Pneumatic battery : a chemical alternative to pneumatic energy storage
Pneumatic power is traditionally provided by compressed air contained in a pressurized vessel. This method of energy storage is analogous to an electrical capacitor. This study sought to create an alternative pneumatic device, the pneumatic battery, that would be analogous to an electrical battery. …

Pneumatic ergonomic crutches
… To address these issues, we developed the pneumatic ergonomic crutches (PEC) that consisted of a pneumatic sleeve orthosis, an energy harvesting system and an energy storage system. The pneumatic sleeve orthosis utilized a soft pneumatic actuator, called fiber-reinforced elastomeric …

Modeling and Analysis of a Novel Pneumatic Artificial Muscle and Pneumatic Arm Exoskeleton
… robots can be advanced by further development of pneumatic actuators. Pneumatic actuators are a good fit for exoskeleton robots because of their light weight, small size, and flexible materials. This is because a wearable robot should be human friendly, therefore, it should be light weight, slim, …

Deformations of the pneumatic tyre
A mathematical model is developed for the general pneumatic tyre. The model will permit the investigations of tyre deformations produced by arbitrary external loading, and will enable estimates to be made of the distributions of applied and reactive forces. The principle of Finite Elements is used …

Pneumatic Tire Performance on Ice
The evolution of vehicle safety systems, from the earliest brakes to today's accident avoidance systems, has led vehicles to have very high passenger safety. Driving on ice, though, still happens to be one of the driving conditions of low safety. A multitude of factors were identified by various …

Numerical Simulation on Dilute Phase Pneumatic Transport
Pneumatic conveying is a technique that is widely used in many industrial mechanical and chemical applications. In the case of cement manufacturing pneumatic conveying is a large scale operation moving several kilograms of material per second which consumes electrical energy (operation of fans) and …

Modeling and System Identification of Pneumatic Robot
Pneumatic actuators can prove to be really useful in robotics as they have natural backdrivability, good strength to weight ratio and lot of other interesting properties. However, they are quite difficult to control owing to their non linearity and high latency due to air’s compressability. One of …

Pneumatic variable stiffness soft robot end effectors
… dexterous gripper. The gripper uses contractor pneumatic muscles to control the motion of soft fingers. The soft nature of the gripper means it can deform if it collides with obstacles, and because grasping forces are spread over a larger area the chance of damaging the object being held is …

Soft pneumatic devices for blood circulation improvement
… the design, development and testing of some soft pneumatic flexible devices meant to apply an intermittent massage and to restore blood circulation in lower limbs in order to improve cardiac output and wellness in general. The choice of the actuators, as well as the pneumatic circuits and air …

A comprehensive analytical model for pneumatic tires
This study presents a comprehensive analytical tire model for both vehicle dynamic simulation and tire design. The model is composed of two parts--modeling of the contact mechanism and determination of the tire forces/moments. A static circular beam model is introduced for the contact mechanism, in …

Flow Around Cambered and Yawed Pneumatic Tyres
… conducted to study the flow around a deformed pneumatic tyre. An experimental rig is presented which enables an isolated tyre with Formula One inspired wheel geometry to be towed through a water towing tank at variable axle height, camber and yaw, with a highly accurate ground condition. This …

Pneumatic conveying in the dense and dilute phase
Pneumatic conveying is one of the backbones of chemical engineering as it has been used extensively in almost every industry. Yet many parameters involved in a usual conveying operation are not well understood. One important parameter is the solid concentration and solid flow behaviour after going …
