查询词典 space rocket

To predict influence of the rocket acceleration force and vibration on electron cyclotron resonance thruster when it is being launched to space, a finite element model of 10 cm C/C composite material grid was established with finite element analysis software. Some of its dynamic characteristics, vibration response characteristics and models was analyzed.
