Dynamic Simulation of Hydraulic Truck Crane Hoisting System Based on AMESim

Abstract

This paper is made from a certain type of truck crane hydraulic lifting mechanism system as an object, then the second lifting working condition is analyzed. With AMESim, according to the hydraulic system diagram building lifting mechanism hydraulic system simulation model, hereby corresponding simulation conditions is set and the effects of secondary slide response on input signal, hoisting load, discharge and speed of pump, fluid resistance of one-way throttle is studied. This research on truck crane hoisting mechanism hydraulic system provides the theory basis for the design improvement, the relevant research methods and means have reference on the research of other engineering machinery hydraulic system working characteristics.

The Fault Analysis and Simulation of Vehicle Hydraulic Shift System Based on AMESim

“…Power source signals to the mass body and spool are respectively used to simulate the movement of the clutch pedal and the shift lever .The maximum displacement of clutch separation cylinder is 0.1m and the displacement range of the shift cylinder piston ranges from -0.02m to 0.02m. The process of engaging and shifting gear action consists of the following steps [8]: depress the clutch pedal to make it separate rapidly, engage gear operation forthwith. After that make the clutch combine at an appropriate speed, then separate it again to shift the gear.…”

“…Normal and fault response curves can be shown in a frame of the output chart at the same time through the batch simulation and operation function of AMESim while observing the results. Then the fault feature is extracted and saved into sample database.The process of engaging and shifting gear action consists of the following steps[8]: depress the clutch pedal to make it separate rapidly, engage gear operation forthwith. After that make the clutch combine at an appropriate speed, then separate it again to shift the gear.…”
