Abstract

The invention provides an excavator working device performance simulation calculation method based on a VBA system. A simulation system based on VBA is included, the simulation system based on VBA isconnected with multi-body dynamics software, the simulation system based on VBA comprises a setting module, and the setting module is connected with an excavation force calculation curve module, a mechanism performance curve module, an excavation range module, a whole vehicle stability module, an oil cylinder theoretical excavation force module and a cloud picture module. According to the method,parameterization of the multi-body dynamic model of the working device, automation of the calculation and analysis process and modularization of basic performance calculation are achieved, the calculation efficiency is greatly improved, and the personnel and time cost is saved. Due to the fact that performance calculation of the working device is modularized and shares one input file, when one module is improved, only the input file needs to be changed, other modules do not need to be input again, other modules automatically update results, the simulation efficiency is improved in a modularized mode, and use is easy and fast.

Description

technical field [0001] The invention relates to the field of performance simulation calculation of excavator working devices, in particular to a VBA system-based performance simulation calculation method of excavator working devices. Background technique [0002] The movement and stress of hydraulic excavator working devices are complex during the actual operation process, and the working conditions are changeable. As the main executive action parts, the working device has a structural performance that affects the overall performance, working reliability and safety of the excavator. important influence. The performance of the working device includes digging force, operating range, hinge point force, linkage efficiency and lifting capacity. At present, there are many methods for calculating the performance of working devices in China, including the use of dynamic software, language programming, etc., but they are generally aimed at a single performance, and few of them are c...
