The Damping Base And Ballistic Design For The Rocket Sled Test Of Strap-down Inertial Navigation System

Adopt rocket sled test method for Strap-down Inertial Navigation System check on function, first assured trap-down Inertial Navigation System for lash vibration not greater than reality condition. Next, for the rocket sled length defined, must contented trap-down Inertial Navigation System function check of azimuth accelerated speed and last times demand. At present, the two studying aspects be blank, it need settled must, for guarantee rocket sled test of trap-down Inertial Navigation System check on function efficacious works.This text be directed against for how reduce Strap-down Inertial Navigation System's lash vibration carry on deep into studying of rocker sled., for applied low open damp vibrating isolation principle, and composite vibrating isolation method, completed Strap-down Inertial Navigation System's install table, apply simulated analyses method for install table vibrating isolation potency analyses and examined. Other, on the basis of Strap-down Inertial Navigation System check of function pathway parameter and totacity test designed, combined solid explosive rocket of test and brake recover technology, completed the pathway design, result of the pathway calculate results contented require.Be means of 2 shot test, the measurement results indicated it makes Strap-down Inertial Navigation System come under vebranting overloading lower 3go; adopting different mldel flow profiles as bound and rationally setting water skid, it satisfies ballistic demand:the biggest speed more than 300m/s, holding the course overloading of 12go～18go over 1.5s and the most negative overloading is lower 13go. Though testing verification, the design of installing damping platform and ballistic setting for Strap-down Inertial Navigation System can satisfy tests, and these technology designing is feasible.
