When we think about devices that can help get surveys correctly, there is a device that does similar work. The device is a bump integrator. 

Let us know more about this critical device here: 

What Is A Bump Integrator?

A bump integrator is a tool used in the rear of vehicles, it analyzes unevenness in roads, which one can quantify using digital counters embedded in an LCD screen. 

An Integrator is a low-cost device fitted onto the back of a trailer that helps measure the irregularities on roads while driving. 

The trailer connects to a rubber tire via chassis. It contains an integrating device that tracks surface irregularities, so it measures via digital counters arranged on an LCD screen on the panel. 

• This device has been specially designed for manufacturers at the end of production lines. Quality control testers can count how many defects are there within each panel produced by measuring its unevenness index value (UI value). 

• The device is connected to the front suspension and consists of a rubber disc or bump plate attached to the bottom of a spring. When the vehicle drives over an uneven surface, it compresses the bumps, and the nodes cause a separation between the plate and spring. 

• The photodetectors measure the separation that translates it into measurements for roughness. Bump integrators are tools used in roughness surveys. They are part of a road profiler, electronic measuring equipment that measures unpaved roads.

Working Principle of Bump Integrator:

Now let us know about the bump integrator working principle. 

• The working principle of bump integrator is about measuring the vertical deflection of a pneumatic tire due to road irregularities and integrating the readings over a specified time interval, and displaying the results on an LCD screen in digital format. 
• The bump integrator, Using an air pressure sensor, the device measures the road bumps on highways. The pneumatic tire is somewhat different from an average car or bike tire. 
• The measurement the device calculates by subtracting two or three past bumps, thereby reducing the current bump duration and event frequency. 
• At the heart of a bump integrator, there is an integral equation. In road maintenance, one can use it to collect data on bumps to help smooth the surface of transport infrastructure. 
• It involves calculating the average distance between potholes over a set period. So this is the bump integrator working and how it measures deflection.

Uses of Bump Integrator:

Now that we know about the bump integrator working, let us know about the use of the bump integrator: 

• The Bump Integrator is an inexpensive option for measuring roughness and calculating IRI. When measuring road conditions, it must be placed on the ground at a known position, especially in remote areas where expensive systems cannot reach. Roughness (i.e., cross-country profile).
• It is a rugged, portable, and versatile vehicle-mounted bump integrator. Bump Integrator can measure the roughness of unpaved, wet, or rough roads. It is helpful for feasibility studies, research projects, and collecting roughness data for developing maintenance and forward works programs.
•  The Bump Integrator is a lightweight device that provides accurate data on road surface conditions. It can be easily attached to an onboard computer and wheels of a vehicle or placed in the driver’s seat. It enables real-time roughness surveys and the recording of roughness data.

Types of Bump Integrators: 

There are several types of Bump integrators; let us know about some of these here:

1. Vehicle-Mounted Bump Integrator:

The vehicle-mounted bump integrator is a device that determines the presence of an obstacle by analyzing data from the front bumper sensor. 

The VBI contains two sensors, called the contact sensor, that detects when the bumper comes in contact with an object. The other is called the ultrasonic sensor, which helps see things out of reach from the contact sensor. 

This system initiates the bumpers to emit low-frequency acoustic signals when encountering obstacles such as a curb or similar objects. The emitted vibrations alert drivers and pedestrians who are blind or visually impaired about their presence. 

The device, mounted on the frame of a vehicle, uses several accelerometers to detect vibrations as they pass through the car.

2. Fifth Wheel Bump Integrator:

The fifth wheel bump integrator is a device that can be used for measuring road roughness. It works on a response-type road roughness measuring system.

It works by altering the angle at which the trailer rides during transport and allows for proper clearance between the fifth wheel and trailer. It helps absorb the shock from bumps and rough roads, which prevents unwanted movement of the cargo. 

It supports the rear axle of a heavy vehicle and adds stability for heavy loads, and enables adjustment for the varying road surface. 

A fifth wheel bumper integrates with the trailer’s bumpers to create an integrated unit.

3. Microprocessor-Based Bump Integrator:

A microprocessor-based bump integrator is a device that continuously calculates the speed of a vehicle using a sensor. 

It is a practical device to calculate the car’s rate using accelerometer data collected from its microcontroller system. 

They have high accuracy, repeatability, low noise, and long-term stability, making them suitable for use in shock absorbers, automotive suspensions, and industrial equipment applications.

What is Bump Integrator Test?

The bump integrator test helps measure the bumps on the road. The system is composed of a carriage equipped with a bump integrator and two bump sensors. 

One sensor corresponds to the right wheel path, and the other saddle fits the left wheel path. Both circuits connect to the same engine circuit (ground). 

It measures how rough the road’s surface is, like a speed bump. It has an integrated computer to process and measure the bumps on surfaces like asphalt, concrete, etc.

How to Bump Integrator Test is Done?

The test procedure detects bumps in the road surface and calculates the IRI based on the vehicle’s suspension movement. 

The International Roughness Index (IRI) measures the surface profile. The average of maximum undulations and R-max is divided by the average smoothness of length or “Ls”. 

Smoothness is a measure of the level of comfort experienced by the travelling public while riding over a pavement surface. You can visit this guideline for more information.

As a piece of measuring equipment, the test measures the cumulative measure of vertical undulation of the pavement surface recorded per unit horizontal size of the road. 

It comprises a sensor that attaches to the axle and transmits data wirelessly to a central computer. The computer analyzes the data, which is displayed along with other road information on an LCD screen inside the car.

Methodology Chart for Bump Integrator Test:

1. Bump Integrator Test Specification:

• A Bump integrator test specification usually has a maximum operating speed of 30 ±½ km/hr. Running with an IRI (Integrated Road Infrastructure) head should relatively easily maintain a steady rate of 32km/hr.
• For bump integrators that are only useful in areas with no IRIS (Integrated Road Infrastructure Solutions) available such as rural areas where bumps need to be maintained. Setting the optimum speed and maintaining uniformity over all bumps at every section becomes difficult. 
• Different systems have been created that include innovative object detection limits and IRIS transponders to help organize traffic flow while balancing time, money, and labor on building routes from one destination to the next.

2. Bump Integrator Formula:

The Bump integrator machine helps identify the deflection with the help of a formula. Let us know about the Formula to obtain the pump integrator is:

Unevenness index= bumps in centimetre= length of section in kilometre

Bump Integrator Price:

A bump integrated is quite expensive as it has many applications in the industry. But if you put an average scale on the device’s price range, the bump integrator cost is around INR 2.5 lakhs to INR 5 lakhs. 

The bump integrator machine price depends upon the type of bump integrated one chooses and the product’s features.

Limitations of Bump Integrator Equipment:

As we know, Bump Integrator is a device that helps measure the road’s smoothness. It works on a shock absorber principle, i.e., it measures the bumpiness of the road surface by measuring the vibration while traveling over rough patches. But it has its fair share of limitations of bump integrator equipment:

• But in reality, it is pretty challenging to maintain a constant speed in using bump integrator equipment. Factors like brakes, wrong or broken springs, and even the engine’s running condition can affect its accuracy in measuring the smoothness of roads.
• A bump integrator is an expensive and time-consuming instrument for measuring the road surface, and therefore it is not feasible to use it on a routine basis.
