Vulnerability of Lunar Habitats and their Contents to Moonquakes

This video will propose a method to evaluate the vulnerability of essential components to the unknowns of the lunar seismic environment. It will also highlight the main differences between lunar seismic disturbances and the launch vibration environment. A case study is presented to illustrate the usage of the method.

Lunar structures will be exposed to one of the most extreme environments that have ever been considered for human settlements. In situ, regolith-based materials are being proposed for construction on the moon. The benefit is in reducing the cost of transporting large amounts of materials. However, the properties of materials that are made, all or in part, from indigenous lunar resources are lik...

Understanding the Lunar seismic environment is critical for establishing safe surface habitats to support a lasting human presence. Insight derived from the Apollo Passive Seismic experiment underscores the limited seismic data available about moonquakes, making the design of structures able to withstand those solicitations quite difficult. The goal of this research is to create a functional an...

In this video we share the approach we are taking in the RETH institute to establish the knowhow to design resilience extraterrestrial habitats. The entire team is involved in this effort to generate the tools and testbeds needed to assess the research outcomes. Our control-theoretic approach is intended to design habitats that are resilient to the wide variety of frequent disruptions that are ...

MCVT: Structural Mechanical Model

Просмотров 3463 года назад

This presentation will describe the structural mechanical model of the habitat in the MCVT, which simulates the structure's response under operational loads and external disturbances. The process and methods used to develop a physics-based model with damageable-repairable capabilities that can be executed in real-time will be discussed. An illustration of the implementation of the SMM within th...

The habitat internal environment model (HIEM) presentation will explain the modeling of pressure and temperature within the defined habitat space of the MCVT. The pressure distribution utilizes a zonal model approach that treats the air column as a series of fixed-volume finite elements whose mass changes based on changes in the system. The temperature distribution is determined using a similar...

MCVT: Human Model

Просмотров 533 года назад

This presentation describes the model used to capture the impact of human crew members modeled as a moving heat source within the habitat. The human model uses a daily schedule received from the crew and returns an amount of heat in real time corresponding to the activity being performed in each moment. With these disturbances, the interior habitat must then stabilize its temperature and mainta...
