Failure Analysis on Tube Arm Cylinder Hydraulic Excavator
نویسندگان
چکیده
The Failure on tube rod arm cylinder hydraulic excavator caused to lose production and processing time mining site. Investigation included visual inspection, chemical analysis, metallography analyze, microhardness test. Tube material used high silicon type while the standard ST52 carbon steel type. was broken crack several pieces. composition of has different in sulfur content. From hardness test with micro method, sample lower compared hardness. Metallography analysis obtained phase same which is ferrite pearlite but grain size. Based this study, it can be resumed failure because impurities specification raw material.

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 ...

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 کاملEnergy-Saving Analysis of Hydraulic Hybrid Excavator Based on Common Pressure Rail
Energy-saving research of excavators is becoming one hot topic due to the increasing energy crisis and environmental deterioration recently. Hydraulic hybrid excavator based on common pressure rail (HHEC) provides an alternative with electric hybrid excavator because it has high power density and environment friendly and easy to modify based on the existing manufacture process. This paper is fo...
متن کاملAdaptive control for trailing arm suspension with hydraulic cylinder spring under practical constraints
Abstract— This paper presents an adaptive control strategy with LQ control of a quarter-car, which is ameliorated to smoothly follow the dynamically changing reference arm angle, in order to omit the heave sensor in this study. Linearized plant parameters are initially derived from model equation and then estimated by online estimator. LQ control method provides optimal control effort with corr...
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...
