santa ana, ca--(marketwire – March 22, 2011) – msc software, the company leader in the supply of multidisciplinary solutions, ha annunciato oggi che l’università di washington a st. louis, il jet propulsion laboratory (jpl) e il massachusetts institute of technology (mit) hanno selezionato md adams to develop a dynamic model with multiple elements of the land survey medium called “opportunity” and to shape the interactions of that medium with the soil during the journey of realistic models of soil.
the model, called artemis, includes the representation of the stresses in the wheels due to the interaction of the same with the elements of the soil and with a deformable soil. The model of a single wheel has also been developed so as to understand in detail the interaction between wheel and ground, in order to simulate the complete six-wheel drive system and the complex independent suspension system. the model is currently being validated in the face of experimental data related to the single wheel and deriving from the project “mars yard”, using an engineering model of the medium that runs different types of terrain.
At the moment, the research team is reviewing the data related to opportunity, comparing them with the results of the model. These results include experiments related to the crossing of obstacles at the meridiani planum, in which the wheels are lowered by 5 cm with a sliding of 58%, the rise of hills on rocky soil finely covered by ground and the slip that occurs when the opportunity probe runs down a hill covered with earth. the goal is to obtain a valid model and able to simulate the driving of the vehicle on the unsigned and covered paths of land on which opportunity will be found when it reaches the edge of the ancient crater, 20 km wide. the edge has some rocks that are older than any other rock examined on the surface of the marten and the slopes, steep and covered with earth, will present with all probability different problems of mobility to the middle.
The mountain carlo approach will be used with md adams to simulate driving and route planning, so as to determine the less risky access points for the mission. the simulations will make available a new tool to select the driving directions that can minimize the chance to meet potentially dangerous conditions for opportunity.
prof. raymond arvidson, director of the laboratory “earth and planetary remote sensing” at the Washington university of st. louis stated, “md adams allowed us to quickly develop a complete dynamic model of the medium opportunity, including realistic interaction of wheels and soil. a totally dynamic approach is the only method able to allow the accurate modeling of the vehicle during the missions, since the vehicle has six independent wheels and a very complex suspension system that ensures that the actuators of the wheels interact in a non-intuitive way, so as to keep the vehicle on the predetermined trajectory. ”
“We are very proud to be part of such an innovative project as artemis,” said david yuen, sr. vp for commercial operations in the Americas ,msc software. “We are convinced that our software and know-how will contribute in a consistent way to the realization of opportunity. ”
raymond e. arvidson, ph.d.raymond ernst arvidson, ph.d. is an estimated university professor at the Washington University of st. louis. the professor obtained a doctorate at brown university and was author of several research projects related to planetary geology. at the moment, he directs the laboratory “earth and planetary remote sensing”, which is strongly involved in several substantial aspects of the planetary exploration projects of the nose, including the development of scientific plans and objectives for missions, participation in the missions themselves, data analysis and their storage and distribution with the aim of understanding and characterizing the planetary surfaces and depths. for more information, visit the sites http://wufs.wustl.edu/eprsl/ e http://pds-geosciences.wustl.edu/.
