论自卸车副车架的功能与设计

随着各地基础建设不断增加,自卸车近年来一直保持较高产量,但目前我国的自卸车生产技术仍然处于较低水平,主要表现在材料、结构、工艺、技术含量、耐久性、舒适性乃至安全性等方面。文章从设计角度和理论方面对自卸车副车架结构进行了分析和探讨。自卸车副车架是自卸车的关键总成件,除了要固定液压系统外,还要承担重载和路面产生的动载荷。

斜拉-刚构组合体系桥零号块空间应力分析

以河谷汉江公路大桥斜拉桥主桥部分作为依托工程,针对其零号块空间受力问题,采用有限元软件midas FEA建立零号块有限元模型并进行相应分析.以施工过程中成桥运营阶段最大弯矩工况、最大剪力工况以及施工阶段最大双悬臂工况为控制计算工况,分析3种工况下零号块最不利内力情况.研究表明,在现有的设计条件下,结构受力可满足规范要求,相应的设计细节可为类似的工程提供借鉴.     

Survey as a Source of Statistics and Factors Affecting the Quality of Survey Statistics

Survey-taking, which normally involves sampling, has become a major data collection vehicle along with other means of obtaining raw data such as administrative systems and systems of special returns. This paper discusses the major aspects that should be addressed in conducting sample surveys. The proper treatment of these aspects is essential in ensuring production of quality statistics.     

How nutrition information frame affects parents’ perceptions of restaurants: The moderating role of information credibility

Adding easy-to-read information on menus is recommended for customers’ healthy food selections. But what format yields the best outcomes for restaurateurs has not been investigated. We use the emphasis framing effect as a theoretical lens to examine how the credibility of nutrition information affects parents’ perceptions of restaurant healthfulness and trustworthiness when exposed to two nutrition information frames on children's menus: numeric values only and numeric values with low-calorie symbols. The results of the experimental study show that parents who do not perceive nutrition information as being highly credible perceive restaurants providing numerical values only as more healthful and trustworthy. However, parents who do perceive nutrition information as being highly credible perceive restaurants as more healthful and trustworthy when both numeric values and low-calorie symbols are presented and have more positive perceptions overall. We advise restaurateurs to increase nutrition information credibility and provide additional easy-to-read information to elicit more positive perceptions.
