Optimal Design of gear reducer random method
Abstract: For optimum design of gear decelerator The major methods of the study traditionally include investigation, program planning, technical design and working drawing, etc. Generally speaking, designers combine personal experience and materials collected in order to get a preliminary design by the traditional methods, optimizing variables like modulus, number, square wide, helical angle and transmission ratio of the gear and checking in the end. However, decelerators designed via the traditional methods are often of bigger size and conditionally work, leaving many practical engineering problems unsettled.
The main aim of the article is to study the method to minimize the size of the single column-shaped gear decelerator. The article centers on boundary constraints and performance constraints,and considers assorted conditions of the decelerators like intensity, rigidity and stability, etc, to settle the problems of Multi-objective functions。
According to the requirement of paper, this paper using random direction method, with the target of smallest Volume to optimization design of gear reducer. The optimize design of single cylindrical gear reducer include the mathematical model of optimal design problem and random direction optimization method and procedure. Once established mathematical model, Minimum volume reducer become a mathematical solving problem. Random direction method is a simple direct solution principle whose advantage is no special requirements on the characteristic of objective function, program calculation, and easy to use. Through the computer software (frotran Software) Programming, debugging and running and finally reached six reference data of minimum volume gear reducer, theoretically, the volume should be smaller than the conventional calculation, and the minimum volume is the optimal result.
