Description: 有r个人在一楼进入电梯，楼上共有n层。设每个游客在任何一层楼下的概率相同，试建立一个概率模型，求直到电梯中的人下完为止，电梯需停次数的数学期望，对r=10，n=8（如西一楼）进行计算机模拟验证。(There are r people in the first floor into the elevator, upstairs, there are n layer. The probability of each visitors at any level below the same, try to establish a probabilistic model for the people under the elevator until the end date, mathematical expectation, lift to stop times of r=10, n=8 (such as the West Building) computer simulation.)

Description: 在本实验中，电梯模拟器外部结构图如下图所示，共有4层，分别编号为1，2，3，4。采用电机驱动电梯箱体的上升与下降等操作，当电机正向旋转的时候，电梯保持上升状态，当电机反向旋转的时候，电梯保持下降状态，而当电机停止转动时，电梯也保持静止状态。由于电机不具备自锁功能，即在一定的确定电压下保持静止状态，因此要在物理上采用某种措施保证电机上述功能的顺利实现。经查阅相关的资料，我们发现可以利用蜗杆涡轮传动系统来实现，见下图,这就是利用阿基米德蜗杆的蜗杆传动，它具有传动平稳，振动、冲击和噪声均很小，而且可获得较大的传动比，更重要的是当蜗杆的导程角小于啮合轮齿间的当量摩擦角时，机构具有自锁性。(In this experiment, the elevator simulator external structure diagram as shown below, there are 4 layers, numbered 1, 2, 3, 4, respectively. The motor driving elevator box in ascending and descending operation, when the motor is rotating, lift up state, when the reverse rotation of the motor, elevator to keep down state, and when the motor stops rotating, elevator also remain static. As the motor does not have self-locking function, that is, under certain voltage to maintain static state, so some measures should be adopted in physics to ensure the smooth realization of the above functions of the motor.)

Description: Direct numerical simulations have been performed to study the flow around
a high-lift turbine blade for low and high levels of turbulence intensity. Initially a two-dimensional simulation has been carried out to study the dominant two-dimensional physics. The chord Reynolds number is approximately
Re = 45000. Moreover, three-dimensional simulations are conducted using two
sets of low and high level background noise mimicking the effect of free stream
turbulence. For both cases the response of the boundary layer to external
perturbations is manifested as streaky structures on the suction side and longitudinal structures on the pressure side.

Description: We present this paper as an experimental study of employing Magnus Effect in an aircraft wing. The scope and interest of study of
Magnus Effect and its application in Aerospace Engineering is widely increasing all over the world to make use of the Magnus
Force for enhanced Lift by Drag Ratio. Most of the trials weren't successful due to the heavy Drag Force produced by large
cylinders, even though sufficient Lift Force was generated

Description: 对于电梯内发出的请求，方法不变，对于电梯外发出的任务请求，可以用两个队列分别保存向上和向下的请求，在各电梯处理电梯内发出的请求的时候，每到达一层，就检查上述的两个队列，看是否有匹配项，若有则停留3秒，从队列中去除任务，若有电梯没有电梯内发出的请求可处理而停滞，则只要上述的两个队列不空，就赶去处理，这种方法从代码方面来说相对简单，但这样做的话任务的完成具有不可预测性，也会造成一个请求，多个电梯响应的问题，不知道老师怎么想的？(For the elevator the request method for the same, a lift task request, you can use two queue stored up and down the request, when the elevator elevator processing request, each reached a two layer, check the queue, see if there is a match, if there is a stop for 3 seconds, remove the task from the queue, if there is no elevator elevator in the request processing can be stopped, as long as the two queue is not empty, the rush to the processing, this method from the aspects of the code is relatively simple, but do this task is unpredictable. Will cause a request, a plurality of lift response problems, teachers do not know how to think?)

Description: 三菱PLC控制的四层电梯毕业设计论文 本文介绍一种电梯 PLC 控制系统。电梯是垂直方向的运输设备，是高层建筑 中不可缺少的交通运输设备。它靠电力，拖动一个可以载人或物的轿厢，在建筑 的井道内导轨上做垂直升降运动，在人们生活中起着举足轻重的作用。而控制电 梯运行的 PLC 系统也要求越来越高，要求达到电梯运行的“稳、准、快”的运行 目的。该系统主要由 PLC、逻辑控制电路组成。其中包括交流异步电动机、继电 器、接触器、行程开关、按钮、发光指示器组成为一体的控制系统。(Four storey elevator graduation design paper controlled by MITSUBISHI PLC A kind of elevator PLC control system is introduced in this paper. Elevator is a vertical transportation equipment, and it is an indispensable transportation equipment in high-rise buildings. It relies on electricity to drag a car that can carry people or things, and does a vertical lift in the guideway of the building's well. It plays an important role in people's life. And the PLC system that controls the operation of elevators also requires higher and higher requirements, so as to achieve the goal of "stable, accurate and fast" operation of elevators. The system is mainly composed of PLC and logic control circuit. It includes AC asynchronous motor, relay, contactor, stroke switch, button and luminous indicator.)
