(in Chinese) DOI: 10.3901/JME.2020.23.001 http://doi.org/10.3901/JME.2020.23.001 Oil churning losses have a significant influence on lubricating performance, transmission stability, and energy-saving economy of transmission systems. Research on the predicting and controlling methods of gear churning losses contributes the optimal design and energy saving of the transmission system. Studies show that oil churning losses occupy more than 50% of total power losses of reducers/gearboxes under high speed condition, and that churning losses change significantly with the lubricating condition, geometrical structure, and working condition. Churning losses is complex in mechanism and involve extensive factors, therefore exploring its mechanism and mastering energy consumption characteristics is the recent research difficulties and hotspots. Lots of researches focused on the modeling and application of oil churning losses, but many of them aimed at some a special working condition and lacked universality and systematisms. Thus, it is necessary to thoroughly discuss and summarize churning losses. By combining recent research progress in theory, simulation and bench test, the churning losses are studied based on quantitative and qualitative analysis on different influence factors. Modeling methods and applications are emphasized and the methods of reducing churning losses are given in detail.

(in Chinese) DOI: 10.12382/bgxb.2022.A018 http://doi.org/10.12382/bgxb.2022.A018 Transmission efficiency is one of the important indicators for the performance assessment of vehicle transmission device，which needs to comprehensively consider the influence of various factors. Considering the influence of many factors in the transmission process，a weighting method of no-load power loss and loading efficiency based on median rank is proposed to shorten the test time and obtain a stable comprehensive performance evaluation index of transmission efficiency in straight driving mode，in which the gear positions include six straight driving gear positions and two reverse gear positions under no-load and loading conditions，and four rotating speeds are tested for each gear position. There are seventy-five transmission efficiency test samples at each rotating speed. The median rank weighting method for no-load power loss and loading efficiency is used to obtain the normalized comprehensive performance assessment indicator and give the criterion of whether the comprehensive performance of vehicle transmission efficiency is qualified.The results show that the stable normalized comprehensive performance assessment indicator of transmission efficiency under straight driving mode could be obtained in the first 10 speed measuring points, while the transmission performance of vehicle transmission device could be judged from the criterion.

However, with the complexity and uncertainty of the evaluation system, the point prediction performance of efficiency will gradually decrease. Based on this, a DEA-BP neural network confidence interval prediction model is proposed. Firstly, the non-archimedes infinite CCR model is constructed to evaluate the efficiency of the system. Secondly, the confidence interval prediction model of BPNN is constructed, and the point prediction is transformed into interval prediction. Finally, the interval comprehensive verification is carried out by PICP, NMPIL and CLC models. The three-stage model is applied to the tourism efficiency forecast of provinces and cities along the &#x00026;ldquo;Belt and Road&#x00026;rdquo;, and the efficiency of each province and city is classified according to the forecast results and suggestions for improvement are proposed. Because the BPNN confidence interval prediction model is difficult to confirm the best model, the results of this paper still need to be improved, but it has certain reference.</p>

DOI: 10.3901/JME.2016.01.087 http://doi.org/10.3901/JME.2016.01.087 针对支持向量机(Support vector machine, SVM)的惩罚系数难以确定、核函数必须满足Mercer定理等问题，相关向量机(Relevance vector machine, RVM)应运而生以解决上述问题，并在趋势预测等领域得到一定的应用。核函数是决定RVM预测精度的关键因素之一，目前的研究通常是人为选择单一核函数，因此增加了对参数的依赖性并降低了RVM预测的鲁棒性。为了解决以上问题，提出一种新的自适应多核组合RVM预测方法。该方法首先选择多个核函数，利用粒子滤波产生核函数权重，建立多核组合RVM集，然后经过不断地迭代预测、权值更新和重采样，自适应获取最优多核组合RVM，从而自适应融合多个核函数的特性，克服基于单一核函数RVM的局限，提高预测精度和鲁棒性。利用仿真对提出方法进行了验证，并将其应用于机械设备的剩余寿命预测，取得了比基于单一核函数RVM更好的预测效果。
