Perforated Bar Armor for Vehicle Protection
Solution Overview
Problem
Existing bar armors for vehicle protection against cumulative projectile missiles are either too heavy due to the use of massive plates, compromising vehicle mobility, or they weaken the armor by incorporating perforations that reduce strength.
Innovation Solution
A lightweight bar armor design featuring a perforated bar panel with inclined flat bars and toothed edges, mounted on a frame with perforated attachments, providing a balance between low weight and high resistance through strategic perforation and hardening of the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If massive bars are used in bar armor, then protection effectiveness against cumulative projectile missiles is improved, but weight increases significantly
Solution Approach 1:
The bar armor utilizes a perforated plate structure with distributed holes, creating a porous configuration that reduces material usage and weight while maintaining protective function. The perforations allow the structure to intercept and disrupt cumulative projectiles without requiring solid massive bars, achieving weight reduction while preserving protection effectiveness.
Solution Approach 2:
The invention combines a perforated plate with a backing structure to form a composite armor system. The perforated plate serves as the first stage to intercept and disrupt incoming cumulative projectiles, while the backing structure provides additional protection and support, creating a multi-layer composite solution that optimizes both weight and protection effectiveness.
2Weight of moving object
If perforations are incorporated in bar armor to reduce weight, then weight decreases, but strength and resistance are weakened
Solution Approach 1:
The perforated plate features locally optimized properties with strategically positioned perforations that maintain structural integrity in critical areas while reducing weight in non-critical regions. The plate thickness and perforation distribution are varied locally to ensure sufficient strength for projectile interception while achieving overall weight reduction.
Solution Approach 2:
The armor structure is segmented into a perforated plate component and a backing structure component. The perforated plate is segmented with distributed holes to reduce weight, while the backing structure provides continuous support. This segmentation allows each component to be optimized independently for its specific function.
