“…Generally, the transfer of energy from the main mass to damper mass is maximum when time duration of the excitation force equals the contact time between the main mass and damper mass. 13 If a shock load works in a long time period, then contact force amplitude between the main mass and damper mass decreases, and a little strain energy stored is in the contact spring. Hence, the energy transfer using the momentum exchange mechanism becomes smaller, and the PMEID's performance decreases.…”

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.

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

When a spacecraft lands, the large shock load can lead to undesirable responses, such as rebound and trip. The authors have previously discussed the problem of controlling these shock responses using momentum exchange impact dampers (MEIDs). However, the optimal design parameters of MEIDs for spacecraft landing have not yet been addressed. These parameters are crucial for MEID applications. This paper discusses the parameters of Passive-MEID (PMEID) for a single-axis falling-type problem, which is the most fundamental problem. It is found that the rebound height is proportional to the mechanical energy of the spacecraft. Thus, the optimal design parameters of the PMEID correspond to the parameters that minimize the mechanical energy. A PMEID with the optimal design parameters is called optimal PMEID in this paper. In order to improve the performance of the optimal PMEID, this paper proposes a novel MEID -HMEID (active/passive-hybrid-MEID). The HMEID combines actuators with passive elements such as contact springs. Based on the optimal design results for the MEIDs, this paper applies a stiffness control to the HMEID in order to suppress the mechanical energy further. Simulation studies reveal that the HMEID can effectively reduce the influence of shock responses. The robustness of the HMEID against the landing ground is shown. The feasibility of the HMEID is also discussed. The HMEID is superior to a PMEID, even if the actuator has a dynamics with a large electric time constant.
