Testing method for wheel loader energy efficiency

Abstract

The invention provides a testing method for wheel loader energy efficiency. The method comprises the steps that a wheel loader right faces and is fixed to the front face of materials to be tested, and a first preset distance is reserved between the wheel loader and the materials to be tested; an auxiliary loading device is fixed to the side, where a second preset distance is reserved, between the materials to be tested; the wheel loader provided with an auxiliary fuel tank is controlled to shovel the materials to be tested, and the shoveled materials to be tested are loaded in the auxiliary loading device; the materials are weighed through first and second weighing devices respectively, and the fuel consumption amount of the auxiliary fuel tank and the weight of the materials, to be tested, loaded by the auxiliary loading device are calculated; according to the fuel consumption amount and the weight of the loaded materials to be tested, the energy efficiency value is calculated, a walking route is accurately regulated, the fuel consumption amount and the weight of the loaded materials to be tested of the regulated route are obtained through measurement, and the more objective and accurate calculation value is obtained. Therefore, the comparative result of the calculated energy efficiency value is more accurate, the operating energy efficiency level of wheel loaders of different enterprises can be measured more accurately, and the basis of selecting the loaders is provided for users.

Description

technical field [0001] The invention relates to the field of energy saving and emission reduction of engineering machinery, in particular to a method for testing the energy efficiency of a wheel loader. Background technique [0002] Energy conservation and emission reduction work is one of the country's long-term development strategic measures, and the task of promoting energy conservation and emission reduction of construction machinery is imminent. At the construction site of construction projects, the energy efficiency level of wheel loaders (also called tire loaders) has attracted widespread attention from users and manufacturing companies, because the energy efficiency level of wheel loaders directly determines the user's input cost and the manufacturer's cost. product level, but also affect environmental protection. Therefore, the research on the ratio of the weight of material shoveled by the tire loader within the unit fuel volume to the unit fuel volume reflects it...

Problems solved by technology

[0003] The method for testing the fuel consumption of tire-type loaders in the related art is to use the test method of V-shaped shovel-loading operation; wherein, the specific process of the V-shaped test method is as follows: the operator drives the tire-type loader and loads the vehicle through the first route. materials, and return to unload the shoveled materials along the second route, and then calculate the fuel consumption of the shoveled materials, so as to calculate the fuel consumption level of the tire loader, lack of weighing of shoveled materials, and lack of energy efficiency index evaluation; Compared with multiple tire loaders in the test, it is difficult to compare the tire loaders with lower fuel consumption for users to choose

[0004] Moreover, in the related technology, during the entire test process, due to the uncertain driving route, the error generated by the operator is very large, and the V-shaped route is completely judged by the operator subjectively, and the V-shaped test route has no advance and retreat of the tire loader. points, resulting in large differences in measurement results, the comparison of the results measured by this method makes the comparison less accurate, so that users cannot accurately select the tire loader with lower fuel consumption; at the same time, it is not proposed Test method for energy efficiency index of wheel loader
