In the 1990s, China entered a development period in which the construction of infrastructure such as highways, airports, and hydropower stations was accelerated. In order to improve the quality of roadbed foundation construction, domestic There is active demand for new compaction equipment.
In January 2019, a utility model patent application for a quadrilateral impact roller appeared in China. In the same year, South Africa's Blue Pai Company introduced two impact rollers (one triangular and one pentagonal) into the country for the first time. At present, my country leads the world in terms of production and sales of impact rollers. As of

year
, there are many impact rollers that have been applied in batches in domestic construction and have achieved good results, as well as foreign impact rollers constructed and sold in China.
:hmhd:dh:hmbd .:h Understanding the technical performance parameters of impact rollers is very important for users to select and use them correctly when purchasing. Here are some main technical performances and parameters of impact rollers.

Name of impact roller
:hmhd:dh:hmbd .:h The main names of domestic impact rollers are
Impact roller Real machine
High energy rolling compactor
Impact roller
Drag compactor
Impact compactor
, also appeared in relevant technical articles
Polygonal roller drag roller
Impact roller
etc. Most of the above names are derived from the translation of special terms for impact rollers that appeared in foreign countries at the end of the last century. The correct name should be translated into
impact rollers
. The reason is that it is not only in line with international standards, but also consistent with domestic standards such as vibratory rollers
(bR
) and oscillating rollers (R
). . As for
self-propelled (
),
towed
(
) or other forms of impact rollers developed in the future, a qualification can be added before its name. word. At present, the models of
impact rollers
are often represented by
,
which are Chinese Pinyin
roller
impact h
trailed h The first initial consonant of words such as
.
Indicates the calculated state energy, the unit is
(kilojoules).
Impact rollers
Most impact rollers have a trigonal impact wheel. For non-trigonal impact wheels, the number of polygons is placed in front of the basic model to identify them, such as
Kilojoule pentagon The
Impact Roller
of the impact wheel is expressed as
The
Impact Roller
of the kilojoule quadrilateral impact wheel is expressed as
. Regarding the identification of impact rollers with single and double impact wheels, it is recommended to only add an identification letter at the end of the model number of the single impact wheel. This is because most of the current impact rollers have double impact rollers. Impact wheel.

Impact energy of impact roller
:hmhd:dh:hmbd .:h The mass range of the impact wheel of the existing impact roller is ~
/>, and the static energy range is between ~
.
:hmhd:dh:hmbd .:h The static energy (
) calculation formula is (see figure
)
:hmhd:dh:hmbd .:h =
(R
)
:hmhd:dh:hmbd .:h Where:
Impact wheel mass (

:hmhd:dh:hmbd .:h
The radius of the circumscribed circle of the impact wheel (
)
:hmhd:dh:hmbd .:h
The radius of the inscribed circle of the impact wheel (
)
:hmhd:dh :hmbd .:h uses static energy to represent its parameters that are easy to measure and determine, so that users can have the same standard when choosing most products from various companies.
md:. :hmhd:dh: hmbd. :h The impact energy of the impact roller in the working state consists of three parts. The static energy is discussed in (
) formula. The total impact energy should also include translational energy. and rotational inertia energy, which will not be described in detail here.
