Nonlinear energy trap device capable of realizing any-order rigidity and energy collection
The invention relates to a non-linear energy trap device capable of achieving any-order rigidity and energy collection. The non-linear energy trap device comprises a mechanical spring unit, a mass block, a friction sliding rail, a pulley, a non-linear shape rail, a constraint baffle, a bottom plate and an electric power storage unit. Dowel bars are arranged on the two sides of the mass block and connected with the pulleys, and the mass block is in sliding fit with the friction sliding rails and rubs against the friction sliding rails. Left and right and front and back pairs of constraint baffles are arranged; nonlinear tracks are arranged on the two sides of the mass block, the curved surface sides of the nonlinear tracks make contact with the pulleys, the plane sides of the nonlinear tracks are connected with the left or right constraint baffles attached with the piezoelectric patches through mechanical spring units, and the front and rear ends of the nonlinear tracks are in sliding fit with the constraint baffles on the front and rear sides; the electric power storage unit is electrically connected with the piezoelectric plate. The non-linear energy trap device can realize any-order rigidity and energy collection, and for different vibration control targets, the optimal vibration control effect can be achieved by optimizing the non-linear restoring force through structure adjustment.
