Degraded visual environments (DVEs) pose significant safety and efficiency problems in military ground vehicle operations. As part of a larger research program, two field tests were conducted to evaluate driving aids while indirect driving in DVEs. The current paper presents the results of one of these field tests, and focuses on the challenges and lessons learned in designing a challenging test course and producing consistent dust clouds for assessing Soldier driving performance and workload in degraded visual environments.

Railway ballast dynamic stability operations is an important work in the line maintenance and repair operations, the selection of dynamic parameter is usually dependent on field trials and practical experience, for lack of theoretical basis. This paper creates discrete element analysis model of railway ballast using the discrete element method, the numerical simulations are carried out to study the lateral ballast resistance during dynamic stability process. We focus on the influence of vibration frequency during dynamic stability process; an optimal vibration frequency of the simulation analysis is obtained and compared with the recommended vibration frequency of a product of a China Railway Large Maintenance Machinery Company, it is found that the two vibration frequencies are basically consistent. This result verifies the correct validity of the discrete element analysis model of railway ballast during dynamic stability process.
