In this work, we tentatively assign the charmed mesons $D_{J}(2580)$,$D_{J}^{*}(2650)$, $D_{J}(2740)$, $D_{J}^{*}(2760)$, $D_{J}(3000)$ and$D_{J}^{*}(3000)$ observed by the LHCb collaboration according to theirspin-parity and masses, then study their strong decays to the ground statecharmed mesons plus light pseudoscalar mesons with the $^{3}P_{0}$ model.According to these study, we assigned the $D_{J}^{*}(2760)$ as the$1D\frac{5}{2}3^{-}$ state, the $D_{J}^{*}(3000)$ as the $1F\frac{5}{2}2^{+}$or $1F\frac{7}{2}4^{+}$ state, the $D_{J}(3000)$ as the $1F\frac{7}{2}3^{+}$ or$2P\frac{1}{2}1^{+}$ state in the $D$ meson family. As a byproduct, we alsostudy the strong decays of $2P\frac{1}{2}0^{+}$,$2P\frac{3}{2}2^{+}$,$3S\frac{1}{2}1^{-}$, $3S\frac{1}{2}0^{-}$ etc, states, which will be helpfulto further experimentally study mixings of these $D$ mesons.
