Title: Boom equipment for transport of fluid
Inventor: NUNOHARA TATSUYA
IPC: E04G21/04
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To provide boom equipment for transport of a fluid which suppresses the vibration of a boom. SOLUTION: A sensor 52 detects a change in a stroke (x) due to vibration and gives it to CPU 50. The CPU 50 fetches the given stroke (x) and computes a target pressure F being a target driving force, according to the following equation, F=F0-k.(x-x0)-c.x'. Herein F is a driving force (pressure) in non-vibration, (k) and (c) coefficients, x0 a cylinder length in non-excitation, (x) the cylinder length in excitation and x' a moving speed of a cylinder. The moving speed x' of the cylinder is obtained by dividing a change in the cylinder length (x) by a time. The CPU 50 gives a servo amplifier 48 the computed target pressure F as a drive command. Thereby the pressure of the cylinder 18 is controlled so that it be equal to the computed target pressure F. Accordingly, the cylinder 18 comes to have functions of a spring and a damper.
