A research on how to achieve self-closing through the reasonable layout of gas spring after passing the balance point during the closing of the engine cover. In order to achieve the goals of gas spring man-machine requirements, closing force and self-closing, etc., the optimal layout requirements for gas springs are proposed. From the energy point of view, the equations for the optimization and verification of gas spring layout are listed. Combined with an example of the optimization of the gas spring layout of an automobile aluminum engine cover, the specific location of the gas spring layout optimization is given, and the calibration calculation of each index is performed. The results show that the gas spring layout optimization method proposed is feasible and effective.
