Simulation

Our project concentrates on using PlanOpSim’s optimization algorithm software to enhance the efficiency and functionality of nanostructured optical devices. Unlike traditional engineering methods, in which a structure is designed and then tested, inverse design begins with a target optical response and uses computational methods to determine the optimal nanostructure to achieve that function. For our first objective, we designed a metasurface capable of displaying two distinct holographic images depending on whether the incident light is in the TE or TM polarization state. For the second, we aimed to design a metasurface that produces specific colors by controlling the interaction of light with carefully engineered nanostructures.

The low numerical aperture multimode fiber project is a detailed fiber design and simulation developed by a team of undergraduate senior students. As such, the inputs were determined through discussion with our project customer, ASML. We are designing a fiber to support ASML’s YieldStar (YS) optics sensor for scanning wafers using white light with the wavelength range of 400 to 1000 nm and another fiber to operate at a wavelength of 1070 nm meant to preheat a mirror for a separate lithography machine.

Tow Tank devices are used in testing boat and aerodynamic models for things like aerodynamic drag and lift. These devices typically cost around $20,000 which is the reason not every school has access to such a device. Here in the University of Rochester, we don’t have our own tow tank device, but we do have a swimming pool, and a passion for solving problems. In this post, we are showcasing our prototype for a tow tank that can be assembled and used in the gym swimming pool. The cost of the prototype and the completed final device is less than $1000!

The main goal of this project is to build, assemble, and successfully test an accelerated testing machine for the India Mark II. In the India Mark II pump, the water gaskets wore off frequently during the pumping of water and needed frequent replacement which proved costly. To counter the problem, the project below proposes an accelerated testing machine composed of a slider-crank mechanism. The mechanism incorporated a flywheel driven by a motor that ensures continuous harmonic motion that replicates pumping mechanisms in the field. The mechanism was designed, simulated and a finite element analysis carried out in CAD software. These are covered in the report along with testing results and recommendations provided for improvement of future designs.​

Modern mechanical engineers utilize computers but do not fully understand how the computer performs its computations. Understanding the fundamentals will give them a better understanding to the limitation of traditional computing. To address this gap between functionality and understanding, we built a 4ft by 6ft physical 3-bit adder to blow up the tiny processes that go on inside of a computer. Using a system of logic gates, where marbles act as inputs and outputs, our machine is able to add numbers 7 and below to each other and produce an output in binary.

The cautery phantom senior design team will engineer and improve a system that will arrest artificial blood flow in response to electrocautery in a tissue phantom manufactured by Simulated Inanimate Models, LLC (SIM). To solve this problem, we have investigated methods of vessel constriction by lining the tissue phantom blood vessel wall with a thermoresponsive material, coagulating the artificial blood by introducing proteins and chemicals into the mixture, and by making the blood vessel with a shape memory polymer.

The Rossell Hope Robbins Library is underutilized by many students on campus due to the lack of awareness of the library and its resources. To promote awareness for the library, this project contains designs for a “life-size” portable chess set with medieval themes.

Development of polymers to simulate kidney tissues for surgical training of medical students at UR Medical Center.

A renewed focus on environmental concerns means that fuel efficiency and emissions of engines are of significant importance. A current design for a mixing nozzle exists, but the fuel residence could be higher and the pressure drop could be lower. A longer fuel residence time ensures smooth distribution of fuel and a more efficient burn. A lower pressure drop means that less energy is lost by the motion of the fluid through the mixer.

Helmets in the NFL are not effective enough to safeguard the health of the players. Players sustain concussions which can not only bench them, but leave life-long brain damage from the accelerations experienced during impact. As part of the project to improve the helmet, simulations were used to test material properties of different components of football helmets, such as hard foams, soft foams, and the shell. Data from the simulations were analyzed with performance metrics provided by the NFL.

The project aims to design a steering system for robots used in various ECE courses. The robotic system has issues with lifetime, maneuverability, and mobility. The new model was designed with an aim to direct most of the off-axis load into the chassis while still maintaining the capability of the DC motor driving the wheel. These improvements helped in significantly increasing the lifetime of the motors. Additionally, the ability to steer each wheel independently increased the mobility of the robot.

Using a rope of LEDs, connected to a Raspberry Pi with our software, we will read the audio signal from an HDMI cable and display colors on the LED strip that match the tone of the music. . The goal of our project is to be able to create a visualization to convey a similar feeling to people that are unable to hear the music.

The Laboratory for Laser Energetics (LLE) at the University of Rochester is in need of a portable and educational display that showcases the mission and capabilities of the facility. The project is a representative and visually captivating model that demonstrates the laser amplification process of Chirped Pulse Amplification (CPA). This technique was invented by the LLE and revolutionized the industry.

The project goal was to create methods to control the brakes, steering angle, and accelerator position of a Baja SAE off-road vehicle in a manner that allows the remote driving of the car. The team has created detailed models, simulations, and system documentation to ensure a strong foundation for the continuation of the project in the coming year. This project hopes to create new opportunities for future undergraduates to work on problems related to autonomous vehicles.

For spinal surgeons who face difficulty visualizing the nerve root during spinal decompressions, the Meramec suction/elevator is a surgical instrument that combines multiple instrument functions to free surgeons’ hands and increase OR efficiency. It combines the functionality and familiarity of existing suction tips and manual elevators with end effector geometry specific to the lumbar nerve roots, reducing the need to switch instruments. This improves OR workflow and increases patient safety.

Our team is working to design and develop a functional bladder phantom that sits in a model of the human torso. This model is to be used in the validation and testing efforts of our customer, Curbell Medical’s, bladder bioimpedance sensor device. The model must be anatomically comparable to that of the average human in terms of both structure and function.
