TAILIEUCHUNG - Investigation of material effects on the passenger car’s frame structures in case of collision by Ansys LS-DYNA

This paper evaluated the effect of auto framing materials to passenger in collisions by Ansys LS-DYNA simulation software and analysis data by Hyperview software. Process simulation helps authors problem research, survey the feasibility of replacing traditional steel materials in the automotive manufacturing industry in Vietnam by carbon fiber composite materials. | TAÏP CHÍ PHAÙT TRIEÅN KH&CN, TAÄP 18, SOÁ K7- 2015 Investigation of material effects on the passenger car’s frame structures in case of collision by Ansys LS-DYNA Dr. Nguyen Khac Huan Engineering infantry institute (Manuscript Received on July 13th, 2015; Manuscript Revised October 16th, 2015) ABSTRACT This paper evaluated the effect of auto framing materials to passenger in collisions by Ansys LS-DYNA simulation software and analysis data by Hyperview software. Process simulation helps authors problem research, survey the feasibility of replacing traditional steel materials in the automotive manufacturing industry in Vietnam by carbon fiber composite materials. In addition, the simulation also allows the author to easily change the contact angle, the velocity of impact on a flexible, easy to achieve high economic efficiency during the actual test.

INTRODUCTION Reduced self-weight of cars and increased passive safety are two important factors when designing automobile frames, shell. During the design process, typically some parts anticollision on cars will be made from synthetic resin to absorb energy. Also partial skeleton structure is also designed to be able to absorb the highest energy is intended to increase the reliability and safety of people and vehicles. The examination of the anti-collision or safety for people and vehicles are evaluated by analyzing the collision process. Impact assessment process is usually done under the following methods: - Experiment; - Simulation the impact of the software. The first selection method with the accuracy and reliability but high cost and implementation process is extremely complex, so not suitable for the current conditions in Vietnam. The application of simulation software collision between two cars to solve the problems of reliability frame, shell and passive safety has brought high accuracy while reducing costs and time of
