1、 Freight transportation

Different types of goods have different transportation requirements. Bulk materials such as steel, coal, and ore usually have lower transportation requirements, while electronic products, IT products, household appliances, etcHigh value sensitive goods place greater emphasis on transportation safety and timelinessOften, it is hoped that such goods can be delivered as safely and quickly as possible, so that they can enter the market as soon as possible to obtain greater value for the goods.

However, in transportation processes such as road transportation, railway transportation, and air transportationExtremely prone to vibration and impactIf vibration and impact cannot be absorbed, it will cause damage to the transported goods, therebyCausing serious economic losses.

ForHigh value and fragile productsEnsuring the safety of goods during transportation is of utmost importance, and such products are prone to being damaged during transportationVehicle loading and unloading, transportation bumps, and handling processesDue to damage, the transportation requirements are very high.How can we ensure the safety of goods during transportation?

2、 Characteristics of impact and vibration

Vibration is a periodic (mechanical) vibration of matter and objects, typicallyMedium to high frequencyandLow amplitudeVibration is described by its frequency. In addition, it is also stipulated that the device can withstandmaximum accelerationThey usually refer toMultiple of gravitational accelerationAt low frequencies, vibration is not defined by acceleration, but depends onObject amplitude within the vibration frequency rangeProlonged mechanical vibration may lead to material fatigue.

If an object experiences significant changes in velocity (acceleration) in the short term, this is calledmechanical shockFor example, during transportation, if a vehicle brakes suddenly or if goods fall, and an object hits the ground and suddenly decelerates, this situation can occur.

The impact is calculated as a multiple of the gravitational acceleration g=9.81m/s2. The huge impact can reach hundreds of grams in just a few milliseconds.

The impact has the following characteristics:

Acceleration axes x, y, and z in three perpendicular measurement directions;

Acceleration values ax, ay, and az in the direction of the acceleration axis;

x. Peak acceleration values of y and z axes or space vectors;

Main axis xyz (maximum) - the axis with the highest peak acceleration a (point on Figure 4);

The Random Alignment Space Vector of Acceleration in Impact EventsAcceleration value aR:

Examples of external impacts that affect the load during transportation:

Due to the fact that each load object responds to impact in a specific way, generally speaking, during actual stress (such as transportation), it should beAcceleration sensor experimentIdentify the objectmechanical stressandActual impact.

3、 Actual case

Trimos has been active in the field of industrial metrology since 1972, manufacturing a variety of products in the field of dimensional measurement technology. For example, in mechanical engineering, Trimos precision measuring instruments are used to measure various parts. The company's product export rate is as high as 95%. Based on regular evaluations of customer service data and complaints, the company has found that in most cases, product complaints are not due to material or production defects, but rather damage caused during transportation.

This not only caused customer frustration, but also resulted in high costs, time, and image loss for the company. Therefore, the company strives to design transportation routes to avoid equipment damage.

Data logger for objective data collection

in order toIdentify the cause of the damage and optimize the processTrimos chooses to useData logger testing shipmentIn order to more accurately assess transportation demand in the future. utilizeHK-MSR165 Micro Data Recorder(Thumb size, volume 39 * 23 * 72mm, weight only 69g, can be installed in narrow spaces), sensitive 200g sensor can recordAcceleration caused by movement on three axes: Front and back (x), left and right (y), up and down (z).

The data logger can alsoMeasure gravityTherefore, it is also possibleDetermine the actual locationBy determining the position and acceleration, analyzing the data can identify the load borne by the transported goodsloadHK-MSR165 is also equipped withtemperature sensor, in order toDetecting temperature curve.

When and where are the goods being transported impacted, how often does it occur, and what is the strength?

HK-MSR165Record every small change with accurate time information. Based on a detailed study, we can identify what exactly happened during transportation and what adjustments need to be made in terms of packaging, transportation routes, and transportation tools in the future.

The purpose of the first part of the test is toTest packaging performanceThis includes deploying a packaged high-sensitivity altimeter under different conditions (height, impact point location, etc.) to simulate the situations that occur during transportation. The test results revealed the weaknesses of the packaging, which is beneficialimprove packaging.

After successful completion of internal testing, proceed to real situation testing. Connect the HK-MSR165 data logger directly to the Trimos device. Sent together with the goods to some key delivery locations, in order toAssess the impacts and temperature differences experienced during transportationThe data logger stayed on the goods for about 10 days from leaving the factory to the destination. The test results are shown in the following figure as an example. The maximum load occurs on the y-axis, and temperature fluctuations are very obvious.

The analysis of measurement data shows that,stronglyThe impact occurred duringDuring the loading, unloading, and final transportation processTrimos has therefore improved packaging and optimized airline selection to protect equipment from the most critical direction (y) impact.

Therefore, data loggers use objective measurements to provide clear facts, which can be achieved through this approachSupport quality assurance in the transportation process of high-value goods.

4、 HK-MSR data logger provides escort for cargo transportation

Complex logistics has become a crucial part of every industrial and consumer value chain.Transportation and delivery routes——Whether simple or very complex - it can be seen everywhere in the globalized market. Therefore, relevant factors cannot be ignored under any circumstancesResponsibility and Quality Assurance Issues.
