Laboratory-Scale Distributed Pressure Measurements of Blade Interaction with JSC-1A Lunar Simulant

摘要: AbstractBecause of the requirement for high reliability and very low weight, extraterrestrial excavator blade design in situ resource utilization (ISRU) must be more precise than current terrestrial practice. Three-dimensional finite-element discrete-element models should employed to enhance precision designs. These require that pressure distribution across known; however, this information is not available literature. To provide information, project measured on a suite laboratory-scale blades. The constructed model blades, designed implemented distributed total load measurements, developed soil preparation techniques, distributions errors, created empirical models. include: an array point pressures, quadratic function, exponential function. work concluded V-shaped with tapere...
