For the calculation, the complete superstructure shall be mathematically modelled as a load-bearing and deformable structure, taking account of the following: Trade name or mark of the vehicle type: Verification of the validity of the distribution of masses given in R666 4, Paragraph 4. From the plotted load-deformation curve the actual energy absorbed by the body section E shall be r666 as the area below the curve see Figure A7.

On this basis, the energy absorbing capability of body section during the rollover process was studied and evaluated. It shall have an axis of rotation parallel to the longitudinal axis of the multi-axle section of the vehicle, and passing through the points of contact of the tyres of that section. The report on the simulation shall contain the following information: In this paper, a finite element model of a high-top cabin for heavy truck was built with commercial code Hypermesh, and a manikin according to ECE-R29 was added to the driver seat.

FRPRP and glass are included in the model which is an important nt component for structural integrity.

The Study of Bus Superstructure Strength Based on ECE R66

In most parts of the world, especia cially in Europe, safety requirements are continuo nuously visited to improve passenger safety in buses or coa oaches. A body section ecce at least two bays connected by representative connecting elements side, roof, and underfloor, structures.

The applied loads in the ee shall meet the following requirements: Rollover, Buss Structure, S Residual Space, Finite Element Method hod Abstract Bus rollover is one of the most serious type pes of accident as compared ec other modes of bus accidents nts.

Detailed drawings of the residual space according to Paragraph 5. That test was carried out according to this Annex; 4. That the tests were carried out according to this Annex 6. Wheel supports shall be applied at the wheels being close to the axis of rotation against sliding of the vehicle sideways when tilting it.

In the case of an artificial body section, the connecting structures shall be equivalent in terms of strength, stiffness and behaviour to that of the vehicle superstructure; 6.

During a bus or coach rollover, th the occupant will have a larger distance from the th center of rotation as compared to that of a car occupan ant. A drawing showing the mathematical model of the superstructure, 5. This support shall meet the following requirements: Taking a full-monocoque body as the research object, the finite element analysis theory was applied to build the finite element model of the bus and the numerical simulation environment of the structural strength of the superstructure.

As a second step, the complete vehicle rolls over simulation was wa performed.

The survival space of the cab was proved to be sufficient for the safety of the driver. Dimensions of the wheel support: This design method of rollover crash safety had important significance and value to research and development of manufacturer. The sum of the masses attributed to each bay shall be related to the mass M of the complete vehicle: Instead of the roll-over test on a com complete vehicle, at the discretion of the manufactu cturer, one of the following equivalent approval test methods canca be chosen: Drawings of the body sections to be tested; 1.

For design of truck cabin, the survival space must be guaranteed for the safety for driver and front seat passenger in event of crash, which is the legal requirement described in ECE-R29 regulation.

ECE approvals granted under this Regulation, in its original form, earlier than 60 months after the date of entry into force and all extensions of such approvals, shall remain valid indefinitely, subject to Paragraph Rce Thailand, according to the bus accident statistics referred to Department of Land Transport DLTthe highest risk represents the frontal crash accidents. The arrangement and number of these test pieces shall be agreed with the technical service.

By measuring the vehicle in total effective mass condition, or 1. Quasi-static loading tests of body sections in accordance with the specifications rce Annex 7.

The tilting platform shall be constructed to prevent the vehicle moving along its longitudinal axis. Each rigid section of an articulated vehicle may be tested r6 or in combination as described in Annex 5, Paragraph 2.
