Application Background

Vehicle-mounted and shipboard display systems do not generate vibration themselves. However, during vehicle operation or ship navigation, external shocks and vibrations generated by engines, road conditions, waves, and structural movement can be transmitted to the display equipment.

Continuous vibration may cause fatigue damage to mounting brackets, connectors, and internal components, affecting the service life and reliability of the display system.

CaseStudy

Working Condition

A side-mounted vehicle TV/display system with a weight of 50 kg, a length of 1.9 m, and a height of 1.1 m was installed on a vehicle operating under long-term rough road conditions.

Due to continuous vibration and impact loads during operation, the fixing points of the display frequently failed, and an effective vibration isolation solution was urgently required.

Recommended Solution

Based on the customer's application requirements, Anlijing Vibration Reduction Technology Co., Ltd. recommended a wire rope isolator solution.

According to the display weight, dimensions, mounting method, operating environment, and road vibration conditions, a safety factor of 2.0 was applied during calculation.

After vibration isolation analysis and load matching, the recommended model was:

ALJ-81441 Wire Rope Isolator

Wire rope isolators are widely used in applications requiring vibration isolation, shock protection, and energy absorption, including:

· Vehicle-mounted equipment

· Shipboard and marine systems

· Military equipment

· Chemical and industrial equipment

· Aviation electronic systems

· Control systems

· Communication equipment

· Medical devices

· Mobile electronic instruments

Advantages of Anlijing Wire Rope Isolators

1. High-quality Corrosion-resistant Materials

Anlijing wire rope isolators are manufactured with:

· 304 stainless steel wire rope 

· 304 stainless steel mounting plates
(Except for standard 810 series models, which use aluminum alloy plates.) 

These materials provide excellent corrosion resistance and durability, making them suitable for harsh environments such as vehicles and marine applications.

2. Excellent Damping Performance and Shock Absorption Capability

Each strand of the wire rope is composed of 7 × 19 steel wires twisted together.

During vibration, relative movement and friction occur between individual wires, generating natural damping characteristics.

This structure enables the isolator to:

· Effectively reduce vibration transmission

· Absorb impact energy rapidly

· Protect sensitive equipment from shock and vibration damage

· Improve equipment reliability and service life

3. Strict Material Quality Control

Anlijing owns a full-spectrum spark direct-reading spectrometer to analyze material composition.

Each production batch undergoes material inspection to ensure the consistency and reliability of raw materials.

Side-mounted Installation Instructions

For side-mounted display applications, proper installation is critical to ensure optimal vibration isolation performance.

During installation:

1. Support the equipment securely before installation.

2. Install all isolators completely while the equipment is supported.

3. Only after all isolators are correctly installed should the equipment be lowered to allow the isolators to bear the load simultaneously.

Avoid applying the full load to individual isolators during installation, as uneven loading may cause premature deformation or reduce vibration isolation performance.
