FEM, Abaqus, Isight, optimization, DOE, elevator, guide rail. VTT-R-04402-15. Summary. The objectives of this Simpro subproject work was to create an optimization model by applying an industrial real case. The KONE Oy used elevator guide rail system was used as an example to the demonstration purposes.
Calculations -6© 4M s/n : F4295601565 . which causes bending stresses.2.Elevator Figure Z. it is allowed to consider an equal distribution of the forces between the guide rails.3 The bending stresses in different axes must be combined by taking into consideration the guide rail's cross section. loading" on the assumption
6 May 2007 Elevator Rail Bracket Improvement. Paul Hummeldorf. 13. DESIGN CALCULATIONS. The rail bracket was analyzed with a distance of 20 inches from mounting surface to the back of the guide rail for the car, and 16 ? inches from the mounting surface to the center of the counterweight rail for counterweight.
the sling grasp the guide rails, bringing the li to a smooth but rapid stop. At the foot of the 1st weU are buffers (usually . The result is that the guide forces are large when the lift is fully loaded, but of course lifts are only . approximation (Figure 16b), and then I can calculate the bending moment at each point load (Unit 11).
components, the calculations of guide rails depend mainly upon USA or European codes. Utsunomiya et. al. [4] invented a guide device for an elevator in which a pair of corresponding actuators were controlled in accordance with information from acceleration sensors, and the force with which guide members were pressed.
Elevator guide rails are components of elevator systems that define the path along which the elevators ride. An elevator should not be expected to operate regularly and safely on guide rails that do not possess the minimum quality standards and that are not installed properly. Data receivers which transmit to the control
22 May 2012 In this study, elevator guide rail calculation performed by taking as a reference a sample elevator project. Forces on the rails applied by the cabin skates were calculated in accordance with accounting principles in TS EN81-1 standard. Accounts from the guide rail forces, stress and deflection values were
In order to meet the requirements of high-speed elevators, a mathematic model of straightening process for elevator guide rails was built on the basis of elastoplastic mechanics. The relationship between deflection and bending moment and the relationship between curvature and the
a) Persons lifts: P = 100 + (50 x Passengers Number) (Kp) b) Other lift kinds: i). Q ? 500 Kp: P = 100 x (3 + Car surface area) (Kp) ii) Q > 500 Kp: P = 100 x (3 + (1.5 x Car surface area)) (Kp) b) Guide Rails. 1. General. 1.1 In order to meet the requirements of 10.1.1, the calculations of the guide rails, as shown below, are.
