“…Finite Element Method (FEM) can be used to simulate rolling and sliding contact, and considerably precise stress results are expected. The worst load condition is often regarded as the condition wherein one pair of teeth carries the full load, and the position in the area around the pitch point of a single teeth pair engagement is simulated with the maximum value of contact pressure [4].…”

“…Extensive studies have focused on the LTCA of helical gears with FEM, and significant progresses have been made. Qin [17] and Gurumani and Shanmugam [10] developed a 3D helical gear FEM with the addition of computer-aided design (CAD) software and imported it into a finite element solver for static simulation. Contact load distribution and contact stress are also calculated to analyze the crowning effects.…”

In order to perform a tooth contact analysis of helical gears with satisfactory accuracy and computational time consuming, a parameterized approach to establish a high-precision three-dimension (3D) finite element model (FEM) of involute helical gears is proposed. The enveloping theory and dentiform normal method are applied to deduce the mathematical representations of the root transit curve as well as the tooth profile of the external gear in the transverse plane based on the manufacturing process. A bottom-up modelling method is applied to build the FEM of the helical gear directly without the intervention of CAD software or creating the geometry model in advance. Local refinement methodology of the hexahedral element has been developed to improve the mesh quality and accuracy. A computer program is developed to establish 3D helical gear FEM with contact region well refined with any parameters and mesh density automatically. The comparison of tooth contact analysis between the coarse-mesh model and local refinement model demonstrates that the present method can efficiently improve the simulation accuracy while greatly reduce the computing cost. Using the proposed model, the tooth load sharing ratio, static transmission error, meshing stiffness, root bending stress, and contact stress of the helical gear are obtained based on the quasistatic load tooth contact analysis. This methodology can also be used to create other types of involute gears, such as high contact ratio gear, involute helical gears with crossed axes, or spiral bevel gears.

“…Kawalec et al presented a comparative analysis of tooth-root strength evaluation methods used within ISO and AGMA standards and verifying them with developed models and simulations using the finite element method [22]. Therefore, finite element analysis (FEA), which can involve complicated tooth geometry, is now a popular and powerful analysis tool to determine tooth deflections and stress distributions [23][24][25][26].…”
