Diksia.com - SEMARANG, Laksana Bodywork has successfully conducted a frontal crash test on a large bus using a simulation process using the parameters of Regulation No. of the United Nations Economic Commission for Europe. 29 or UN ECE R29 at their workshop in Ungaran, Central Java, today, Thursday 6 July 2023.
This crash test was attended by several bus operators who are customers of Karoseri Laksana, as well as officials from the Indonesian Ministry of Transport and the National Transport Safety Commission (NTSC).
A Karoseri Laksana crash test uses a model of a large Karoseri Laksana bus body, which is then hit from the front by a 1.5-ton pendulum to simulate a two-vehicle front-end collision and a goat fight. The driver puts a doll on the driver’s seat.
The test was conducted by impacting a thick steel pendulum weighing 1.5 tons on the front frame of the vehicle with an impact energy of 55 kJ and an impact speed of 8.56 m/s (31 km/h).
In order to pass this test, the driver’s safety area must be protected, which is then demonstrated by the presentation of a dummy that does not touch the structure.
A satisfactory result was obtained from the results of this collision. The frame structure of the bus body can save the driver from the risk of injury. The position of the driver’s legs is not pinched by the front of the body, as is often the case in head-on collisions on freeways or toll booths.
In addition, the frame structure of the front body of the bus is also able to protect the position of the core network from the danger of being stuck on the front body of the bus, because after this test, the front door of the bus can still be stuck open, too if no deformation occurs.
For the Laksana body, this front-end crash test will complement the various test results on the production bus body previously conducted with reference to United Nations Economic Commission for Europe (UNECE) safety regulations.
Standards for motor vehicles, especially buses and trucks, with regard to frontal impact protection.
