RISModeling and Calibration of a Structured-light Optical CMM via Skewed Frame Representation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new tetrahedron-target-based approach is presented for the extrinsic calibration of a non-contact “light-striping” (structured light) optical coordinate measuring machine (CMM). The procedure makes ...
Road Domain Near-Surface Wind Movement Characteristics in Sandy Area
Publisher: American Society of Civil Engineers
Abstract: Wind is the main factor that affects soil erosion and the severity of wind-sand disasters. Therefore, it is of critical importance to analyze the influence of remodeling topography units on the near-surface wind conditions ...
Abnormal Detection of Wind Turbine Operating Conditions Based on State Curves
Publisher: American Society of Civil Engineers
Abstract: Wind energy is a clean and renewable energy source and thus has promising future prospects. To increase the utilization rate and power generation of wind turbines and reduce their maintenance costs, it is necessary to ...
Novel Integrated Active and Passive Control of Fluid-Borne Noise in Hydraulic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid-borne noise (FBN) is a major contributor to structure-borne noise (SBN) and air-borne noise (ABN) in hydraulic fluid power systems and could lead to increased fatigue in system components. FBN is caused by the unsteady ...
Three-Dimensional Nonlinear Strength Model of Soil Considering Tenso–Shear Coupling
Publisher: ASCE
Abstract: Focusing mainly on the compressive-shear (C-S) stress, the existing soil strength theories fail to well describe the soil strength under tenso–shear (T-S) stress and are not suitable for analyzing the tensile strength and ...
An Excitation Trajectory for Dynamic Parameter Identification of Robot Using Logistic Function and Depth-First Search
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic parameter identification is playing an important role in robot dynamic controller design. However, many excitation trajectories for parameter identification cannot cover enough motion states of the robot joints, ...
A Review of Switched Inertance Hydraulic Converter Technology1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Digital hydraulics is a new technology providing an alternative to conventional proportional or servovalve-controlled systems in the area of fluid power. Digital hydraulic applications, such as digital pumps, digital valves ...
Water Retention Curve with Different Void Ratios over a Wide Suction Range and Its Application to Shear Strength
Publisher: ASCE
Abstract: Shear strength (τ) analysis has received considerable attention, because of its importance when designing various geotechnical structures, such as tunnels, retaining walls, shallow foundations, and slopes. Predicting the ...
Average Soil Skeleton Stress for Unsaturated Soils and Discussion on Effective Stress
Publisher: American Society of Civil Engineers
Abstract: The principle of effective stress is the most fundamental and important principle in soil mechanics. It serves as the foundation of modern soil mechanics. This paper starts with a discussion of effective stress expressions ...
