Design And Experiment Of An Advanced Rocket’s Launch Pad

Launch pad is an important part to carrying the rocket ground equipment, before and between the rocket, it is vertical support the rocket; According to the requirements of rocket control system, adjust the verticality of the rocket; Coordinate with the aim of targeting equipment to complete and some rocket ancillary work. In the technology as the first productive forces of today, the rapid development of China’s aerospace industry, launching various tasks satellites, missiles and manned spacecraft more and more frequently, so the launch pad development work has growing importance.The development of this launcher has experienced the demonstration phase, phase of the program and the sample stage. Phase of the program, according to the product requirements of the mission statement, the mission statement for the characteristics of the product, and on how to achieve technical specifications and features of this product consult the relevant technical information at home and abroad, demonstrates a variety of technical solutions that can be achieved on the launch pad It should reach the main technical indicators and major technical measures to be taken were analyzed demonstration. On the basis of the principles of the demonstration program and to carry out research on comprehensive engineering design work. From structural design to analysis, calculation and implementation, from the interface to the consultation confirmed that the discussion will be refined to finalize the scheme design report, the ultimate expression of the design drawings.This paper begins with the development of the indicator of view, the launch Taichung several important parts, including the Taiwan body, reducer, leveling legs and the support devices, three-dimensional modeling using PRO / E, and the use of mechanical knowledge proof design rationality. Then the three-dimensional model design has been imported into the ANSYS finite element analysis, the stress and strain of cloud. Identify the structure of the stress concentration, focus on verifying the design of supporting device, adjustment device, retarder and etc, includes the calculation of gear transmission and worm transmission. But also on the support means, leveling spiral legs, the leveling legs reducer and the support were calculated design verification, specific to the helical cylindrical gears, worm gear calculations. ANSYS calculated according to calculation results and important components of mechanical systems launch pad stiffness and strength to meet the technical requirements. Finally, the prototype design was subjected to a series of essential test, there is the launch pad leveling test, functional test docking cylinders, leveling legs rain test, load test launch pad, the rocket body and vertical positioning test systems linked tone test. Through the analysis of test results, and technical deficiencies it found design flaws, to provide a guarantee for the development of the engineering prototype of the next round.
