Abstract: The paste reliability of sealing strips is very important for the continuous quality of vehicle noise, vibration, harshness (NVH). Compared with straight-line paste and outer-corner paste, the inner-corner paste of the sealing strip is more likely to be invalid. To improve the inner-corner paste reliability of the sealing strip, a compressive pasting process is proposed. The extra pressure generated by the compressive pasting process was investigated and a calculation model of the pressure on the inner fillet produced by the sealing strip was created, allowing the pressure to be calculated by the compression ratio. The extra pressure on the inner circle structure caused using the compression of the sealing strip was simulated. A pressure experiment conducted on the compressive sealing strip was completed and the relationship between the compression and additional pressure from the sealing strip was obtained and verified.
