Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears [PDF]
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile

Calculation and Analysis of Modified Gear Time-varying Meshing Stiffness based on Matlab
Jixie chuandong, 2022 Considering the real involute and transition curve equation of gears，an accurate model of gears is conducted. The deformation of modified gear is deduced and calculated by Weber energy method. The mapping relationships of load angle βj，pressure angle αk，rotation angle tan αk and coordinate XMj of load point are deduced.
