Embodiment Construction

[0039]A design method for crankshaft dynamic balance. The model of the crankshaft part is sliced ​​and analyzed, that is, the model of the crankshaft part is segmented axially for a limited number of times. Finally, compare the obtained corresponding data with the preset data, and finally judge whether the dynamic balance of the obtained crankshaft part model is within the range of production requirements.

[0040] The corresponding data includes quality and radial direction.

[0041] The slice analysis step is based on the principle of rigid rotor dynamic balance analysis to set two balance correction surfaces and reference datum planes. The analysis steps are as follows:

[0042] A. First, select two balance correction surfaces as the reference for dynamic balance calculation. After one balance correction surface, select another balance correction surface by rotating or moving parts;

[0043] B. The user then selects an end face of the crankshaft part as the reference datum...

Abstract

The invention discloses a design method for dynamic balance of crankshaft, which is characterized in that: conduct slicing analysis on a model of crankshaft model, that is, segment the model of crankshaft component for limited times to a plurality of slices and then extract corresponding data of the crankshaft component model; compare the data with the preset data to judge whether the dynamic balance of the crankshaft component model is within the scope of production requirements. This method, with convenient operation, accurate and fast calculation and analysis, is able to conduct the analysis on the dynamic balance of the modeled crankshaft component and reflect in time the status of component dynamic balance, so that the design personnel are able to modify the crankshaft design in time to reach the required dynamic balance and completely prevent the testing of finished products via a dynamic balance machine. Therefore, compared with conventional method, this method not only enhances the calculation precision but also saves much investment and materials.

Description

technical field [0001] The invention relates to a dynamic balance testing method for crankshaft parts, in particular to a design method for testing the crankshaft dynamic balance of crankshaft parts. Background technique [0002] The traditional design of crankshaft parts is usually designed by the designer based on his own practical experience, and then the crankshaft parts are processed and formed according to the design of the designer, and then taken to the dynamic balancing machine for dynamic balance calibration. This is the method generally adopted in China at present. , so the improvement of this step of the dynamic balance test is limited to the improvement and design of the dynamic balancing machine. For dynamic balancing machines, the calculation accuracy of dynamic balancing is not high, and the design and development time is also longer, and more funds are invested. [0003] Therefore, the design method of completing the dynamic balance test in the design proce...
