Abstract
To investigate the effects of different solar array configurations and layouts on the impact resistance of lunar landers,multibody dynamics simulations were performed using commercial software to analyze the landing shock response characteristics of four typical configurations(deployable top-mounted,deployable peripheral,fixed top-mounted,and fixed peripheral)under four-leg synchronous landing conditions.The dynamic response of impact loads and bending moments at key joints was compared among the configurations.The results showed that the peak moments of deployable solar arrays were significantly higher than those of fixed ones,owing to the flexibility of the deployment mechanisms and assembly clearances.The multi-point connections in peripheral layouts effectively dispersed the impact loads and reduced the impact amplitudes at the joints.The landing impact energy was mainly distributed in the frequency range of 128-158 Hz.Therefore,the fixed peripheral layout is recommended for lunar lander solar array design,and special attention should be paid to avoid the hazardous frequency band of 120-160 Hz.These findings provide a reference for the configuration selection,layout optimization,and ground impact testing of lunar lander solar arrays.关键词
