Simulation Analysis of Hinge Spring Based on Matlab and Adams_Hinge Knowledge_Aosite

Abstract: In the current automotive industry, there are issues with the long development cycle and inadequate motion analysis accuracy of automobile opening and closing parts. To address these problems, a kinematic equation for the hinge of a certain car model's glove box is established using Matlab, and the motion curve of the spring in the hinge mechanism is solved. Additionally, a virtual prototype model is created using the Adams dynamics software to simulate and analyze the dynamic characteristics of the operating force and displacement of the glove box. The analysis methods have good consistency, improving solution efficiency and providing a theoretical basis for optimal hinge mechanism design.

With advancements in the automobile industry and computer technology, customer demands for product customization have increased. Automobile design trends now include not only basic appearance and functionality, but also various research areas. The six-link hinge mechanism is widely used in the opening and closing parts of automobiles due to its attractive appearance, convenient sealing, and ability to control physical characteristics. However, traditional kinematics and dynamics analysis methods are unable to quickly provide accurate results that meet engineering design requirements.

Hinge Mechanism for Glove Box

The glove box in car cabs typically adopts a hinge-type opening mechanism, consisting of two springs and multiple connecting rods. The hinge linkage mechanism design requirements include: ensuring the initial position of the box cover and panel meet design requirements, providing a convenient opening angle for occupants to access items without interfering with other structures, and ensuring easy opening and closing operation with reliable locking in the maximum opening angle position.

Matlab Numerical Calculation

To analyze the motion of the hinge mechanism, the mechanism is first simplified into two four-bar linkages. Through simulation and calculations in Matlab, the motion curves of the two hinge springs are obtained. The displacement and force changes of the springs are calculated, providing insight into the motion law of the hinge mechanism.

Adams Simulation Analysis

A hinge six-link spring simulation model is established in Adams. Constraints and driving forces are added to obtain the displacement, velocity, and acceleration curves of the springs. The stroke and force curves of the springs during stretching and compression are calculated. The simulation results are compared to the analytical method results from Matlab, showing good consistency between the two methods.

The kinematic equations of the hinge spring mechanism are established and both Matlab analytical method and Adams simulation method are used to analyze the motion of the hinge mechanism. The simulation results demonstrate good consistency with the analytical results, improving solution efficiency. This research provides a theoretical basis for designing optimal hinge mechanisms.
