Abstract
The invention discloses a dynamics simulation modeling method for a working device of a loading machine. The method comprises that a three-dimensional model is transmitted to ADAMS/View, and then the dynamics simulation analysis is conducted; names, densities, the mass, the rotational inertia and products of inertia of all parts are changed, so that all parts are named again, and densities, the mass, the rotational inertia and products of inertia of all parts in the ADAMS/View are modified according to data measured in PRO/E; relative movement among all parts is limited by all restrictions, so that different parts are connected and bundled to form a mechanical system, and the magnitude of an external load applied to the working device of the loading machine is simulated through a step function; and the dynamics simulation model is checked. The method has the advantages of being beneficial to enabling of the output pressure and the flow of a pump to automatically meet requirements of the load and assisting and usage of a steering pump to match the pump and the load.
Description
Technical field
The present invention relates to the hydraulic technique field, relate in particular to a kind of working device of loader dynamics simulation modeling method.
Background technology
Hydraulic system is ingredient important in the shovel loader, and the upset of the swing arm lifting of shovel loader, scraper bowl and complete machine such as turn to all to need to drive to finish by hydraulic system at the elemental motion.The too high problem of oil temperature often appears in shovel loader in use hydraulic system, show according to factual survey, during shovel loader work oil temperature in hydraulic system higher be one of principal element of affecting hydraulic system and reliability of hydraulic component and complete machine work efficiency.Therefore, guaranteeing that the thermal equilibrium temperature of loader hydraulic system is in normal condition, is to guarantee the shovel loader reliably working, improves the key of hydraulic system efficient; Cause that the too high factor of oil temperature in hydraulic system mainly contains: the pressure loss of the volumetric loss of hydraulic pump and hydraulic cylinder, valve element and pipeline parts, the mechanical friction loss of each class component etc.These losses finally form power losses and generate heat, the heat that produces is dispersed into the space by heating radiator and each Hydraulic Elements, pipeline, tank surface except a part, load variations was larger when all the other major parts can cause the work of hydraulic oil temperature rising shovel loader, and machining device hydraulic system is driven by fixed displacement pump.Wheel Loaders ' Working Device mainly is comprised of scraper bowl, connecting rod, swing arm, rocking arm, scraper bowl hydraulic cylinder, swing arm hydraulic cylinder etc., and shovel loader drives equipment by hydraulic system and finishes the actions such as scraper bowl upset and swing arm lifting; During the shovel loader operation, the motion state of work clothes constantly changes, the gravity of each equipment and the acting force arm of load resistance also change accordingly thereupon, cause that at last the load that acts on the hydraulic system is that the suffered acting force of each hydraulic cylinder constantly changes.The moving characteristic of reading for the situation of studying more rapidly and accurately hydraulic system of loading machine working device power loss in a standard operation cyclic process and designed load-sensitive hydraulic system needs a kind of modeling method for this aspect.
Summary of the invention
The purpose of this invention is to provide a kind of situation that is conducive to understand power loss in the working cycle process, improve hydraulic system efficient, saves energy, can reduce the working device of loader dynamics simulation modeling method of equipment cost, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of working device of loader dynamics simulation modeling method mainly is comprised of following steps:

⑵ when be delivered to the three-dimensional model among the PRO/E among the ADAMS/View, the title of each parts, density, quality, moment of inertia and the product of inertia all can change, therefore, rename each parts, and revise density, quality, moment of inertia and the product of inertia of each parts among the ADAMS/View according to the data that record among the PRO/E;
⑶ limit the relative motion that each parts is asked by various constraints in ADAMS/View, and with this different parts have been connected mechanical system of Shu Zucheng, in working device of loader, the suffered external applied load of working device of loader mainly contains the gravity that inserts resistance, turn up resistance and material, in ADAMS, the size of the external applied load that working device of loader is suffered step functional simulation;
⑷ the left and right sides that on average be carried in each bucket tooth of shovel loader the shovel loader Dynamics Simulation Model is imposed restriction and external applied load after, with the self check instrument among the ADAMS/View Dynamics Simulation Model is checked, check whether model has inappropriate connection, redundant constraint.
The beneficial effect of working device of loader dynamics simulation modeling method of the present invention is: the situation that is conducive to understand power loss in the working cycle process, being conducive to assist utilizes steering pump to make pump and load mutually mate, improve hydraulic system efficient, make equipment can enter very soon normal operating conditions, improve the work efficiency of Whole Equipment, saved electric energy.
