Abstract EN
Split torque designs can offer significant advantages over the traditional planetary designs for helicopter transmissions.
However, it has two unique properties, gap and phase differences, which result in the risk of unequal load sharing.
Various methods have been proposed to eliminate the effect of gap and promote load sharing to a certain extent.
In this paper, system design parameters will be optimized to change the phase difference, thereby further improving load sharing.
A nonlinear dynamic model is established to measure the load sharing with dynamic mesh forces quantitatively.
Afterwards, a multiobjective optimization of a reference split torque design is conducted with the promoting of load sharing property, lightweight, and safety considered as the objectives.
The load sharing property, which is measured by load sharing coefficient, is evaluated under multiple operating conditions with dynamic analysis method.
To solve the multiobjective model with NSGA-II, an improvement is done to overcome the problem of time consuming.
Finally, a satisfied optimal solution is picked up as the final design from the Pareto optimal front, which achieves improvements in all the three objectives compared with the reference design.
