IVRESS/Elevator

IVRESS/Elevator is a time-accurate finite element / multibody dynamics tool for predicting the dynamic response of cable (including belt and steel rope) suspended elevators. IVRESS/Elevator allows elevator engineers to quickly build, analyze, and visualize elevators systems in an intuitive object-oriented graphical design environment. IVRESS/Elevator can be used to model elevator systems for hoisting people and cargo used in residential buildings, commercial buildings, hotels, airports, warehouses, factories, etc.

IVRESS/Elevator Features

Time-accurate explicit time integration finite element / multibody dynamics solver.
Accurate modeling of cable-sheave frictional contact using an asperity based Coulomb friction model.
Template/spreadsheet (Excel) user-friendly interface.
Supports flat belt, V-belt, and steel cable elevators.
Belts can be modeled using thin beam, thick beam, shell, and/or brick finite elements. Steel cables can be modeled using thin beam or thick beam elements.
Supports crowned sheaves for keeping flat belts centered.
Prediction of dynamic response quantities including:
- Sheave and idler pulley forces.
- Pulley angular velocities and torque.
- Span tensions.
- Span transverse vibrations.
- Belt-pulley slip.
- Belt-pulley normal and tangential force distribution.
Typical simulation scenarios.
- Elevator belt start and stop from any level.
- Steady-state operation at any speed or a range of speeds for studying the system natural frequencies.
- Introduction/removal of a disturbance such as dropping a heavy object inside the elevator.
- Tracking of belts on crowned sheaves.
