[0118] 1. The engineering processing method of the new discrete hybrid leapfrog algorithm coding

[0119] The traditional hybrid leapfrog algorithm is generally optimized to solve the objective function of continuous variables and unconstrained conditions. For the solution of this hybrid variable of the two-stage gear reducer, the traditional hybrid leapfrog algorithm must be improved. , can be applied to practical engineering problems.

[0120] 1.1 Mapping processing of discrete variables

[0121] All discrete types are mapped in the form of a table, and the size of the variable is represented by the position in the table. At the same time, the size of the table is automatically set according to the variable range of the variable, as follows:

[0122] 1) Number of teeth: For integer variables such as the number of teeth, because the spacing is fixed at 1, when mapping, the first number in the table is the minimum value of the variable, and then by analogy, gradually add 1 un...

Abstract

The invention discloses a design method of a two-stage cylindrical gear reducer, which comprises the following steps: (1) determining working conditions, (2) determining an objective function and a design variable, and (3) encoding and engineering processing of the design variable, specifically including mapping processing of discrete variables and encoding processing of continuous variables; (4)determining a constraint condition and a fitness function; and (5) substituting the established mathematical model into a discrete shuffled frog leaping algorithm, and outputting an optimization calculation result. According to the design method, manual calculation can be greatly reduced, the basic parameters of the two-stage gear reducer can be automatically calculated and designed only by inputting the basic parameters such as the target type, the working condition and the constraint condition into the program provided by the invention, and the result is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a design method of a two-stage cylindrical gear reducer. Background technique [0002] The gear reducer is an independent closed mechanical transmission device between the prime mover and the working machine, which can reduce the speed and increase the torque. It is a mechanical component widely used in industrial and mining enterprises, transportation, construction and other departments. [0003] The traditional design method is that the designer preliminarily formulates a design plan based on the data provided by various materials and documents, combined with his own design experience, and the existing reducer, and then checks the plan. If the check is passed, then The program can be determined, otherwise, redesign. Reducers designed in this way are often oversized, may not be the optimal design, and are inefficient. Therefore, in order to reduce the cost of the reducer and ...
