1.1 Hood Mounting Methods & LocationsCalculation Assumptions: Entire mass of vehicle is considered in the 2G bump force Assuming worst case condition, where the entire load is applied in shear Max. shear strength of LOCTITE® EA E-120HP adhesive = 20 N/mm^2 (is assumed to be equivalent to that of the adhesive being cured on Epoxy material for 12 hours @ 65 °C)
Table 1: Proposed Mounting Locations & Method for the Hood Panel Bonding to Adjacent Panels | Method | Validation/Rationale |
|---|
HeadlightsSide panels | Epoxy Adhesive | Bonding area calculations (Excel attached, below) | Windshield | Quarter-turn fasteners | Windshield must be removeable, quarter-turn fasteners will be used for windshield mounting to other panels | Bottom Panels | Epoxy Adhesive | Modify hood panel to have inward curve along the bottom edge to allow the panel to join with the bottom panel. |
