“…It is difficult, however, to find a strong enough actuator for generating a large enough contact force. 14 Recently, a hybrid momentum exchange impact damper that uses actuators in combination with passive elements was suggested. 15 The damper, which is called an active-passive hybrid MEID (HMEID), was applied for reducing the shock responses of a landing spacecraft.…”

A shock load occurred in a short time duration can lead to dangerous effect on the machine or structure. The use of conventional technique for shock vibration control by modifying the systems damping reduces the steady-state response of the system. However, this method fails to attenuate a large acceleration peak at the moment after the shock. An alternative method for reducing the maximum acceleration peak due to shock load using the principle of momentum exchange has been developed. When the shock excitation frequency is much larger in comparison with the main mass natural frequency, the passive momentum exchange impact damper(PMEID) produces good performance. However, the performance of PMEID decreases as the shock excitation frequency close to the main mass natural frequency. In this research, a simple technique to improve the performance of PMEID utilizing the pre-straining spring mechanism (PSMEID) is proposed. The dynamic model of the system with PSMEID is derived. Next, the simulation is conducted to evaluate the effectiveness of the proposed method.

Finally, the hybrid MEID (HMEID) mechanism, which combines the PMEID and AMEID mechanisms, was introduced to reduce the need to set appropriate parameters in PMEIDs and to reduce the large power requirements of actuators in AMEIDs [8].…”

Several mechanisms have been proposed to solve shock response control problems in vehicle engineering. The momentum exchange impact damper (MEID) mechanism has been considered for solving shock response control problems in spacecraft landing systems. The effectiveness of MEIDs against the shock responses of a running cart collision problem was investigated using simulation. A novel hybrid MEID mechanism is proposed by considering the time-difference operation of both passive and active MEIDs to optimize the actuator parameters. In this time-difference hybrid MEID (TDHMEID), the amount of passive momentum exchange can be easily identified. Therefore, TDHMEID can be used to set the optimal parameters for active actuator operation. The effectiveness of the TDHMEID mechanism on controlling the shock response and saving actuator energy is verified by simulation. ARTICLE HISTORY

“…Hara et al reported a landing method that used a momentum-exchange impact damper (MEID). [4][5][6][7][8][9][10] This method realizes a soft landing by controlling the momentum of a spacecraft by launching damper masses. To increase the momentum exchange efficiency, Kushida et al proposed an active/passive hybrid MEID (HMEID), 7) which uses both active and passive elements for the mass launch.…”

In future surveys, planetary exploration spacecraft will need to land on rock beds and slopes. Therefore, spacecraft should be equipped with landing methods to facilitate soft landings in these severe regions. However, conventional landing methods have problems such as high rebound, the impossibility of reuse, and excessive resource consumption. To overcome these problems, the authors previously invented several landing methods, but these have practical limitations. Thus, this paper proposes a novel landing mechanism called the base-extension separation mechanism (BESM), which focuses on energy conversion using springs and separable units, and discusses a single-axis falling-type small-scale model of a spacecraft with the BESM. Then, the rebound and acceleration suppression performance is evaluated through simulations. These reveal that the BESM realizes good performance under nominal conditions. The BESM is shown to have good robustness against variations in the ground stiffness, ground damping, spacecraft mass, and installed mass. The study findings reveal that the BESM is a promising method: it overcomes the drawbacks of the conventional methods and our previous inventions. In addition, the BESM generally performs better in soft landings than our previous inventions.
