The performance in vibration environment of switching apparatus containing mechanical contact is an important element when judging the apparatus’s reliability. A piecewise linear two-degrees-of-freedom mathematical model considering contact loss was built in this work, and the vibration performance of the model under random external Gaussian white noise excitation was investigated by using Monte Carlo simulation in Matlab/Simulink. Simulation showed that the spectral content and statistical characters of the contact force coincided strongly with reality. The random vibration character of the contact system was solved using time (numerical) domain simulation in this paper. Conclusions reached here are of great importance for reliability design of switching apparatus. 相似文献

Recent research on student learning in higher education has identified clear associations between variations in students’ perceptions of the academic environment and variations in their study behaviour. This study investigated a general theoretical model linking students’ demographic characteristics, perceptions and study behaviour with measures of outcome, and in particular, compared three accounts of the causal relationship between perceptions and study behaviour. Data were obtained from 469 postgraduate students at six British business schools. Path analysis was used to assess the causal relationships among the students’ age and gender, their scores on the Course Experience Questionnaire, their scores on the Revised Approaches to Studying Inventory and their ratings of general satisfaction with their programmes. This yielded evidence for the causal efficacy of most of the paths identified in the general theoretical model. In particular, as in the case of students taking more traditional academic subjects, there exists a bidirectional causal relationship between variations in students’ perceptions of the academic environment and variations in their study behaviour. 相似文献

While a vast literature exists on students and their learning, work on lecturers and their teaching continues to lag some
way behind. This paper explores the notion that the complexity of Higher Education (HE) today significantly impacts upon what
goes on in the classroom through a two-tiered study. Semi-structured interviews were conducted to explore lecturers’ perceptions
and experiences of teaching a specific module. Interviewees raised issues pertaining to the wider departmental, institutional
and socio-political context. Consequently, focus groups were run with key people in the University to explore their perceptions
of teaching and learning within the current HE climate. The findings suggest that lecturers perceive numerous external factors
to impinge upon their teaching and attempt to militate against these in various ways in order to achieve ongoing enhancement
of learning for students.
