Deformation Body for Vehicle Roll Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing deformation bodies for force and torque measurement in vehicle roll stabilization systems face challenges in balancing production ability, cost, material properties, weldability, and availability, particularly when using materials with high carbon, nickel, chromium, and cobalt contents that conflict with desirable welding properties.
Innovation Solution
A method involving the preparation of a support material and a central element, where the central element is securely attached to the support material using techniques like injection-molding, solid-body welding, or sintering, allowing for the production of a deformation body that can measure force and torque while ensuring secure attachment and effective operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If materials with high carbon, nickel, chromium, and cobalt contents are used for the deformation body, then measurement precision and durability are improved, but weldability and production ability deteriorate
Solution Approach 1:
The deformation body is divided into two separate components: a support material made from weldable standard steel and a central element made from magnetostrictive material with high carbon, nickel, chromium, and cobalt contents. This segmentation allows each component to be optimized for its specific function - the support material for ease of welding and production, and the central element for measurement precision - while avoiding the need to weld the high-alloy material directly.
Solution Approach 2:
The support material acts as an intermediary carrier that holds the central element in place. This intermediary structure enables the central element to be securely positioned without requiring direct welding of the high-alloy magnetostrictive material, thereby resolving the contradiction between measurement precision and manufacturability.
2Reliability
If the central element is securely attached to the support material, then reliability and operational stability are improved, but device complexity and production steps increase
Solution Approach 1:
The support material and central element are combined into a single integrated deformation body through secure attachment methods such as injection-molding, solid-body welding, or sintering. This merging ensures reliable operation during force and torque measurement while maintaining a unified structure that functions as a single component in the roll stabilization system.
