Abstract:
Dynamics and vibroacoustics of mechanical transmissions are perceived as one of the major concerns in the contemporary geared driveline design. These characteristics influence durability and efficiency of the system, as well as its quality. However, due to strong local effects and system nonlinearities, computer analyses of gears can be extremely time consuming, and hence, in the industrial practice, are carried out only to some limited extent. This paper describes a time-efficient multibody approach to this problem, which allows for fast analyses of high fidelity, complex numerical gearbox models. The approach presented in the paper consists of two phases: firstly, static transmission error curves, describing the gear meshing stiffness, are derived by analyzing high fidelity Finite Element models of the gears; subsequently, time-efficient multibody simulations of gear dynamics under different operating conditions are achieved by using a specifically defined user force element that allows to take the meshing stiffness variability into account thanks to the previously calculated static transmission curves.
