| Abstract: | By analyses of the structure and operating features of a precision planter, we found that a feed wearability was the most important factor that influenced the planting quality. Based on the machine wearable reliability theory, an interference model of feed on wearable reliability, as well as the reliability calculation formula was developed. A fatigue accumulating principle for whole machine was developed according to the working conditions at different seasons and environments. As the complexity of the reliability of a planter, the optimization of reliability was considered in terms of economy, and the availability of a precision planter would be ensured by proper maintenance. |
