Claim 1:
2. A design method of a vibration isolation/damping satellite mount of a chopped carbon fiber reinforced thermoplastic composite material, comprising the following steps:
carrying out a standard tensile test of the composite material to obtain an elastic constant and Poisson's ratio of the chopped carbon fiber reinforced thermoplastic composite material;
creating a finite element analysis framework for a component made of the thermoplastic composite material, and performing a deformation analysis on different mount configuration under working condition load;
designing and establishing an optimization model according to load conditions in actual engineering conditions, and using a generalized algorithm in a topological optimization method to carry out optimization design of structural parts of the mount, establishing and solving an optimization mathematical model with minimum strain energy as an optimization objective and with mass and frequency as optimization constraints to determine a conceptual reference diagram;
on a basis of topological optimization, carrying out parametric modeling to obtain an optimal design of the structural parts; and
modifying a configuration of the component optimized in combination with a molding process to prepare the structural parts by injection molding.
