Embodiment Construction

[0032] Such as figure 1 As shown, the decoupling model-based life sensitivity analysis method of the clamping end structure of the ear pollination machine in this embodiment includes the following steps:

[0033] S1. Determination of influencing factors of pollinator life based on test data decoupling:

[0034] According to the working principle of ear picking pollination machine, it mainly includes structures such as driving trolley, electric telescopic rod, swing rod device and swing rope. Based on this, three main working parameters that affect the life of ear picking machine are determined, namely parameter x 1 : The forward speed v of the driving car in the field, the parameter x 2 : The rotation speed ω of the pendulum device and the parameter x 3 : The amount of expansion and contraction Δl of the electric telescopic rod, here select different field forward speed levels, and label it as i, v i is the field forward speed of the i-th level, i=1, 2, ..., N, N is the tot...

Abstract

The invention discloses a decoupling model-based ear pulling pollination machine clamping end structure life sensitivity analysis method. The method comprises the following steps: S1, determining pollination machine life influence factors based on test data decoupling; S2, designing a working condition data set based on a random experiment; S3, calculating the service life of the clamping end structure of the ear pulling pollination machine; S4, establishing an optimal sensitivity model based on a decoupling model; and S5, analyzing the service life sensitivity of the clamping end structure of the ear pulling pollination machine based on the decoupling model. The method is high in solving precision, and has important practical significance for realizing quantification of influence factors on the service life of the clamping end structure of the novel ear-pulling pollination machine.

Description

technical field [0001] The invention relates to a method for analyzing factors affecting mechanical life, in particular to a method for analyzing the life sensitivity of a clamping end structure of an ear pollination machine based on a decoupling model. Background technique [0002] As an important equipment in the field of agricultural breeding, the ear pollinator is an important equipment in the field of agricultural breeding. With the development trend of agricultural modernization, my country's mechanical assisted breeding technology is also constantly innovating, and the number of times the ear pollinator is used is gradually increasing. Pay attention to. At present, the influence of the complex and diverse operating environment of the ear pollination machine, external factors and the clamping end structure life of the ear pollination machine on the operating quality and reliability of the ear pollination machine has not been considered. [0003] In this context, it is ...
