Truck Vibratory Source Weight Redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seismic data acquisition systems face limitations in distributing weight efficiently on vibratory sources mounted on vehicles, leading to suboptimal energy transmission to the ground, as the weight distribution is constrained by vehicle design, requiring oversized front wheels when additional weight is applied to the back wheels.
Innovation Solution
A system with a vehicle-mounted vibratory source and a balancing device that includes a lifting system and telescopic legs to redistribute weight from the wheels to the vibratory source, allowing for more efficient energy transmission by adjusting load distribution and lifting wheels off the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If additional weight is applied on the front wheels to increase weight on the vibratory source, then energy transmission to ground is improved, but front wheels and associated parts must be oversized
Solution Approach 1:
A hydraulic cylinder is introduced as an intermediary device between the truck bed and the vibratory source. This hydraulic system acts as a mediator to redistribute the weight, applying force to the front wheels through a mechanical linkage while simultaneously pressing down on the vibratory source, thereby achieving the desired weight distribution without requiring oversized front wheels
Solution Approach 2:
The system transitions from a static weight distribution to a dynamic one where the hydraulic cylinder can adjust the weight distribution in real-time. The hydraulic system allows the weight on the vibratory source and front wheels to be dynamically controlled, enabling optimization of energy transmission without permanent structural modifications to the vehicle
2Ease of manufacture
If vibratory source is mounted at the back of the truck, then ease of mounting is improved, but weight distribution on front wheels becomes excessive
Solution Approach 1:
The hydraulic cylinder serves as a mechanical intermediary that connects the rear-mounted vibratory source to the front wheel assembly. Through this intermediary system, the weight of the rear-mounted source is transmitted forward to the front wheels, allowing the source to remain easily mounted at the back while still achieving proper weight distribution on the front wheels for effective seismic energy transmission
