The Finite Element Of Analysis On The Frame Of A Recreational Vehicle

In recent years, domestic tourism in unceasing prosperity, with China’s traffic mode diversification, more user friendly, especially a big increase in the number of private cars, tourists travel to swim team mainly in the way, on the basis of the family gradually appeared driving tour, friends combination to swim, and network "I quite agree" the combination of self-help to travel more personalized way, and will present the trend of the development of the constantly. On the other hand, for the last30years, as our country’s birth and death rates are lower, China has entered into an aging society, a lot of retired old man has enough time, money and energy, and eager to go out for a walk to visit native land. Comprehensive these two reasons, to satisfy people travel and living two requirements of rv was more and more attention.Because rv travel involves collective travel, especially in the house for travel, therefore touring car design must be will safety in the first place. Taking a domestic saloon brand as the research object, the body frame is analyzed. The body frame is an important carrier of the car assembly parts, its just the merits of the strength of the service life of the vehicle and safety have a critical impact. At the same time, the car driving components are under dynamic loading are, therefore, it is necessary to body modal analysis.This article through the use of ANSYS software for a domestic rv skeleton of the finite element model of uniform linear was calculated respectively driven and round up condition, brake and turn on the four different working conditions of deformation and stress distribution of the skeleton, to make sure the car body frame of the stiffness and strength whether meet the design requirements. On the basis of the car body modal analysis, extraction of the car body form and vibration frequency vibration, finally, using the calculation results, the analysis of the natural vibration characteristics of the skeleton saloon car safety, comfort the effects for future research work provide the data support, and can better improve control stability of car, driving safety and ride comfort.
