A method is presented to find these stretchy members and calculate their length in folded state . the result of the geometric analysis of the model made in my lab is presented . the impact response produced by the tension springs in the diagonal members is very serious and a stowing mechanism is designed for the control of the impact 由于可展天線結(jié)構(gòu)展開動力來源于對角桿中拉伸彈簧,所以結(jié)構(gòu)在展開過程中沖擊力比較大,為了控制其展開速度,同時為了完成天線的收攏過程,需要電機(jī)來進(jìn)行控制,本文提供了一種電機(jī)控制機(jī)構(gòu)的設(shè)計方案。
