Abstract: The spring dampers for remote weapon station have large stiffness and small damping that leads to low firing dispersion and poor reliability. A viscoelastic elastomer damper suitable for remote weapon station was developed. A viscoelastic elastomer material with good viscosity-temperature characteristic was prepareded based on the existing viscoelastic elastomer material. A viscoelastic elastomer damper prototype was designed on the basis of the property and structure parameters of spring damper for remote weapon station. The mechanical properties of the viscoelastic elastomer damper prototype and the spring damper were compared and studied through the static pressure test and the drop weight test. In order to reduce recoil stroke, a new viscoelastic elastomer damper was designed without changing the external dimensions and structure. The mechanical properties and the firing frequency adaptabilities of the new viscoelastic elastomer damper were studied through the static pressure test and the firing frequency simulation test. The test results indicate that the compounded viscoelastic elastomer material has a strong viscosity-temperature characteristic; the energy absorptivity of the viscoelastic elastomer damper prototype is 1.47 times more than that of spring damper, and there is no secondary impact effect; the energy absorptivity of the new viscoelastic elastomer damper is 77.28%, and its maximum stroke is 7 mm, which has good firing frequency adaptability. The viscoelastic elastomer damper is able to effectively reduce the recoil stroke and increase the energy absorptivity, thus improving the firing dispersion and reliability of remote weapon station.
