Abstract: This paper presents a multi-objective optimal design method for gravity compensators with consideration of minimizing the joint reaction forces. High performance of the gravity compensation is achieved while the joint ...
Impact Elastohydrodynamic Lubrication Analysis of Transversely Isotropic Materials in Point Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the traditional elastohydrodynamic lubrication (EHL) field, surface elastic deformation is usually determined using an elastic half-space model for isotropic materials. However, this theory may be inefficient when applied ...
Enhancing Dynamic Force Characteristics of a 3-RPS Parallel Manipulator Using Integrated Mechanical Springs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study introduces an approach for reducing actuation forces in a 3-RPS (R: Revolute, P: Prismatic, U: Universal, S: Spherical) parallel manipulator through the integration of mechanical springs. Three distinct ...
Reliability-Based Analysis and Optimization of the Gravity Balancing Performance of Spring-Articulated Serial Robots With Uncertainties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article proposes a method for analyzing the gravity balancing reliability of spring-articulated serial robots with uncertainties. Gravity balancing reliability is defined as the probability that the torque reduction ...
Consistency of Bond–Slip Models in Simulating the Bond between ETS-FRP Bars and Concrete and the Shear Contribution of the Strengthening System
Publisher: American Society of Civil Engineers
Abstract: Predicting the shear contribution of a fiber-reinforced polymer (FRP) strengthening system in a reinforced concrete (RC) beam strengthened using the embedded through-section (ETS) method remains challenging due to the ...
