Safety Performance Analysis Of A Launch Box (storage) Transport

The thesis is based on the research of new type launching canister of storage and transport, use the finite element theory and contact dynamics theory as the method to analyze the vibration of the launcher tube and the rocket during the stage of being impacted by the gas exhaust and being lifted transporting.The main content of the thesis is below.Firstly, discussed the main performance parameter and the composition of the rocket, the launching canister of storage and transport. The thesis used the finite element analysis theory as the fundamental method and used the multi-body dynamics as the assistant method. Established the simplified solid model, came up with the mesh principle of how to mesh the solid model of the launching canister of storage and transport and the rocket.Established the simulation dynamics model of coupling of canister and the rocket. Came up with the method to establish the precise dynamics model of contact between rocket bourrelet, spin knob, lock mechanism and the launcher tube.Secondly, according to the different motion characteristic of the rocket and influence factor on different working condition, researched the definition of the contact between the launcher tube and spin knob, lock mechanism,the definition of tangential and normal behavior of the contact surface.Came up with the applied range of penalty function method.Analyzed the solving and applying characteristic of explicit-analysis method.Used the theories mentioned above, ascertain the boundary condition of the finite element problem of the canister lifted process and impacted by the exhaust process.Lastly, according to the effect of thrust eccentricity of rocket and the extra acceleration caused by the rough road,analyzed the dynamic respond on different working condition.
