均布压力下T型连接极限承载特性试验研究

针对复合材料舵翼骨架与蒙皮连接,设计了两种T型连接结构,并对其在波浪砰击载荷作用下的极限承载特性进行了试验研究。根据结构承载特点,提取典型局部试验缩比模型,给出了均布压力下T型连接试验载荷等效方法。试验比较了两种T型连接的承载特性差异,研究了跨距对T型连接初始刚度、极限破坏载荷以及极限承载弯矩的影响规律。试验结果表明:构型A存在明显的初始破坏,但极限破坏载荷大于构型B;极限承载弯矩基本不随跨距改变,可作为不同跨距、不同构型T型连接优劣衡量标准。最后,基于试验结果、载荷等效与缩比原则,提出了T型连接承载特性评价方法。     

Price and capacity decisions of service systems with boundedly rational customers

We consider price and capacity decisions for a profit‐maximizing service provider in a single server queueing system, in which customers are boundedly rational and decide whether to join the service according to a multinomial logit model. We find two potential price‐capacity pair solutions for the first‐order condition of the profit‐maximizing problem. Profit is maximized at the solution with a larger capacity, but minimized at the smaller one. We then consider a dynamically adjusting capacity system to mimic a real‐life situation and find that the maximum can be reached only when the initial service rate is larger than a certain threshold; otherwise, the system capacity and demand shrink to zero. We also find that a higher level of customers’ bounded rationality does not necessarily benefit a firm, nor does it necessarily allow service to be sustained. We extend our analysis to a setting in which customers’ bounded rationality level is related to historical demand and find that such a setting makes service easier to sustain. Finally we find that bounded rationality always harms social welfare.
