greater than Ts + Tr.
For example, while Ts(300) + Tr(600) = Tc(900) holds true, Ts(300) + Tr(500) = Tc(750) is observed.
- 1. Why does doubling Tr with 2Ts result in the correct value, and not doing so leads to an increase in the value?
- 2. Moreover, where does the value of 50 come from among the added values?
(Inertia of 10kg*m^2 is assigned to inertia2,4. In the planetary gear, inertia is in the 'off' state.)

안녕하세요
Simulation Initialization에서 initial value를 확인해 보시기 바랍니다. 에너지 평형을 찾는 과정에서 파라미터의 우선순위에 따라서 솔버가 찾은 해를 확인해 보실 수 있으며 필요에 따라 파라미터의 우선순위를 조정하여 해를 안정화 하거나 목표값을 달리할 수 있습니다. 참고하시기 바랍니다.

안녕하세요
Planetary gear는 조합에 따라 다양한 형태의 기능을 보여줍니다. 다양한 조합이 가능하지만, 한가지 예를 들어보면, Carrier - 고정 / Ring Gear - 입력 / Sun Gear - 출력 으로 하면 기어에 맞는 결과를 얻을 수 있습니다.
