Optimum Design of Hydraulic Excavator
Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". In this paper the hydraulic shovel excavator is analyzed through the D-H method. The shovel working device with the bucket capacity of 36m3 is optimized. The determination of the objective function, variables and constraints are described in ...
متن کاملA Critical Review on Kinematics of Hydraulic Excavator Backhoe Attachment
The Hydraulic excavator machines are heavy duty earth mover consisting of a boom, arm and bucket. It works on principle of hydraulic fluid with hydraulic cylinder and hydraulic motors. The Hydraulic excavator backhoe operation require coordinated movement of boom, arm and bucket to control the bucket tip position by following a desired trajectory and to use the excavator machines effectively in...
متن کاملAnalysis of Active Suspension Systems with Hydraulic Actuators
Most of the existing active suspension studies assume that an ideal force actuator exists and will carry out the commanded force accurately. In reality, due to the interaction between the hydraulic actuator and suspension system, the lightly damped modes of the plant will generate lightly damped zeros (LDZ) for the servo-loop system, which confines the closed-loop performance to a low frequency...
متن کاملA Novel Energy Recovery System for Parallel Hybrid Hydraulic Excavator
Hydraulic excavator energy saving is important to relieve source shortage and protect environment. This paper mainly discusses the energy saving for the hybrid hydraulic excavator. By analyzing the excess energy of three hydraulic cylinders in the conventional hydraulic excavator, a new boom potential energy recovery system is proposed. The mathematical models of the main components including b...
متن کاملA Haptically Enhanced Operational Concept for a Hydraulic Excavator
In mobile hydraulic machines, like excavators, backhoe loaders, wheel loaders, and forklift trucks, haptic human-machine interfaces are not in use. Today, the machines are operated with mechanical-hydraulic joysticks. Each joystick axis controls a single hydraulic actuator. This leads to not very easy to use operational concepts. Since electrohydraulic systems with electronic joysticks are avai...
