Bulldozer Engine Mounting Reduces Duct Vibration Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bulldozers face increased load on ducts due to vibration, which shortens the life of connecting parts, as the distance between the engine's mounting part and the duct increases, leading to higher vibration transmission.
Innovation Solution
The bulldozer design incorporates a rear mounting part positioned higher than the front mounting part, reducing the vertical distance between the duct and the rear mounting part, thereby minimizing the load on the duct from vibration through the use of elastic materials and strategic positioning of the engine and air cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the air cleaner is mounted on the engine cover to achieve stable support, then the stability of the air cleaner is improved, but the load on the duct from vibration increases as the distance between the mounting part and the duct increases
Solution Approach 1:
The patent positions the rear mounting part higher than the front mounting part, creating a vertical height difference. This dimensional change in the mounting configuration shortens the vertical distance between the duct and the rear mounting part, thereby reducing vibration load on the duct while maintaining air cleaner stability.
Solution Approach 2:
The patent changes the vertical position parameter of the rear mounting part relative to the front mounting part. By adjusting this height parameter, the distance between the duct and mounting part is optimized to reduce vibration transmission while maintaining stable support.
2Stability of the object's composition
If the distance between the mounting part and the duct is increased, then the stability of engine support is improved, but the load on the duct from vibration increases
Solution Approach 1:
The patent introduces a vertical height difference between front and rear mounting parts. This dimensional change allows the rear mounting part to be positioned higher, shortening the vertical distance to the duct and reducing vibration load while maintaining engine support stability.
Solution Approach 2:
The mounting system uses asymmetric positioning where the rear mounting part is at a different height than the front mounting part. This asymmetric configuration optimizes the distance between the duct and rear mounting part to minimize vibration transmission.
