We describe a new implementation of the quasiparticle random-phase approximation (QRPA) in axially symmetric deformed nuclei with Skyrme and volume-pairing energy-density functionals. After using a variety of tests to demonstrate the accuracy of the code in {sup 24,26}Mg and {sup 16}O, we report the first fully self-consistent application of the Skyrme QRPA to a heavy deformed nucleus, calculating strength distributions for several K{sup {pi}}in {sup 172}Yb. We present energy-weighted sums, properties of {gamma}-vibrational and low-energy K{sup {pi}=}0{sup +} states, and the complete isovector E1 strength function. The QRPA calculation reproduces the properties of the low-lying 2{sup +} states as well or better than it typically does in spherical nuclei.
