“…Analysis of crankshafts is also widely carried out in the literature. Rodrigues et al [17] presented the modal analysis of a six-cylinder crankshaft using both numerical and experimental approaches. Based on the resulted mode shapes and natural frequencies, damping factors were estimated to be used in dynamic analysis.…”

“…Assim, a matriz de amortecimento é definida separadamente através da curva de Rayleigh [(JUNIOR, 2011)]. Esta análise dinâmica foi resolvida no software AVL Excite Power Unit, onde foi possível ler o comportamento dinâmico do virabrequim condensado, por exemplo, forças, deslocamentos, momentos, aceleração quando em operação no motor.…”

“…De acordo com a referência (AVL, 2011B), para traçar a curva de Rayleigh, os pares de valores de ω e ξ recomendados para virabrequins são a primeira frequência natural com ξ = 0, 03 e 1000 Hz com ξ = 0, 05. O estudo experimental realizado por (RODRIGUES et al, 2011) mostrou que a resposta dinâmica do virabrequim é pouco sensível à variação do amortecimento de Rayleigh. Baseado neste estudo, nas análises transientes deste trabalho foi considerada a curva de Rayleigh da Figura 8.2.…”
