The active load shall be applied on the cantrail of the superstructure through an absolutely rigid load application plane, which extends in both directions beyond the cantrail and any adjacent structure.

The Study of Bus Superstructure Strength Based on ECE R66

The manufacturer shall define unambiguously the superstructure of the bodywork see Figure A4. This shall be verified at any places of the passenger, driver’s and crew compartment where the residual space seems to be endangered, the exact positions being at the discretion of the technical service.

Specifications of Equivalent Approval Tests Instead of the roll-over test on a complete vehicle, at the discretion of the manufacturer, one of the following equivalent approval test methods can be chosen: Also, a rollover can cause up to five rotatio tions to occur on the road. The ee granted in respect of a vehicle type pursuant to this Regulation may be withdrawn if the requirements laid down in Paragraph 7. The simulation program shall be able to ecee the energy components for the energy balance at every incremental time step.

The PH’s shall utilise the actual dimensions of the pillars and structural elements on which they are located see Wce 1 of this Annex. A statement of whether or not the requirement of Paragraph 5. If the residual space is infringed during the roll-over simulation, the approval shall be refused.


Generally, any alteration from the fully finished condition is acceptable if the basic features and behaviour of the superstructure are not influenced by it. The asymmetry of the residual space, see Paragraph 5. The rollover scenario of an amphibious bus according to the ECE. Penalties for Non-conformity of Production 9.

Strength of the superstru tructure of large passenger vehicles. How important was vehicle safety in the new vehicle purchase process? In the case of a double deck vehicle, the rce of the passengers both on the lower and upper deck seats shall be taken into account.

FE model of the full vehicle was com comprised of ecs order shell elements, 73 spring elements and 44 mass elements ADMAS and 48 Rigid Elements. Modification and Extension of Approval of a Vehicle Type 7. Residual space is connected to the he high stiffness region on the axle which does notot affect a the structural strength in any manner.

Further work to optimize the bus structure in terms of weight, structural strength and crashworthiness is proposed. The direction of action of the active load shall not be changed during the calculation. Help Center Find new research papers cee The vehicle is an individual representative of a vehicle type.

Detailed mechanical description of the superstructure containing the location of PZ’s and PH’s and defining the rigid and elastic parts, 4.

The arrangement and number of these test pieces shall be agreed with the technical service. Which elements of the superstructure are assumed as rigid parts.

Drawings of the body sections to be tested; 1. All InterRegs documents are formatted as PDF files and contain the full text, tables, diagrams and illustrations of the original as issued by the national government authority. HeFei University of Technology,in Chinese. Brief summary of description of the superstructure r666 respect of Paragraph 3.


The Study of Bus Superstructure Strength Based on ECE R66

The centre of gravity position of the vehicle with total effective mass M may be determined: Whether, or not, the requirements – given in Paragraph 5. This support shall meet the following requirements: The current bus framework structure comprises galvanized square hollow sections SHS which are welded and bolted together.

The wheel supports at the widest axle shall be placed on the tilting platform so that the side of the tyre is at maximum mm from the axis of rotation; 1. The individual evaluation of the body g66 and their bays.

Log In Sign Up. The connecting structures between bays shall be clearly defined in the superstructure. Dimensions of the wheel support: If the equivalent approval test method chosen by the manufacturer cannot take account of some special feature or construction of the vehicle e.

Eve manufacturer shall clearly define the portion of the mass of the vehicle attributed to each of the bays of the superstructure. At least two positions, nominally at the front and rear of the passenger compartment s shall be used.
