As a peculiar product in China today,farm vehicles play an important role in economic construction and development of the countryside,but its work reliability remains low.In this paper truncated tracking was used to solve the low reliability of farm vehicles.Relevant reliability data were obtained by tracking a certain model vehicle and conducting reliability experiments.Data analysis revealed the weakest part of the vehicle system was the engine assembly.The theory of Artificial Neural Network was employed to estimate a parameter of the reliability model based on self-adaptive linear neural network,and the reliability function educed by the estimation could provide important theory references for reliability reassignment,manufacture and management of farm transport vehicles. 展开更多

Energy conservation and emission reduction are the focus worldwide.Farm vehicle engine would be more efficient if it is injected a little hydrogen during work,meanwhile,the emission of the vehicle would be decreased.Nowadays,there are many kinds of onboard hydrogen production methods,among which the microwave plasma method is regarded as the best.In order to develop an onboard hydrogen production system using microwave plasma,a new corresponding test bed was designed and developed in this research.The ethanol,water and air from the three supply pipelines were mixed and evaporated into gas mixture,and then the mixture was further created into hydrogen through microwave plasma reaction.In the test bed,a hydrogen production environment required for the reaction was provided,and hydrogen would come into being when the air was broken down by the plasma under the conditions of 0.1-0.7 atm.Furthermore,the reaction conditions could be controlled precisely,and real-time environmental data and spectral data could be collected during the hydrogen production.The experimental results showed that onboard hydrogen production could be achieved on this test bed,and the hydrogen amount produced could be adjusted to simulate real vehicle working conditions.In addition,the system is of rapid response,high precision and reliability,which can be applied in new products developments of the onboard hydrogen production system. 展开更多
