| Abstract: | Analyzing A pillar excessive distortion- the installation point of the front door hinge when a mini-car did a collision test on both its right side and its slanting side, the article proposes the optimization plan for this car invention in order to improve the impact strength of the fore-hatch structure in a vehicle under the collision in the right side and slanting collision, and also summarizes some design requirements for the fore-hatch structure in a vehicle. Based on the results of the test, this optimization plan can meet the needs of the national standard CMVDR294 that the front door can open after the crash. |
