A hydraulic simulation test system and test method for non-road mechanical working conditions

Abstract

The invention provides a hydraulic simulation test system for non-road machinery working conditions, which is characterized in that: it includes a main control upper computer, an engine controller, a hydraulic absorption adsorption component and a traveling power absorption component; the engine controller is used for the engine of non-road machinery The main control host computer controls the operation sequence of each hydraulic branch of the non-road machinery through the hydraulic absorption adsorption component according to the preset control strategy. The driving resistance is simulated. The hydraulic simulation test system and test method for non-road machinery working conditions described in the present invention solves the problem that the current non-road machinery industry can only perform relevant tests of hydraulically driven machinery in the actual field work mode, and the existing test method is extremely difficult. It is a technical problem that is greatly limited by the venue and season, and the driver's operating habits have a great impact on the test results.

Description

technical field [0001] The invention belongs to the field of non-road machinery testing, and in particular relates to a hydraulic simulation testing system for non-road machinery working conditions. Background technique [0002] In order to control the realization of non-road machinery energy saving and emission reduction targets, the four-stage non-road emission regulations have made requirements for the OBD function (on-board diagnostic system) of non-road machinery and the typical working conditions of the whole machine. However, due to the application of non-road machinery There are many scenarios, the testing and certification work is difficult, and the working conditions cannot be reproduced, and the traceability is poor. Based on the above reasons, it is necessary to unify the test methods and working conditions for non-road machinery in order to obtain reproducible evaluation results under unified standards. Test conclusions can be more objective and authoritative. ...

Problems solved by technology

[0008] In view of this, the present invention aims to propose a hydraulic simulation test system and test method for non-road machinery working conditions, which solves the problem that the current non-road machine industry can only use the actual field work method to carry out relevant tests of hydraulically driven machinery. There are technical problems that the test method is greatly restricted by the venue and season, and the driver's operating habits have a great impact on the test results;

[0009] It further solves the technical problem that the test results of the same machine operated by different drivers are very different, and even the same machine operated by the same driver cannot reproduce the test conditions
