This paper presents a review of literature for a terramechanics experimentation capability for the U.S. Army Tank Automotive Research, Development, and Engineering Center (TARDEC) in Warren, Michigan. Despite the increasingly important role that light-weight and small ground vehicles play in combat and military operations, most researchers do not currently have the ability to (i) measure vehicl...

Soil compactibility which basically depends on soil texture, organic matter and soil water content during farm machinery traf®cking are major factors affecting soil conservation. In a ®eld experiment, cattle farmyard manure was applied to a silty clay loam soil (®ne-loamy, mixed, thermic Typic Haplargids, USDA; Calcaric Cambisols, FAO) in Isfahan, Iran. Three rates, 0, 50, 100 Mg haÿ1 (on oven ...

Planetary rovers are different from conventional terrestrial vehicles in many respects, making it necessary to investigate the terramechanics with a particular focus on them, which is a hot research topic at the budding stage. Predicting the wheel–soil interaction performance from the knowledge of terramechanics is of great importance to the mechanical design/evaluation/optimization, dynamics s...

ABSTRAKHambatan merupakan aspek penting yang perlu diperhatikan dalam mendesain sebuah kapal. Salah satu upaya untuk mengurangi hambatan adalah memodifikasi bentuk haluan kapal dengan menggunakan Ulstein X-Bow. Penelitian ini bertujuan mengetahui efektifitas penggunaan X-Bow serta mencari nilai hambatan, trim dan sinkage terkecil metode CFD (Computational Fluid Dynamics) teknik overset mesh. Pe...

Wind propulsion is envisioned as one of the solutions for decarbonisation maritime transport, it offers high efficiency in terms primary energy comsumption. Many wind systems already exist at various development stages, but uncertainties over their performance a strong obstacle to adoption by ship owners. This paper presents general method assessment steady and unsteady performances wind- prope...

Introduction: Curiosity has been traversing across the northern plains of Gale Crater since August 2012 and on 1/6/17 (Sol 1571) has traveled over ~15 km (based on wheel odometry). The rover is approaching a prominent hematite-bearing ridge, which it will ascend to make measurements, thereafter continuing south up the slopes of Mount Sharp. Curiosity has already encountered multiple mobility is...

Abstract The paper is concerned with a node-based, gradient-driven, continuous adjoint two-phase flow procedure to optimize the shapes of free-floating vessels and discusses three topics. First, we aim convey that elements Cahn–Hilliard formulation should augment frequently employed Volume-of-Fluid model maintain dual consistency. It seen such consistency serves as basis for robust primal/adjoi...
