A Method for Calculating Opening Force and Closing Force of Automobile Tailgate Gas Spring

Ye, Wen

Gas spring layout is difficulty in the design process of tailgate system, Considering the influence of the environment on the inherent characteristics of the gas spring, it is important to accurately establish a calculation model that is similar to the actual situation when arranging the tailgate gas spring. This article describes such a method: use CATIA software to establish a gas spring support model, and then use a formula editor to establish mechanical equilibrium parameters, and then quickly and accurately obtain the gas spring installation point coordinates based on the parameters, finally, input the gas spring installation point coordinates into the Excel calculation program and define the influence of air temperature on the gas spring parameters, calculate the opening force and closing force at different temperatures and different opening angles, and judge the rationality of the gas spring arrangement based on the generated opening and closing force and temperature graph. This method reasonably and effectively solves the difficulty of tailgate gas spring arrangement: it can accurately calculate the opening and closing force of the gas spring which is similar to the actual situation, saves the arrangement time, and improves the accuracy and scientificity of the design
