Abstract
The invention discloses a loader device dynamics modeling method based on an automatic dynamic analysis of mechanical system (ADAMS) platform. The method comprises the following steps of: building an organization three-dimensional model, firstly, measuring the dimensions of parts, measuring the cylinder diameter, the rod diameter and the stroke of a bucket hydraulic cylinder and a movable arm hydraulic cylinder, and then, taking standard values of the dimensions of the bucket hydraulic cylinder and the movable arm hydraulic cylinder for three-dimensional modeling; drawing the three-dimensional models of the parts according to the measured dimensions after measuring the actual dimensions of the parts, then drawing the three-dimensional models of the parts of a loader working device in PR0/E, such as the bucket, the movable arm, a connecting rod, a rocker, the bucket hydraulic cylinder and the movable arm hydraulic cylinder; and assembling the parts after finishing the three-dimensional models of the parts, wherein the two hydraulic cylinders are completely consistent in the motion state in the assembly process. The loader device dynamics modeling method has the beneficial effects that the output pressure and the flow of a pump are automatically adapted to the requirement of a load, and the pump and the load are mutually matched up by auxiliary utilization of a steering pump.
Description
Technical field
The present invention relates to the hydraulic technique field, relate in particular to a kind of loader device dynamic modeling method based on the ADAMS platform.
Background technology
Hydraulic system is ingredient important in the loader, and the upset of the swing arm lifting of 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 loader in use hydraulic system, show according to factual survey, during 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 operating efficiency.Therefore, guaranteeing that the thermal equilibrium temperature of loader hydraulic system is in normal condition, is to guarantee the 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 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 loader, and machining device hydraulic system is driven by constant 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 loader drives equipment by hydraulic system and finishes the actions such as scraper bowl upset and swing arm lifting; During the 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 active force of each hydraulic cylinder constantly changes.Therefore, the dynamics of Wheel Loaders ' Working Device has important impact to the dynamic characteristic of research hydraulic system.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 loader device dynamic modeling method based on the ADAMS platform 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 loader device dynamic modeling method based on the ADAMS platform mainly is comprised of following steps:
⑴ set up mechanism's threedimensional model, at first measures the size of each component, measure cylinder diameter, the bar footpath and stroke of scraper bowl hydraulic cylinder and swing arm hydraulic cylinder after, get the standard value of scraper bowl hydraulic cylinder and each size of swing arm hydraulic cylinder and carry out three-dimensional modeling;
⑵ after measure the real size of each component, draw the threedimensional model of each component according to measurement size, in PR0/E, draw the threedimensional model of each component of working device of loader such as scraper bowl, swing arm, connecting rod, rocking bar, scraper bowl hydraulic cylinder, swing arm hydraulic cylinder;
⑶ after the threedimensional model of each component is finished, each component is assembled, in assembling process, two swing arm hydraulic cylinders are because motion state is in full accord, therefore, are integrated they are fixed, are integrated car body, wheel and the earth are fixed simultaneously.
The beneficial effect of the loader device dynamic modeling method based on the ADAMS platform 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 operating efficiency of Whole Equipment, saved electric energy.
The specific embodiment
The described loader device dynamic modeling method based on the ADAMS platform of the embodiment of the invention, its key step comprises:
⑴ set up mechanism's threedimensional model, at first measures the size of each component, measure cylinder diameter, the bar footpath and stroke of scraper bowl hydraulic cylinder and swing arm hydraulic cylinder after, get the standard value of scraper bowl hydraulic cylinder and each size of swing arm hydraulic cylinder and carry out three-dimensional modeling;
⑵ after measure the real size of each component, draw the threedimensional model of each component according to measurement size, in PR0/E, draw the threedimensional model of each component of working device of loader such as scraper bowl, swing arm, connecting rod, rocking bar, scraper bowl hydraulic cylinder, swing arm hydraulic cylinder;
⑶ after the threedimensional model of each component is finished, each component is assembled, in assembling process, two swing arm hydraulic cylinders are because motion state is in full accord, therefore, are integrated they are fixed, are integrated car body, wheel and the earth are fixed simultaneously.
