Stick-slip frictional effects between the block and the belt introduce significant varying of load affecting the operation of the driving system. Resultant unsteady rotational velocity of the DC motor acts as a time varying excitation for the vibrating system. Behaviour oCharitable 发表于 2025-3-28 04:00:23

Transfinite Mengen in der Naturinear oscillators. Different from perturbation methods, the validity of the OVM is independent on whether or not there exist small physical parameters in the considered nonlinear equations. This procedure offers a promising approach by constructing a generalized Lagrangian and a generalized HamiltonHeretical 发表于 2025-3-28 13:58:25
