RISDiminishing Safety Margins of Telescoping-Boom Aerial Lifts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the height of telescoping-boom aerial lifts increase, the severity of tip-over accidents obviously increases. To reduce the probability of tip-over accidents, manufacturers use countermeasures such as outriggers and ...
Optimized Input-Shaped Model Reference Control on Double-Pendulum System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an optimized input-shaped model reference control (OIS-MRC) for limiting oscillation of multimode flexible systems. The controller is analyzed by using it to control an uncertain, time-varying double ...
Vibration Reduction Using Near Time Optimal Commands for Systems With Nonzero Initial Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The control of flexible systems has been an active area of research for many years because of its importance to a wide range of applications. The majority of previous research on timeoptimal control has concentrated on the ...
Three-Dimensional Dynamic Modeling and Control of Off-Centered Bridge Crane Lifts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When cranes lift payloads off the ground, the payload may slide sideways or swing unexpectedly. This motion occurs when the payload is not directly beneath the overhead suspension point of the hoist cable. Given that cable ...
Exact Modeling of n-Link Spatial Serial Structures Using Transfer Matrices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finding natural frequencies and mode shapes for flexible structures can be a challenging problem. Although well-known approaches exist for single flexible links, the problem becomes increasingly more complex when dealing ...
Slipping Dynamics of Slender-Beam Payloads During Lay-Down Operations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When laying down a long slender beam from a near-vertical orientation, to a horizontal position on a flat surface, the payload may slip and move suddenly in unintended and unpredictable ways. This occurs during crane ...
A Dynamics Based Hazard Analysis of Inverted Pendulum Human Transporters Using Data Mined Information
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a product is a complex dynamic system that interacts directly with a human, engineers must consider a wide range of possible motions and forces that the device could exert on the human. Such an analysis goes beyond a ...
Electromagnetic Model of Linear Resonant Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Linear resonant actuators (LRAs) are used extensively in consumer electronic devices such as cell phones and fitness trackers to provide haptic signals to users. This work presents a dynamic model of LRAs based, principally, ...
Tip Over Stability Analysis of Mobile Boom Cranes With Swinging Payloads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mobile boom cranes are used throughout the world to perform important and dangerous manipulation tasks. The usefulness of these cranes is greatly improved if they can utilize their mobile base when they lift and transfer ...
