摘要

Sumitomo Wiring Systems, Ltd. designs and develops rubber grommets used for the protection and sealing of automotive wiring harnesses. These grommets are required to have good sealing properties, reduce the insertion force, and increase the pull-out force. To evaluate the insertion and pull-out forces, we use computer-aided engineering (CAE), in which the calculation results conform to the experimental results by reflecting the fractional force and material properties. We can also evaluate the change of the forces according to the surface roughness of grommets by CAE. For the sealing properties, we investigate water intrusion paths and the relations between water quantity, pressure, and leaks. This Paper reports on the results.
