    • Abstract
  • As one part of double-layer non-linear vibration damping fastener, nylon locking sleeve can realize the pre-assembly of the fasteners by locking the upper and lower iron plates and the middle damping pad into one body, thereby greatly reducing the workload of on-site construction. According to the technical requirements, impact test should be carried out on the nylon locking sleeve after being manufactured. No damage should be left in the sleeve when it bears 6 shocks of 50 kg hammer falling freely form a height of 45 mm. In this paper, impact test tooling based on the technical requirements of nylon locking sleeve is designed, and the impulse response of the tooling computed by ANSYS. The structure is further optimized according to the calculation results, and the optimized structure can meet the strength requirements. The weight falls from 15.87 kg to 8.17 kg, which is convenient for the disassembly and assembly operations. The optimized impact tooling can meet the requirements of impact test.
