ANALYSIS OF VIBRATION LOADS TO SPACE MANIPULATION SYSTEM BY THE CARRIER ROCKET

С. В. Исаенко

Abstract


One of the categories of ensuring robot reliability - mechanical strength. The robot must be resistant to a variety of impacts, aimed at its destruction, for example any emergency situation or inadvertent influence of the person. In case of space robotic systems also need to sustain the severe vibration stresses arising at launch and landing. One way to check robot to withstand vibration stresses - testing on a vibration table. However, breakage during vibration testing requires considerable time and financial expenses for redesign the robot, restoration of damaged parts and re-testing. This can be avoided by pre-conducting vibration simulation. Modeling identifies the most vulnerable in the mechanical sense of detail and allows engineers the opportunity to make timely changes to the project. This report highlight the work of the vibration simulation of space manipulation system, show the results of calculations, schedules and distribution charts of surface stresses. Vibrational modeling is an important condition for creating high-quality products and can save considerable resources in development and manufacturing of systems for space purposes. Development of methods for evaluation of vibration disturbances on products designed to operate in space is of great interest for the creators of such technology.
