release device, simulated landing surface and ground measurement subsystem, as
shown in Fig. 15.11.
1. Test Model Subsystem of the Lunar Lander
In order to acquire real landing impact response of the lunar lander, it was necessary
to simulate the force transfer path and the force state of the lunar lander during
soft landing. Therefore, the main structure and landing gears of the lunar lander test
model was real, while other instrument could be structural analog model.
2. Lift, Release and Separation Device
For the lunar lander to get the energy during soft landing, the lunar lander test model
should be lifted to predefined height by lift, release and separation device. After the
initial parameters were setup, the release and separation device was started. The lunar
